Patent Application
20150044317
The present application relates to the use of lactic acid-producing bacteria in cosmetic compositions.
Probiotic organisms are non-pathogenic, non-toxigenic, and retain viability during storage. Since probiotics do not generally permanently colonize the host, they need to be administered regularly for any health promoting properties to persist.
The invention features a topical composition for the reduction of visible signs of aging comprising an extracellular product of Bacillus coagulans and a dermatologically acceptable carrier. For example, the composition comprises a mixture of extracellular products of the bacteria, e.g., in the form of a conditioned cell culture media. Preferably, the Bacillus coagulans comprises GBI-30 (ATCC Designation Number PTA-6086). The extracellular product comprises a liquid culture supernatant, is in the form of a dried powder, or is in the form of a reconstituted liquid from the dried powder. Suitable forms of the composition include an emulsion, a lotion, a cream, a serum, an oil, an ointment, a suspension, a gel, a powder, an aerosol powder, a scrub, a mask, an aerosol spray, a semi-solid formulation, a shampoo, and a conditioner.
In one aspect, the active agents are combined with a carrier or excipient that is physiologically compatible with the dermal or epithelial tissue of a human or animal to which it is administered. Suitable dermatologically acceptable carriers include hydrocarbon oils and waxes, silicone oils, vegetable, animal or marine fats or oils, glyceride derivatives, fatty acids or fatty acid esters or alcohols or alcohol ethers, lecithin, lanolin and derivatives, polyhydric alcohols or esters, wax esters, sterols and phospholipids. In some aspects, the extracellular product of Bacillus coagulans (e.g., supernatant) is dried, e.g., spray-dried, lyophilized, and/or fluid bed dried. For example, the extracellular product (e.g., supernatant) is dried (e.g., spray-dried, lyophilized, and/or fluid bed dried) onto a carrier (e.g., microcrystalline cellulose). In some aspects, the extracellular product (e.g., supernatant) is mixed with a carrier (e.g., microcrystalline cellulose) before drying the mixture by, e.g., spray-drying, lyophilizing, and/or fluid bed drying. For example, the extracellular product is mixed with a carrier to increase its bulk.
In one aspect, the extracellular product of Bacillus coagulans (e.g., supernatant) is combined with an extracellular product (e.g., supernatant) from another lactic acid producing bacterium. Exemplary lactic acid producing bacteria include Lactobacillus (e.g., Lactobacillus acidophilus, Lactobacillus plantarum, Lactobacillus delbrueckii, Lactobacillus johnsonii, or Lactobacillus gasseri).
In one example, the conditioned media or supernatant of Bacillus coagulans culture is harvested from Bacillus coagulans cells cultured for 1 day, 2 days, 3 days, 4 days, 5 days, 7 days, 10 days, or more. For example, the Bacillus coagulans cells are cultured until 10%, 20%, 40%, 60%, 70%, 80%, 90%, or more of the cells in the culture are dead. The supernatant is harvested by removing the cells and cell debri from the culture, e.g., by spinning down the culture (e.g., by centrifugation) and/or by filter-sterilizing the culture (e.g., through a 0.2 um or 0.13 um filter). The acellular conditioned culture media or supernatant is optionally further processed, e.g., by fractionation, concentration, or drying, or is added to dermatological product as is.
In one example, the supernatant comprises at least about 1% by volume (e.g., v/v) of the composition, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or at least 99% by volume of the composition. In another example, the supernatant (e.g., dried supernatant) comprises at least about 1% by weight (e.g., w/w) of the composition, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or at least 99% by weight of the composition.
In some cases, the compositions of the invention comprise an aging-reducing amount, i.e., an anti-aging amount, of the extracellular product of Bacillus coagulans bacterium. In another example, the extracellular product of Bacillus coagulans is present in an inflammation-reducing amount. For example, the extracellular product of Bacillus coagulans comprises between 1 μL and 100 L, e.g., between 10 μL and 10 L; between 100 μL and 1 L; between 1 mL and 100 mL; or about 10 mL. Alternatively, an anti-aging amount of the compositions of the invention comprises an amount that improves hydration/moisturization of treated skin, as measured by, e.g., Nova DPM 9003 (Gloucester, Mass.) by between 1% and 95%, as compared to a pre-treatment baseline level; improves skin elasticity/flexibility, as measured by, e.g., Cutometer SEM 575 (Courage+Khazaka Electronic GmbH, Köln, Germany), by between 1% and 95%, as compared to a pre-treatment baseline; reduces fine lines and wrinkles, as measured by e.g., Visioscan® VC 98, (Courage+Khazaka Electronic GmbH, Köln, Germany), by between 1% and 95%, as compared to a pre-treatment baseline level; reduces under eye, as determined by, e.g., photographic evaluation utilizing the R.W. Johnson Pharmaceutical Research Institute descriptive scale (Griffiths et al., 1992 Arch Dermatol, 128(3): 347-351, incorporated herein by reference), by between 1% and 95%, as compared to a pre-treatment baseline level; reduces under eye dark circles, as determined by, e.g., photographic evaluation utilizing the R.W. Johnson Pharmaceutical Research Institute descriptive scale (Griffiths et al., 1992 Arch Dermatol, 128(3): 347-351, incorporated herein by reference), by between 1% and 95%, as compared to a pre-treatment baseline level; reduces skin inflammation, as determined by, e.g., photographic evaluation, by between 1% and 95%, as compared to a pre-treatment baseline level; decreases skin pore size, as determined by, e.g., photographic evaluation, by between 1% and 95%, as compared to a pre-treatment baseline level; decreases skin roughness, as measured by e.g., Visioscan® VC 98, (Courage+Khazaka Electronic GmbH, Köln, Germany), by between 1% and 95%, as compared to a pre-treatment baseline level; or decreases skin redness, as determined by, e.g., photographic evaluation, by between 1% and 95%, as compared to a pre-treatment baseline level.
In some cases, the composition contains at least 1%, 2%, 5%, 10%, 15%, 20%, 25%, 30%, 40%, 50%, or more (by weight or volume) of an extracellular product of Bacillus coagulans. For example, the extracellular product of Bacillus coagulans contains a liquid or dried (e.g., lyophilized) supernatant of Bacillus coagulans. In some instances, the composition contains at least 1%, 2%, 5%, 10%, 15%, 20% 25%, 30%, 40%, 50%, or more of Bacillus coagulans liquid supernatant by volume (v/v) or weight (w/w). In other instances, the composition contains at least 1%, 2%, 5%, 10%, 15%, 20% 25%, 30%, 40%, 50%, or more of Bacillus coagulans dried (e.g., lyophilized, fluid bed dried, and/or spray-dried) supernatant by weight (w/w) or volume (v/v).
The extracellular product of Bacillus coagulans bacterium comprises compounds, e.g., anti-inflammatory or anti-aging compounds, ranging from 3 kDa to 200 kDa, inclusive, e.g., compounds less than 3 kDa; compounds ranging from 3 kDa to 30 kDa; compounds ranging from 30 kDa to 200 kDa; and compounds ranging from 25 to 75 kDa.
Optionally, the composition further comprises from about 0.1% to about 10% by weight of a penetration enhancer selected from the group consisting of sulfoxides, alcohols, polyols, alkanes, fatty acids, esters, amines and amides, terpenes, surface-active agents, cyclodextrins, lactic acid, and mixtures thereof. For example, the composition further comprises about 18% by weight or by volume of lactic acid. In some cases, the extracellular product of Bacillus coagulans is lyophilized or is in the form of a reconstituted liquid from dried powder, i.e., the extracellular product is dried (e.g., freeze-dried, vacuum dried, air dried, or dried by application of heat) and subsequently reconstituted.
An exemplary formulation comprising Bacillus coagulans extracellular product includes the following ingredients: Bacillus coagulans extracellular product, water, isopropyl myristate, isocetyl stearate, glycerin, ricinus communis (castor) seed oil, hydrogenated vegetable oil, vegetable oil, hydrogenated castor oil, acetyl alcohol, polyacrylamide, c13-14 isoparaffin, laureth-7, ethylhexyl methoxycinnamate, squalene, laneth-16, ceteth-16, oleth-16, steareth-16, caprylyl glycol, phenoxyethanol, hexylene glycol, and fragrance.
Drying and reconstituting Bacillus coagulans extracellular product (metabolites/supernatant) in, e.g., saline, results in unexpected anti-inflammatory effects. For example, drying the Bacillus coagulans extracellular product (metabolites/supernatant) inactivates or removes undesirable compounds (e.g., volatile organic compounds <30 kDa) that would otherwise inhibit the anti-inflammatory effects of the Bacillus coagulans extracellular product prior to drying and rehydration. In some cases, the dried and reconstituted Bacillus coagulans extracellular product is spray-dried to remove the undesirable compounds. Exemplary components present in the Bacillus coagulans extracellular product include peptidoglycan from lysed cell walls and/or lipoteichoic acid (LTA).
Culture supernatants that are dried and subsequently rehydrated are useful in products where conditions are not optimal for transportation of large volumes of liquid. Specifically, culture supernatants that are dried and subsequently rehydrated are useful in any situation where an anti-inflammatory effect is desired. For example, dried and reconstituted Bacillus coagulans extracellular product contains 1-200 kDa compounds that reduce migration of inflammatory cells (e.g., leukocytes, phagocytes, monocytes, lymphocytes, and polymorphonuclear leukocytes (PMNs)) and induce the production of anti-inflammatory cytokines (e.g., interleukin-4 (IL-4), IL-6, and tumor necrosis factor alpha (TNFα)).
A method for the topical treatment or reduction of visible signs of aging in a subject is carried out by topically applying to affected skin the composition described above. In some cases, the skin to be treated is not characterized by a pathologic microbial infection such as an infection by a pathologic virus (e.g., Herpes simplex viruses I and II), yeast (e.g., Candida albicans and C. tropicalis), fungus (e.g., Trichophyton mentagrophytes, T. interdigitale, and T. rubrum, and T. yaoundei), or bacteria (e.g., Staphylococcus aureus, S. epidermidis, Streptococcus pyogenes, Pseudomonas aeruginosa, Escherichia coli (enterohemorragic species), Clostridium perfingens, C. Gardnerella vaginalis, Propionibacterium acnes, Aeromonas hydrophilia, Aspergillus species, Proteus species, and Klebsiella species), i.e., the skin does not comprise a dermal pathogen. The method leads to a surprising reduction in visible signs of aging after at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, or more days of treatment.
For example, hydration/moisturization of treated skin is improved (e.g., decrease in transepidermal water loss), as measured by, e.g., Nova DPM 9003 (Gloucester, Mass.) by at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline level. Skin elasticity/flexibility is improved, as measured by, e.g., Cutometer SEM 575 (Courage+Khazaka Electronic GmbH, Köln, Germany), by at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline. Fine lines and wrinkles are reduced, as measured by e.g., Visioscan® VC 98, (Courage+Khazaka Electronic GmbH, Köln, Germany), by at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline level. Under eye puffiness is reduced, as determined by, e.g., photographic evaluation utilizing the R.W. Johnson Pharmaceutical Research Institute descriptive scale (Griffiths et al., 1992 Arch Dermatol, 128(3): 347-351, incorporated herein by reference), by at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline level. Under eye dark circles are reduced, as determined by, e.g., photographic evaluation utilizing the R.W. Johnson Pharmaceutical Research Institute descriptive scale (Griffiths et al., 1992 Arch Dermatol, 128(3): 347-351, incorporated herein by reference), by at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline level. Skin inflammation is reduced, as determined by, e.g., photographic evaluation, by at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline level. Skin pore size is decreased, as determined by, e.g., photographic evaluation, by at least at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline level. Skin roughness is decreased, as measured by e.g., Visioscan® VC 98, (Courage+Khazaka Electronic GmbH, Köln, Germany), by at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline level. Finally, skin redness is decreased, as determined by, e.g., photographic evaluation, by at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline level.
For example, as described in the examples below, at 4 weeks, the cream plus supernatant increases skin hydration by 7.13% more than a placebo cream. In another example, the cream plus Bacillus coagulans supernatant increases skin moisturization by 19.05%. As described in the examples below, the cream plus supernatant increases skin elasticity by 3.11% more than a placebo cream. As described in the examples below, the cream plus supernatant decreases the number of coarse skin lines by 20.57% more than a placebo cream. In another example, the cream plus Bacillus coagulans supernatant decreases skin roughness by 19.44%. In another example, the cream plus supernatant increases skin smoothness by 4.33% more than a placebo cream. In yet another example, the cream plus supernatant decreases skin shadows by 7.09% more than a placebo cream. As described in the examples below, on visual evaluation, the cream plus supernatant results in a 17% increase in the number of subjects showing improvement of eye area fine lines and wrinkles more than a placebo cream. In another example, the cream plus Bacillus coagulans supernatant decreases skin wrinkle and fine lines by 71.50% compared to only a 12.79% reduction with placebo cream. Finally, as described in the examples below, the cream plus supernatant results in an 8.33% increase in the number of subjects showing improvement of under eye puffiness more than a placebo cream.
The subject is preferably a mammal in need of such treatment, e.g., a subject that has visible signs of aging or a predisposition thereto. For example, the subject is identified as suffering from visible signs of aging or a predisposition thereto by detecting a sign or symptom selected from the group consisting of fine lines or wrinkles around the eye area, under-eye puffiness, dark under-eye circles, rough skin, reduced skin hydration/moisturization, increased transepidermal water loss, increased desquamation, decreased epidermal barrier integrity, decreased ceramide synthesis, vertical wrinkles above the lip (also known as smoker's kiss), loss of underskin matrix, reduced rosacea, reduced eczema, and reduced skin elasticity/flexibility. The mammal can be, e.g., any mammal, e.g., a human, a primate, a mouse, a rat, a dog, a cat, a horse, as well as livestock or animals grown for food consumption, e.g., cattle, sheep, pigs, chickens, and goats. In a preferred embodiment, the mammal is a human. In some cases, the subject has smoked or currently smokes. In some cases, the subject is female, e.g., a female smoker or a female whom formerly smoked. For example, the subject has suffered from environmental damage, e.g., from sun (e.g., ultraviolet radiation), wind, and/or extreme (e.g., cold or hot) temperatures.
The invention provides a method to treat existing environmentally damaged skin in a subject comprising topically applying to affected skin a composition comprising an anti-aging amount of an extracellular product (e.g., a supernatant) of Bacillus coagulans and a dermatologically acceptable carrier.
The invention also provides a method for alleviating one or more symptoms of rosacea in a subject comprising topically applying to affected skin of the subject a topical composition of the invention. For example, the subject in need thereof has one or more symptoms of rosacea, including frequent flushing of the face, neck, chest, scalp or ears; persistent facial redness; small red solid bumps on the face, neck, chest, scalp or ears; pus-filled pimples on the face, neck, chest, scalp or ears; visible blood vessels on the face, neck, chest, scalp or ears; burning or stinging sensations on the face, neck, chest, scalp or ears; itching or feeling of tightness on the face, neck, chest, scalp or ears; dry and rough central facial skin; irritated eyes; red and swollen eyelids; facial swelling; skin thickening and enlargement on the face; and raised red patches of skin on the face, neck, chest, scalp or ears.
The invention further provides a method for preventing or alleviating sun exposure-associated inflammation (e.g., caused by sunburn) in a subject. The method includes topically applying to affected skin of the subject a topical composition disclosed herein. The topical composition is applied to the affected skin prior to, during, and/or after sun exposure. The topical composition reduces one or more symptom of inflammation caused by sunburn. For example, the topical composition reduces symptoms including hot, red, tender skin; pain when the skin is rubbed or touched; dehydration; blistering of the skin; swelling of the skin; peeling of the skin; a welt; and a rash.
In addition, the invention provides a method for alleviating inflammation in a subject by topically applying to affected skin of the subject a topical composition disclosed herein. The subject will undergo, is undergoing, or has undergone a laser procedure. The topical composition is applied to the affected skin prior to (e.g., 15 min, 30 min, 1 h, 2 h, 6 h, 12 h, 24 h, 2 days, 5 days, 7 days, or more prior to), during, and/or after (e.g., 15 min, 30 min, 1 h, 2 h, 6 h, 12 h, 24 h, 2 days, 5 days, 7 days, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 3 months, 5 months, 9 months, 12 months, or more after) the laser procedure. The topical composition reduces one or more symptom of inflammation caused by a laser procedure. For example, the symptoms include redness, swelling, itching, stinging, raw skin, blisters, oozing liquid from treated areas, dryness, and peeling.
In some cases, the compositions of the invention comprise an aging-reducing amount, i.e., an anti-aging amount, of the extracellular product of Bacillus coagulans bacterium. In another example, the extracellular product of Bacillus coagulans is present in an inflammation-reducing amount. For example, the extracellular product of Bacillus coagulans comprises between 1 μL and 100 L, e.g., between 10 μL and 10 L; between 100 μL and 1 L; between 1 mL and 100 mL; or about 10 mL. In some cases, the extracellular product of Bacillus coagulans is lyophilized. In other cases, the extracellular product of Bacillus coagulans is dried (e.g., freeze-dried, vacuum dried, or air dried) and reconstituted.
Exemplary bacterial species for the compositions and methods described herein include Bacillus coagulans, e.g., Bacillus coagulans hammer, preferably Bacillus coagulans hammer strain Accession No. ATCC 31284, or one or more strains derived from Bacillus coagulans hammer strain Accession No. ATCC 31284 (e.g., ATCC Numbers: GBI-20 (GB-20), ATCC Designation Number PTA-6085; GBI-30 (GB-30/Ganeden BC30™/BC30), ATCC Designation Number PTA-6086; and GBI-40 (GB-40), ATCC Designation Number PTA-6087; see, U.S. Pat. No. 6,849,256 to Farmer). Preferably, the Bacillus coagulans comprises GBI-30 (BC30), or any strain of the organism described in U.S. Ser. No. 11/706,642, hereby incorporated by reference. The Bacillus coagulans Hammer strains of the invention are non-pathogenic and generally regarded as safe for use in human nutrition (i.e., GRAS classification) by the U.S. Federal Drug Administration (FDA) and the U.S. Department of Agriculture (USDA), and by those skilled in the art.
Exemplary formulations of the compositions of the invention include an emulsion, a lotion, a cream, an oil, an ointment, a suspension, a gel, a powder, an aerosol powder, a scrub, a mask, an aerosol spray, a semi-solid formulation, a shampoo, a serum, and a conditioner. In some instances, the formulation of the composition includes a cream. The compositions of the invention are administered topically, e.g., to the skin. The compositions are administered at least once per day, e.g., at least twice per day, at least 3 times per day, at least 4 times per day, or at least 5 times per day. Preferably, the compositions are administered for at least 24 hours, at least 48 hours, at least 72 hours, or for at least 7 days, at least 14 days, at least 28 days, at least 30 days, at least 60 days, at least 90 days, or for at least 4 months, at least 6 months, at least 9 months, or for at least 1 year, at least 2 years, or at least 3 years.
Drying and reconstituting Bacillus coagulans extracellular product (metabolites/supernatant) in, e.g., saline, results in unexpected anti-inflammatory effects. Drying the Bacillus coagulans extracellular product (metabolites/supernatant) inactivates or removes undesirable compounds (e.g., volatile organic compounds <30 kDa) that would otherwise inhibit the anti-inflammatory effects of the Bacillus coagulans extracellular product prior to drying and rehydration. For example, the dried and reconstituted Bacillus coagulans extracellular product is spray-dried to remove the undesirable compounds. In some cases, components present in the Bacillus coagulans extracellular product include peptidoglycan from lysed cell walls and/or lipoteichoic acid (LTA).
Culture supernatants that are dried and subsequently rehydrated are useful in products where conditions are not optimal for transportation of large volumes of liquid. Specifically, culture supernatants that are dried and subsequently rehydrated are useful in any situation where an anti-inflammatory effect is desired. For example, dried and reconstituted Bacillus coagulans extracellular product contains 30-200 kDa compounds that reduce migration of inflammatory cells (e.g., leukocytes, phagocytes, monocytes, lymphocytes, and polymorphonuclear leukocytes (PMNs)) and induce the production of anti-inflammatory cytokines (e.g., interleukin-4 (IL-4).
Dried and reconstituted Bacillus coagulans extracellular product is also useful in the various cosmetic, e.g., anti-aging, products described herein, which increase skin hydration/moisturization, increase skin elasticity, reduce the appearance of rough skin, fine lines, and wrinkles, reduce the appearance of under eye puffiness/under eye dark circles, and reduce skin inflammation. Dried and reconstituted Bacillus coagulans extracellular product is also useful in topical formulations designed to inhibit the growth of bacteria, fungus, yeast, and mycotic pathogens, thereby improving local skin flora.
For example, drying and reconstituting the Bacillus coagulans extracellular product results in at least 1% greater anti-inflammatory or anti-aging activity compared to Bacillus coagulans extracellular product alone, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 99% greater anti-inflammatory or anti-aging activity compared to Bacillus coagulans extracellular product alone.
Also provided is a composition comprising a dry powder comprising acellular culture supernatant of Bacillus coagulans in a eukaryotic tissue culture medium. By “acellular culture supernatant” is meant a culture supernatant that is substantially free of cell walls, cell wall fragments, and other cellular components. For example, the cells are separated from the culture supernatant by a centrifuge. In some cases, the medium is serum free medium. Suitable media include Roswell Park Memorial Institute (RPMI)-1640 medium, Dulbecco's modified eagle medium (DMEM), Eagle's minimal essential medium (EMEM), minimal essential medium (MEM), Iscove's modified Dulbecco's media (IMDM), Ham's medium, minimal essential medium alpha (AMEM), Glasgow minimal essential medium (GMEM), and Hank's balanced salt solution medium (HBSS).
Other suitable media are described in U.S. Pat. No. 6,383,810 (incorporated herein by reference), and include MCDB 131, MCDB 153, MDEM, M199, McCoy's 5A, Williams' Media E, Leibovitz's L-15 Medium, Grace's Insect Medium, IPL-41 Insect Medium, TC-100 Insect Medium, Schneider's Drosophila Medium, Wolf & Quimby's Amphibian Culture Medium, cell-specific serum-free media (SFM) such as those designed to support the culture of keratinocytes, endothelial cells, hepatocytes, melanocytes, etc., F10 Nutrient Mixture and F12 Nutrient Mixture. Other media, media supplements, and media subgroups suitable for preparation by the invention are available commercially (e.g., from Life Technologies, Inc.™; Rockville, Md., and Sigma-Aldrich®; St. Louis, Mo.). Formulations for these media, media supplements and media subgroups, as well as many other commonly used animal cell culture media, media supplements and media subgroups are well-known in the art and may be found, for example in the GIBCO/BRL Catalogue and Reference Guide (Life Technologies, Inc.™; Rockville, Md.) and in the Sigma-Aldrich® Cell Catalogue (Sigma; St. Louis, Mo.).
Also provided is a topical composition for the reduction of visible signs of aging comprising an isolated Bacillus coagulans bacterium and a dermatologically acceptable carrier. For example, the compositions of the invention comprise an aging-reducing amount, i.e., an anti-aging amount of an isolated Bacillus coagulans bacterium itself. In another example, the Bacillus coagulans is present in an inflammation-reducing amount. For example, an anti-aging amount of the Bacillus coagulans comprises between 0.1 mg and 10 grams, e.g., about 1 mg to about 10 grams, about 10 mg to about 5 grams; about 100 mg to about 2 gram; or about 200 mg to about 1 gram. Alternatively, an anti-aging amount of the Bacillus coagulans comprises an amount that improves hydration/moisturization of treated skin, as measured by, e.g., Nova DPM 9003 (Gloucester, Mass.) by between 1% and 95%, as compared to a pre-treatment baseline level; improves skin elasticity/flexibility, as measured by, e.g., Cutometer SEM 575 (Courage+Khazaka Electronic GmbH, Köln, Germany), by between 1% and 95%, as compared to a pre-treatment baseline; reduces fine lines and wrinkles, as measured by e.g., Visioscan® VC 98, (Courage+Khazaka Electronic GmbH, Köln, Germany), by between 1% and 95%, as compared to a pre-treatment baseline level; reduces under eye, as determined by, e.g., photographic evaluation utilizing the R.W.

Any of a variety of methods for placing the bacterial composition into a composition can be used. However, preferred methods include a “spray-dry” method in which the compositions are exposed in a low humidity chamber to an atomized mix containing a liquid composition, where the chamber is subsequently exposed to approximately 80-110° F. to dry the liquid, thereby impregnating the material of composition with the components.
A typical concentration is from approximately 1×107 to 1×1012 colony forming units (CFU); 1×108 to 1×1011 CFU; or 1×109 to 1×1011 CFU of viable bacterium or spores/g of composition. In one aspect, the amount of bacteria is about 104 to 1014 CFU of bacteria per gram of probiotic composition (i.e., vegetative cells and/or bacterial spores), preferably 105 to 1013 CFU/g of composition. Alternatively, the concentrations are 108 to 1013 CFU/g; 109 to 1012 CFU/g; or 1010 to 1011 CFU/g of composition. For example, the composition comprises about 1×106, 2×106, or 5×107 CFU Bacillus coagulans bacteria (per gram of composition) in the form of spray-dried powder. The actual amount in a composition will vary depending upon the amounts of composition to be dispersed into the composition and upon routes of dispersal. Following drying, the composition is ready for immediate use or for storage in a sterile package.
The Bacillus coagulans bacterium comprises compounds, e.g., anti-inflammatory or anti-aging compounds, between 3 kDa and 200 kDa, e.g., compounds less than 3 kDa; compounds between 3 kDa and 30 kDa; and compounds between 30 kDa and 200 kDa.
The isolated Bacillus coagulans bacterium is in the form of a spore or a vegetative cell. In some cases, the isolated Bacillus coagulans is in the form of a spore. Alternatively, the isolated Bacillus coagulans is in the form of a vegetative cell. In another aspect, the isolated Bacillus coagulans is in the form of a mixture of vegetative cells and spores. The Bacillus coagulans is predominantly in spore form, e.g., about 75%, about 80%, about 85%, about 90%, about 95%, about 96%, about 97%, about 98%, about 99%, or about 100% spores. For example, the Bacillus coagulans comprises 99.9% spores. Alternatively, the Bacillus coagulans is predominantly in vegetative form, e.g., about 75%, about 80%, about 85%, about 90%, about 95%, about 99%, or about 100% vegetative cells. In some cases, the Bacillus coagulans bacterium is lyophilized.
The composition is in the form of an emulsion, a lotion, a cream, an oil, an ointment, a suspension, a gel, a powder, an aerosol powder, a scrub, a mask, an aerosol spray, a semi-solid formulation, a shampoo, or a conditioner. In some cases, the composition is in the form of a dried powder.
The Bacillus coagulans bacteria (e.g., spores or vegetative cells) comprise at least about 1% by volume of the composition, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or at least 99% by volume of the composition. For example, Bacillus coagulans in the form of dried powder comprises at least 1% by volume of the composition. In another example, the Bacillus coagulans bacteria (e.g., spores or vegetative cells) comprise at least about 1% by weight of the composition, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or at least 99% by weight of the composition. For example, Bacillus coagulans in the form of dried powder comprises at least 1% by weight of the composition.
The Bacillus coagulans bacterium is viable or non-viable. For example, the non-viable Bacillus coagulans bacterium is inactivated, irradiated, heat killed or dead.
Optionally, the composition further comprises from about 0.1% to about 10% by weight of a penetration enhancer selected from the group consisting of sulfoxides, alcohols, polyols, alkanes, fatty acids, esters, amines and amides, terpenes, surface-active agents, cyclodextrins, and mixtures thereof.
As stated above, exemplary bacterial species for the compositions and methods described herein include Bacillus coagulans, e.g., Bacillus coagulans hammer, preferably Bacillus coagulans hammer strain Accession No. ATCC 31284, or one or more strains derived from Bacillus coagulans hammer strain Accession No. ATCC 31284 (e.g., ATCC Numbers: GBI-20 (GB-20), ATCC Designation Number PTA-6085; GBI-30 (GB-30/Ganeden BC30™/BC30), ATCC Designation Number PTA-6086; and GBI-40 (GB-40), ATCC Designation Number PTA-6087; see, U.S. Pat. No. 6,849,256 to Farmer). Preferably, the Bacillus coagulans comprises GBI-30 (BC30), or any strain of the organism described in U.S. Ser. No. 11/706,642, hereby incorporated by reference.
A method for the topical treatment or reduction of visible signs of aging in a subject is carried out by topically applying to affected skin a composition comprising an isolated Bacillus coagulans bacterium and a dermatologically acceptable carrier. As described in detail above, suitable Bacillus coagulans bacterium strains include GBI-30 strain (ATCC Designation Number PTA-6086), GBI-20 strain (ATCC Designation Number PTA-6085), and GBI-40 strain (ATCC Designation Number PTA-6087). In some cases, the skin to be treated is not characterized by a pathologic microbial infection such as an infection by a pathologic virus, yeast, fungus, or bacteria, i.e., the skin does not comprise a dermal pathogen. Alternatively, the composition inhibits the growth of pathogenic bacteria, fungus, or yeast. The method leads to a surprising reduction in visible signs of aging in a subject after at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, or more days of treatment. For example, the composition is administered to a subject in need thereof at least once per day, twice per day, three times per day, or more.
In some embodiments, the composition modulates expression of a gene or a protein that affects transepidermal water loss, desquamation, epidermal barrier integrity, ceramide synthesis, or a combination thereof.
In some aspects, the composition decreases transepidermal water loss. For example, the composition increases the expression of an aquaporin protein or a gene encoding an aquaporin protein. Exemplary aquaporin proteins include aquaporin 1 (AQP1), aquaporin 2 (AQP2), aquaporin 3 (AQP3), and aquaporin 4 (AQP4). The composition increases the level of expression of an aquaporin protein or a gene encoding an aquaporin protein by at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline level. The composition increases the level of expression of an aquaporin protein or a gene encoding an aquaporin protein by at least 2-fold, 5-fold, 10-fold, 20-fold, or more, as compared to a pre-treatment baseline level.
A decrease in transepidermal water loss can be determined by methods commonly known in the art, e.g., b using a Tewameter as described in Jennemann, et al. J. Biol. Chem. 2007, 282:3083-3094 and Herrmann, T. et al. J. Cell Biol. 2003, 161:1105-1115, the contents of both incorporated herein by reference. The composition decreases the level of transepidermal water loss by at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline level. The composition decreases the level of transepidermal water loss by at least 2-fold, 5-fold, 10-fold, 20-fold, or more, as compared to a pre-treatment baseline level.
In addition or alternatively, the composition decreases desquamation, e.g., by decreasing the expression of a kallikrein protein or a gene encoding a kallikrein protein. Exemplary kallikrein proteins include kallikrein 1 (KLK1), kallikrein 2 (KLK2), kallikrein 3 (KLK3), kallikrein 4 (KLK4), kallikrein 5 (KLK5), kallikrein 6 (KLK6), kallikrein 7 (KLK7), kallikrein 8 (KLK8), kallikrein 9 (KLK10), kallikrein 11 (KLK11), kallikrein 12 (KLK12), kallikrein 13 (KLK13), kallikrein 14 (KLK14), or kallikrein 15 (KLK15). In some embodiments, kallikrein protein comprises kallikrein 6 (KLK6). The composition decreases the level of expression of a kallikrein protein or a gene encoding a kallikrein protein by at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline level. The composition decreases the level of expression of a kallikrein protein or a gene encoding a kallikrein protein by at least 2-fold, 5-fold, 10-fold, 20-fold, or more, as compared to a pre-treatment baseline level.
A decrease in desquamation can be determined by methods commonly known in the art. For example, the extent of desquamation is quantified by measuring the amount of corneocytes that are released from the surface of the stratum corneum of skin tissue. Corneocytes are recovered from the surface of the tissue via sonication, and treated with SDS at a high temperature to convert them into cross-linked proteins. The proteins can then be quantified by any means commonly known in the art. For example, the proteins are quantified immobilizing them on a membrane (e.g., PVDF or nitrocellulose) and then treating the membrane with a dye that binds to proteins. With this assay, the dye intensity is proportional to the amount of protein released from the surface of the skin, which is in turn proportional to the extent of desquamation. The dye intensity can be quantified via densitometry and/or the extent of desquamation can be assessed by histology. The composition decreases the level of desquamation by at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline level. The composition decreases the level of desquamation by at least 2-fold, 5-fold, 10-fold, 20-fold, or more, as compared to a pre-treatment baseline level.
Also, the composition increases epidermal barrier integrity, e.g., by increasing the level of expression of a cadherin protein or a gene encoding a cadherin protein. Cadherin proteins include desmocollin, cadherin, protocadherin, and desmoglein. In some embodiments, the cadherin protein comprises a desmocollin protein, e.g., desmocollin 1 (DSC1). The composition increases the level of expression of a cadherin protein or a gene encoding a cadherin protein by at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline level.

An increase in epidermal barrier integrity can be determined by methods commonly known in the art, e.g., a skin permeability assay, as described in Jennemann, et al. J. Biol. Chem. 2007, 282:3083-3094; Herrmann, T. et al. J. Cell Biol. 2003, 161:1105-1115; and Matsuki, M. et al. Proc. Natl. Acad. Sci. U.S.A. (1998) 95:1044-1049, the contents of which are each incorporated by reference. The composition decreases skin permeability by at least 1%, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 11%, at least 12%, at least 13%, at least 14%, at least 15%, at least 16%, at least 17%, at least 18%, at least 19%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95%, as compared to a pre-treatment baseline level.

An increase in ceramide synthesis can be determined by commonly known methods in the art. For example, cells are provided in vitro with a radiolabeled precursor (e.g., 3H-sphinganine). Ceramide synthesis is initiated by the addition of the precursor and palmitoyl CoA. Then, the lipids are extracted from the cells and dihydroceramide is quantified by thin layer chromatography (TLC). Other examples of methods for determining ceramide synthesis levels are found in Modrak, et al. Methods in Molecular Medicine, Vol. 111, 2005, pp. 183-194; Reynolds, et al.

The subject is preferably a mammal in need of such treatment, e.g., a subject that has visible signs of aging or a predisposition thereto. For example, the subject is identified as suffering from visible signs of aging or a predisposition thereto by detecting a sign or symptom selected from the group consisting of fine lines or wrinkles around the eye area, under-eye puffiness, dark under-eye circles, rough skin, reduced skin hydration/moisturization, cracked skin, and reduced skin elasticity. The mammal can be, e.g., any mammal, e.g., a human, a primate, a mouse, a rat, a dog, a cat, a horse, as well as livestock or animals grown for food consumption, e.g., cattle, sheep, pigs, chickens, and goats. In a preferred embodiment, the mammal is a human.
For example, the compositions of the invention comprise an aging-reducing amount, i.e., an anti-aging amount of an isolated Bacillus coagulans bacterium itself. In another example, the Bacillus coagulans is present in an inflammation-reducing amount. For example, the Bacillus coagulans comprises between 0.1 mg and 10 grams, e.g., about 1 mg to about 10 grams, about 10 mg to about 5 grams; about 100 mg to about 1 gram; or about 200 mg to about 1 gram. In some cases, the Bacillus coagulans bacterium is lyophilized. In other cases, the Bacillus coagulans is dried (e.g., freeze-dried, vacuum dried, or air dried) and reconstituted.
The composition is in the form of an emulsion, a lotion, a cream, an oil, an ointment, a suspension, a gel, a powder, an aerosol powder, a scrub, a mask, an aerosol spray, a semi-solid formulation, a shampoo, a serum, or a conditioner. In some cases, the composition is in the form of a dried powder.
The compositions are administered topically, e.g., to the skin. The compositions are administered at least once per day, e.g., at least twice per day, at least 3 times per day, at least 4 times per day, or at least 5 times per day. Preferably, the compositions are administered for at least 24 hours, at least 48 hours, at least 72 hours, or for at least 7 days, at least 14 days, at least 28 days, at least 30 days, at least 60 days, at least 90 days, or for at least 4 months, at least 6 months, at least 9 months, or for at least 1 year, at least 2 years, or at least 3 years.
The Bacillus coagulans bacterium is viable or non-viable. For example, the non-viable Bacillus coagulans bacterium is inactivated, irradiated, heat killed or dead.
Also provided are methods for topically reducing visible signs of a skin disorder in a subject by topically applying to affected skin a composition comprising an isolated Bacillus coagulans bacterium or an extracellular product thereof and a dermatologically acceptable carrier. For example, the skin disorder is acne. In some cases, the Bacillus coagulans extracellular product is dried and reconstituted.
Purified and/or isolated Bacillus coagulans or Bacillus coagulans extracellular product is particularly useful in the methods and compositions described herein. By “purified” or “substantially purified” is meant a Bacillus coagulans bacterium or Bacillus coagulans extracellular product that is substantially free of contaminating microorganisms or other macromolecules, e.g., polysaccharides, nucleic acids, or proteins. A purified composition comprising Bacillus coagulans bacteria or Bacillus coagulans bacteria extracellular product contains at least 75%, 85%, 95%, or 100% of the desired composition and is substantially free of other sub-cellular components such as cytoplasmic organelles. A purified composition comprising Bacillus coagulans bacteria is at least 60% the desired strain relative to the total population of cells. Preferably, the composition comprising Bacillus coagulans bacteria is at least 75%, more preferably at least 90%, and most preferably at least 99%, the desired strain relative to the total population of cells. For example, a purified population of bacteria is one that is at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% the desired strain relative to the total population of cells.
By the terms “effective amount” and “therapeutically effective amount” of a formulation or formulation component is meant a sufficient amount of the formulation or component, alone or in a combination, to provide the desired effect. For example, by “an effective amount” is meant an amount of a compound, alone or in a combination, required to reduce visible signs of aging. Ultimately, the attending physician or veterinarian decides the appropriate amount and dosage regimen.
The terms “treating” and “treatment” as used herein refer to the administration of an agent or formulation to a clinically symptomatic individual afflicted with an adverse condition, disorder, or disease, so as to effect a reduction in severity and/or frequency of symptoms, eliminate the symptoms and/or their underlying cause, and/or facilitate improvement or remediation of damage. The terms “preventing” and “prevention” refer to the administration of an agent or composition to a clinically asymptomatic individual who is susceptible or predisposed to a particular adverse condition, disorder, or disease, and thus relates to the prevention of the occurrence of symptoms and/or their underlying cause.
The transitional term “comprising,” which is synonymous with “including,” “containing,” or “characterized by,” is inclusive or open-ended and does not exclude additional, unrecited elements or method steps. By contrast, the transitional phrase “consisting of” excludes any element, step, or ingredient not specified in the claim. The transitional phrase “consisting essentially of” limits the scope of a claim to the specified materials or steps “and those that do not materially affect the basic and novel characteristic(s)” of the claimed invention.
Other features and advantages of the invention will be apparent from the following description of the preferred embodiments thereof, and from the claims. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, suitable methods and materials are described below. All published foreign patents and patent applications cited herein are incorporated herein by reference. Genbank and NCBI submissions indicated by accession number cited herein are incorporated herein by reference.

In the case of conflict, the present specification, including definitions, will control. In addition, the materials, methods, and examples are illustrative only and not intended to be limiting.
The Bacillus coagulans bacterium described herein (e.g., ATCC Numbers: GBI-20 (GB-20), ATCC Designation Number PTA-6085; GBI-30 (GB-30/Ganeden BC30™/BC30/BC30), ATCC Designation Number PTA-6086; and GBI-40 (GB-40), ATCC Designation Number PTA-6087; see, U.S. Pat. No. 6,849,256 to Farmer), along with the extracellular products (i.e., metabolites/supernatants) thereof are useful in topical cosmetic formulations. The topical cosmetic formulations contain a supernatant obtained from the culture of B. coagulans, e.g., BC30. The supernatant is the metabolic byproduct produced during bacterial fermentation. It is naturally derived from Ganeden BC30, an organism that is generally regarded as safe (GRAS). The supernatant includes the following compounds: naturally derived L+ lactic acid, bacteriocin, hydrogen peroxide, enzymes, and other metabolites. The supernatant of Bacillus coagulans is referred to herein as Bonicel.
The cosmetic formulation described herein reduces inflammation, improves skin elasticity, improves skin hydration, reduces the appearances of fine lines and wrinkles, reduces under eye puffiness, reduces under eye dark circles, decreases skin pore size, reduces skin roughness, reduces skin redness, and/or improves skin flora, e.g., by reducing bacterial levels, reducing fungal levels, or reducing yeast levels. For example, the composition optionally inhibits the growth of pathogenic bacteria, fungus, or yeast. Delivery of the composition for skin care is accomplished using the supernatant or vegetative cells formulated into lotions, creams, gels, powders, scrubs, masks, shampoos, or conditioners.
The Effect of Bacillus coagulans Bacterium and Extracellular Product on Inflammation
The health benefits of the extra-cellular materials produced by Bacillus coagulans bacteria during their respective fermentation processes are described herein. The extra-cellular material called “supernatant” contains enzymes, lactic acid, hydrogen peroxide, bacteriocins, and other materials that are beneficial to a host.
The benefits of the supernatant from lactic acid bacteria on localized and systemic immune function are described in detail below. The compounds present in the supernatant from these bacteria have a profound effect on immune function as it pertains to accelerated healing and disease mitigation. These compounds include peptidoglycans, Lipotechoic acids and other organic molecules, which have a significant effect on inflammation and other host-cell interactions.
Inflammation is part of the complex biological response of skin and vascular tissues to harmful stimuli, such as pathogens, damaged cells, allergens and antigens. Inflammation is a protective attempt by the body to remove deleterious stimuli and to initiate the healing process through cytokine expression. Inflammation is a stereotyped response, and is considered a mechanism of innate immunity, as compared to adaptive immunity, which is specific for each pathogen or allergen.
Inflammation is important to disease mitigation. Without it, infections would never heal. As a result, progressive destruction of the tissue would compromise the survival of the organism or body. However, continued inflammation at the site of a wound after antibiotics or other anti-infective compounds are utilized can have deleterious effects on the healing process by restricting circulation to the infected site and prolonging the painful symptoms that accompany the infection. For this reason, steroid preparations are commonly utilized with many anti-infective strategies. This is also true with autoimmune and allergenic induced inflammation.
Inflammation can be classified as either acute or chronic. Acute inflammation is the initial response of the body to harmful stimuli, and is achieved by the increased movement of plasma and leukocytes from the blood into the injured tissues. A cascade of biochemical events (cytokine activity) propagates the inflammatory response, involving the local vascular system, the immune system, and various cells within the injured tissue. Prolonged inflammation, known as chronic inflammation, leads to a progressive shift in the type of cells present at the site of inflammation, and is characterized by simultaneous destruction and healing of the tissue from the inflammatory process.
Most of the unpleasant symptoms of an infection are the result of inflammation. By reducing the inflammation, the symptoms of the infection are reduced as well. In the case of athlete's foot, which is caused by the fungal species Thichophyton, very unpleasant symptoms accompany the infection. These symptoms may include itching, redness, burning and the formation of painful cracks in the skin that can bleed and lead to secondary infections. By reducing the inflammation associated with this fungal infection, circulation to the infected site is increased which allows nutrients and immune cells to migrate to the site to enhance recovery and accelerate the healing process. This mechanism is the same for other infections as well.
In addition, the compositions and methods reduce one or more symptoms of eczema. Eczema symptoms include itchy, red, and dry skin caused by inflammation. Eczema is also called atopic dermatitis. Diagnosis of eczema is commonly based on history and physical examination, e.g., the occurrence of one or more symptoms of eczema.
In addition, the compositions and methods also reduce one or more symptoms of rosacea. Rosacea is a chronic condition characterized by facial redness, flushing, and/or pimples. Rosacea affects both men and women, with a peak onset at 30 to 60 years of age. Individuals with fair skin who tend to flush or blush easily are at higher risk for developing rosacea. Left untreated, rosacea worsens over time. Typically, rosacea starts as redness in the central region of the face, though it can also manifest as redness in the neck, chest, ears, and scalp. Symptoms, such as frequent blushing or flushing, visible blood vessels, irritated eyes (e.g., watery or bloodshot eyes, red and swollen eyelids), burning or stinging sensations in the face, itching or a feeling of tightness in the face, rough and/or dry central facial region, isolated raised red patches on the skin that develop without changes in the surrounding skin, skin thickening and enlargement from excess tissue (e.g., on the nose (rhinophyma)), facial swelling, small red solid bumps or pus-filled pimples that lack blackheads, and/or persistent facial redness (that resembles a blush or sunburn) can also occur. These symptoms may develop beyond the face, e.g., on the neck, chest, scalp, or ears. Rosacea is diagnosed by the presence of one or more of these symptoms.
Redness of the skin is both a cause of rosacea as well as a symptom. For example, triggers that lead to flushing or blushing (e.g., heavy exercise, sunlight, sunburn, stress, hot weather, cold weather, indoor heat, wind, anxiety, humidity, hot baths, alcohol consumption, heated beverages, spicy foods, topical irritants, medications, certain cosmetics, acne and wrinkle treatments, isotretinoin, benzoyl peroxide, tretinoin, topical or nasal steroids, microdermabrasion, and chemical peels) can lead to development of rosacea.
There are four subtypes of rosacea. Subtype 1 (erythematotelangiectatic rosacea) is characterized by flushing and persistent redness, and may also include visible blood vessels. Subtype 2 (papulopustular rosacea) is characterized by persistent redness with transient bumps and pimples. Subtype 3 (phymatous rosacea) is characterized by skin thickening, often resulting in an enlargement of the nose from excess tissue. Subtype 4 (ocular rosacea) is characterized by ocular manifestations such as dry eye, tearing and burning, swollen eyelids, recurrent styes and potential vision loss from corneal damage. Patients can experience characteristics of more than one subtype at a time.
The compositions are useful in the reduction of inflammation associated with sunburn and/or alleviation of a symptom of sunburn. Sunburn is an inflammatory response caused by overexposure to ultraviolet (UV) radiation from the sun, which damages the skin and/or eyes. Symptoms of sunburn include hot, red, tender skin; pain when the skin is rubbed or touched; dehydration; blistering, swelling, and/or peeling of the skin; and welts and/or rashes. Symptoms of severe sunburn include fever, nausea, chills, dizziness, rapid pulse, rapid breathing, dehydration, and shock. Individuals with fair skin and/or with certain diseases (e.g., albinism, lupus, porphyria, rosacea, eczema, vitiligo, and xeroderma pigmentosum) are at higher risk for sunburn. Also, individuals taking certain medications that increase photosensitivity are at higher risk for sunburn. Exemplary medications that increase photosensitivity include but are not limited to antidepressants, antihistamine, antimicrobials, antiparasitics, antipsychotics, ACE inhibitors, diuretics, sulfonylureas, non-steroidal anti-inflammatory drugs (NSAIDs), contraceptives, sulfonamides, thiazide diuretics, and tetracyclines. Additional examples of medications that increase photosensitivity are found in Levine. “Medications that Increase Sensitivity to Light: A 1990 Listing.” U.S. Department of Health and Human Services, HHS Publication FDS 91-8280. (1990):1-20, incorporated herein by reference.
Additionally, the compositions are used in the reduction of inflammation and/or a symptom of inflammation caused by a laser procedure. An example of a laser procedure is laser skin resurfacing, which removes unwanted, damaged skin one layer at a time, to remove certain undesired conditions (e.g., fine lines or wrinkles around the eyes, forehead, or mouth; scars; non-responsive skin after facelift; aged skin; sun-damaged skin; liver spots; warts; birthmarks; enlarged oil glands on the nose; or yellowish or grayish skin tones). Laser skin resurfacing is used, e.g., on the face, hands, neck, and/or chest. Other examples of laser procedures include removal of diseased tissues, closing of small blood vessels, removal of tumors, treatment of bunions, removal of scars, removal of tattoos, removal of moles, removal of sunspots, removal of dilated blood vessels from the face; removal of hair; and removal of skin cells that could turn into cancer (actinic keratosis). Laser procedures can lead to inflammation, including symptoms such as redness, swelling, itching, stinging, raw skin, blisters, oozing liquid from treated areas, dryness, and peeling. Types of lasers used for the laser procedures disclosed herein include but are not limited to carbon dioxide, erbium, argon, neodymium-doped yttrium aluminum garnet (Nd:YAG), and Potassium titanyl phosphate (KTP).
Described in detail below is the liquid fermentation product or supernatant of Bacillus coagulans BC30. The Bacillus coagulans supernatant is manufactured under strict current good manufacturing practices (cGMP) guidelines using the most modern fermentation equipment and infrastructure. In clinical trials, the Bacillus coagulans supernatant modulates systemic and localized immune function, and assists the body in making proper immune decisions. This modulation includes down-regulation of inflammatory cytokine expression through a number of host-cell interactions between bacterial cell wall components.
For example, the immune modulating activity of the Bacillus coagulans supernatant includes: increasing systemic lymphocyte proliferation, increasing the maturation rate of dendritic cells, increasing Natural Killer Cell (NK) activation, favorably modulating TNF and other cytokine expression, reducing C-reactive protein (Systemic Inflammation Score), and increasing CD4 cell ratios in HIV+ patients.
As described in detail below, the Bacillus coagulans supernatant/fermentation product (e.g., supernatant of Ganeden Biotech BC30) is a safe and effective compound for reduction of inflammation associated with infections and allergic reactions. Decreased inflammation score directly translates to reductions in the associated symptoms of infections (e.g., burning, itching, pain, swelling, redness, heat, and accumulation of immune cells), allergic reactions, and topical auto-immune manifestations, reduced incidence of secondary infection, and faster/accelerated healing.
As described in detail below, the Bacillus coagulans extracellular product (i.e., supernatant/fermentation product) has favorable effects on skin that is damaged by the consequences of aging or general exposure by reducing pore size, redness, roughness, wrinkles and fine lines, increasing hydration, reducing puffiness, and increasing elasticity. For example, in the anti-aging studies described below, the Bacillus coagulans supernatant decreased fine lines and wrinkles by 50%, increased skin hydration by 16.20%, reduced under eye puffiness by 8.33%, and increased general skin elasticity by 10.97%. Bacillus coagulans supernatant also decreased skin pore size by 27%-58%, decreased skin roughness by 20%, and reduced skin redness by 62%.
The Bacillus coagulans supernatant/fermentation product is formulated into virtually any cosmetic product without losing its activity. Formulations include, inter alia, creams, lotions, gels, shampoos, and cream rinses.
The bacteria described herein are non-pathogenic, non-toxigenic, and retain viability during storage. Since probiotics do not generally permanently colonize the host, they need to be administered regularly for any health promoting properties to persist. A probiotic lactic acid-producing bacterium suitable for use in the methods and compositions of the invention produces acid and is non-pathogenic. Purified and/or isolated Bacillus coagulans or the extracellular product of Bacillus coagulans is particularly useful as a probiotic in the compositions described herein. By “purified” or “substantially purified” is meant a Bacillus coagulans bacterium or the extracellular product of a Bacillus coagulans bacterium that is substantially free of contaminating microorganisms or other macromolecules, e.g., polysaccharides, nucleic acids, or proteins.
Purified defines a degree of sterility that is safe for administration to a human subject, e.g., lacking infectious or toxic agents. Specifically, as used herein, an “isolated” or “purified” Bacillus coagulans or extracellular product is substantially free of other cellular material or culture medium. A purified composition comprising Bacillus coagulans bacteria or an extracellular product of a Bacillus coagulans bacterium contains at least 75%, 85%, 95%, or 100% of the desired composition and is substantially free of other sub-cellular components such as cytoplasmic organelles. A purified composition comprising Bacillus coagulans bacteria is at least 60% the desired strain relative to the total population of cells. Preferably, the composition comprising Bacillus coagulans bacteria is at least 75%, more preferably at least 90%, and most preferably at least 99%, the desired strain relative to the total population of cells. For example, a purified population of bacteria is one that is at least 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% the desired strain relative to the total population of cells. Purity is measured by any appropriate standard method.
The compositions include a lactic acid-producing bacterium, such as a spore-forming Bacillus species, e.g., B. coagulans. Preferably, the spore-forming Bacillus species of the invention is B. coagulans Hammer or a species derived therefrom. There are many suitable bacteria identified as described herein, although the invention is not limited to currently known bacterial species insofar as the purposes and objectives of the bacteria is described. The property of acid production is important to the effectiveness of the probiotic lactic acid-producing bacteria of this invention.
Exemplary methods and compositions are described herein using Bacillus coagulans extracellular product or Bacillus coagulans itself as a cosmetic agent. Purified Bacillus coagulans extracellular product is particularly useful in the compositions described herein. B. coagulans is non-pathogenic and is generally regarded as safe (i.e., GRAS classification) by the U.S. Federal Drug Administration (FDA) and the U.S. Department of Agriculture (USDA), and by those skilled in the art.
Bacillus coagulans
Bacillus coagulans is a non-pathogenic gram positive spore-forming bacteria that produces L (+) lactic acid (dextrorotatory) in fermentation conditions. It has been isolated from natural sources, such as heat-treated soil samples inoculated into nutrient medium (Bergey's Manual off Systemic Bacteriology, Vol. 2, Sneath, P. H. A., et al., eds., Williams & Wilkins, Baltimore, Md., 1986). Purified B. coagulans strains have served as a source of enzymes including endonucleases (e.g., U.S. Pat. No. 5,200,336), amylase (U.S. Pat. No. 4,980,180), lactase (U.S. Pat. No. 4,323,651), and cyclo-malto-dextrin glucano-transferase (U.S. Pat. No. 5,102,800). B. coagulans has been used to produce lactic acid (U.S. Pat. No. 5,079,164). A strain of B. coagulans (referred to as L. sporogenes; Sakaguti & Nakayama (ATCC 31284)) has been combined with other lactic acid producing bacteria and B. natto to produce a fermented food product from steamed soybeans (U.S. Pat. No. 4,110,477).
Bacterial species include Bacillus coagulans, e.g., Bacillus coagulans hammer, preferably Bacillus coagulans hammer strain Accession No. ATCC 31284, or one or more strains derived from Bacillus coagulans hammer strain Accession No. ATCC 31284 (e.g., ATCC Numbers: GBI-20, ATCC Designation Number PTA-6085; GBI-30 (BC30), ATCC Designation Number PTA-6086; and GBI-40, ATCC Designation Number PTA-6087; see U.S. Pat. No. 6,849,256 to Farmer).
Bacillus coagulans was previously mis-characterized as a Lactobacillus and labeled as Lactobacillus sporogenes (Nakamura et al. 1988. Int. J. Syst. Bacteriol. 38: 63-73). However, initial classification was incorrect because Bacillus coagulans produces spores and excretes L (+)-lactic acid through metabolism. Both of these characteristics provide key features to the utility of Bacillus coagulans. These developmental and metabolic aspects required that the bacterium be classified as a lactic acid Bacillus.
In one aspect, a Bacillus coagulans strain is included in the composition in the form of vegetative cells. In another aspect, the Bacillus coagulans strain is included in the composition in the form of spores. Preferably, the Bacillus coagulans extracellular product or supernatant is utilized as a cosmetic agent in the compositions described herein. The invention also provides for including the Bacillus coagulans strain in the composition in the form of a powder, a dried cell mass, a stabilized paste, or a stabilized gel.
Because Bacillus spores are heat and pressure-resistant and can be stored as a dry powder, they are particularly useful for formulation into and manufacture of cosmetic compositions. Specifically, the probiotic organisms described herein, e.g., Bacillus coagulans strain GBI-30 or BC30, ATCC Designation Number PTA-6086, can withstand the manufacturing process of cosmetic products. A Bacillus species is well suited for the present invention, particularly species having the ability to form spores which are relatively resistant to heat and other conditions, making them ideal for storage (shelf-life) in product formulations. Due to the shelf-stable properties of the Bacillus coagulans strains described herein, e.g., Bacillus coagulans strain GBI-30 or BC30, ATCC Designation Number PTA-6086, the product formulations of the invention are not confined to a refrigerator and may be stored at room temperature. The Bacillus coagulans of the invention survives storage (shelf-life) from about 12 days to about 2 years; from about 1 month to about 18 months; from about 3 months to about 1 year; or from about 6 months to about 9 months.
The invention is directed to the surprising discovery that the extracellular products of lactic acid-producing bacteria, particularly Bacillus species, reduce the visible signs of aging. Specifically, the probiotic organisms described herein, e.g., Bacillus coagulans strain GBI-30 or BC30, ATCC Designation Number PTA-6086, improve skin hydration/moisturization, improve skin elasticity, reduce the appearance of fine lines and wrinkles around the eye area, decrease the appearance of under-eye puffiness and dark circles, reduce the appearance of skin inflammation, reduce skin pore size, reduce skin roughness, and decrease skin redness.
The Bacillus coagulans extracellular product or Bacillus coagulans itself is topically administered. Any of a variety of methods for providing a bacterial composition can be used. In one aspect, a “spray-dry” method is used, in which the compositions are exposed in a low humidity chamber to an atomized mix containing a liquid composition, where the chamber is subsequently exposed to approximately 80-110° F. to dry the liquid, thereby impregnating a material of the composition with the components. In some cases, Bacillus coagulans bacteria in the form of a spray-dried powder is included in or on the surface of the compositions described herein.
The active ingredients (i.e., live bacteria or extracellular components), comprise between about 0.01% to about 10%; 0.01% to about 1%; or about 0.05% to about 0.1% by weight of the probiotic composition. Optionally, the isolated Bacillus coagulans comprise about 1 mg to about 10 mg; about 10 mg to about 1 g; or about 25 mg to about 75 mg by weight of the cosmetic composition.
In one aspect, the extracellular products of the lactic-acid producing bacteria or the lactic-acid producing bacteria themselves are incorporated into a microcapsule coating, using any micro-encapsulation process well-known in the art. The Bacillus coagulans or Bacillus coagulans extracellular product are packaged, or encapsulated, within another material in order to protect the bacteria from the surrounding environment. The capsules of the invention range in size from one-thousandth of a millimeter to seven millimeters.
The internal ingredients of the microcapsule are released from their shells in various ways, including mechanical rupture of the capsule wall, dissolution of the wall, melting of the wall and diffusion through the wall. Thus, micro-encapsulation provides additional protection to the isolated Bacillus bacterium or the extracellular product of the Bacillus bacterium during manufacturing and storage of the compositions of the invention. Physical methods of micro-encapsulation include pan coating, air-suspension coating, centrifugal extrusion, vibrational nozzle, and spray-drying. Chemical methods of micro-encapsulation include interfacial polymerization, in-situ polymerization, and matrix polymerization.
The invention is directed to the surprising discovery that the extracellular product of lactic acid-producing bacteria, particularly Bacillus species, reduces visible signs of aging. For example, the extracellular product of Bacillus coagulans improves skin hydration/moisturization, improves skin elasticity, reduces the appearance of fine lines and wrinkles around the eye area, and decreases the appearance of under-eye puffiness and dark circles. As described herein, the compositions are formulated in many configurations because the bacterium is present as a vegetative cell or as a spore, or both, depending on the species and form of the probiotic organism. Preferably, the extracellular product of the bacterium is utilized in the cosmetic compositions described herein.
Cosmetics are substances used to enhance the appearance or odor of the human body. Cosmetics include skin-care creams, lotions, powders, perfumes, lipsticks, eye and facial makeup, gels, deodorants, hand sanitizer, bath oils, bath salts, butters, and many other types of products. A subset of cosmetics is called “make-up,” which refers primarily to colored products intended to alter the user's appearance. The U.S. Food and Drug Administration (FDA) which regulates cosmetics in the United States defines cosmetics as: “intended to be applied to the human body for cleansing, beautifying, promoting attractiveness, or altering the appearance without affecting the body's structure or functions.”
Accordingly, the cosmetic compositions described herein include various skin care products. These include creams and lotions to moisturize the face and body which are typically formulated for different skin types, and treatment products to repair or hide skin imperfections (acne, wrinkles, dark circles under eyes, etc.). For each skin type, the correct types of products must be used in order to maintain healthy and attractive skin. Regular use of a suitable moisturizer benefits the skin, as it hydrates and prevents the dehydration of skin. Thus, the compositions described herein protect the skin against the drying influences of the environment, including the harsh effects of the sun, cold and heat. Oil free moisturizers are utilized for oily skins. Types of moisturizers include oil—in water emulsions and water-in-oil emulsions. For normal and combination skin, a water based moisturizer containing minimal oil is suitable. Sensitive and dry types of skin require moisturizers containing a high content of oil.
The cosmetic compositions described herein include natural or organic ingredients. All natural products contain mineral and plant ingredients, while organic products are made with organic agricultural products.
Bacillus coagulans Extracellular Product to Reduce Visible Signs of Aging
The compositions of the invention reduce visible signs of aging. Specifically, Bacillus coagulans extracellular products and Bacillus coagulans itself, e.g., Bacillus coagulans strain GBI-30 or BC30, ATCC Designation Number PTA-6086, improve skin hydration/moisturization, improve skin elasticity, reduce the appearance of fine lines and wrinkles around the eye area, and decrease the appearance of under-eye puffiness and dark circles.
Accordingly, compositions comprising Bacillus coagulans bacteria extracellular product and Bacillus coagulans itself are administered to reduce visible signs of aging. For example, the bacteria extracellular product is administered in an amount that reduces visible signs of aging in the subject compared to the signs of aging in the subject prior to the administration. In some cases, a subject comprising a visible sign of aging is identified prior to administration of the bacteria. Preferably, the bacteria extracellular product is purified.
Skin hydration is increased by at least 1% following the administration of Bacillus coagulans bacteria extracellular product, e.g., skin hydration is increased by at least 1%, at least 2%, at least 3%, at least 4%, at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or at least 99% following the administration of Bacillus coagulans bacteria extracellular product compared to the skin hydration in the subject prior to the administration of Bacillus coagulans bacteria extracellular product.
Skin elasticity is increased by at least 1% following the administration of Bacillus coagulans bacteria extracellular product, e.g., skin elasticity is increased by at least 1%, at least 2%, at least 3%, at least 4%, at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or at least 99% following the administration of Bacillus coagulans bacteria extracellular product compared to the skin elasticity in the subject prior to the administration of Bacillus coagulans bacteria extracellular product.
Fine lines and wrinkles are reduced by at least 1% following the administration of Bacillus coagulans bacteria extracellular product, e.g., fine lines and wrinkles are reduced by at least 1%, at least 2%, at least 3%, at least 4%, at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or at least 99% following the administration of Bacillus coagulans bacteria extracellular product compared to the quantity of fines lines and wrinkles in the subject prior to the administration of Bacillus coagulans bacteria extracellular product.
Under eye puffiness and/or under eye dark circles are reduced by at least 1% following the administration of Bacillus coagulans bacteria extracellular product, e.g., under eye puffiness and/or under eye dark circles are reduced by at least 1%, at least 2%, at least 3%, at least 4%, at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or at least 99% following the administration of Bacillus coagulans bacteria extracellular product compared to the under eye puffiness and/or under eye dark circles in the subject prior to the administration of Bacillus coagulans bacteria extracellular product.
The compositions of the invention comprise a skin aging-reducing amount of Bacillus coagulans bacteria extracellular product. For example, the Bacillus coagulans bacteria extracellular product is provided at a concentration of 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 15%, 20%, 25%, 35%, 50%, 60%, 75%, 90%, 99% or 100% in the cosmetic compositions described herein.
Exemplary formulations of the compositions of the invention include a suspension, a powder, a cream, a lotion, a salve, a gel, a scrub, a mask, a shampoo, and a conditioner.
The compositions of the invention are administered topically. The compositions are administered at least once per day, e.g., at least twice per day, at least 3 times per day, at least 4 times per day, or at least 5 times per day. Preferably, the compositions are administered for at least 24 hours, at least 48 hours, at least 72 hours, or for at least 7 days, at least 14 days, at least 30 days, at least 60 days, at least 90 days, or for at least 4 months, at least 6 months, at least 9 months, or for at least 1 year, at least 2 years, or at least 3 years.
In some embodiments, the composition modulates expression of a gene or a protein that affects transepidermal water loss, desquamation, epidermal barrier integrity, ceramide synthesis, or a combination thereof. In some aspects, the composition decreases transepidermal water loss. For example, the composition increases the expression of an aquaporin protein or a gene encoding an aquaporin protein, such as aquaporin 1 (AQP1). The expression level of a gene encoding an aquaporin protein can be measured by determining the level of the mRNA transcript and/or cDNA of the mRNA transcript or fragment thereof of the gene. The amino acid sequence of homo sapiens aquaporin 1 (AQP1) protein is shown below (NP—932766.1), incorporated herein by reference:
The mRNA sequence of homo sapiens AQP1 is shown below (NM—198098.2), incorporated herein by reference (the start and stop codons are underlined):
Also, the composition increases the expression of a structural protein or a gene encoding a structural protein, such as a collagen, e.g., Type 3 collagen is collagen Type 3, Alpha 1 (COL3A1). The expression level of a gene encoding a structural protein can be measured by determining the level of the mRNA transcript and/or cDNA of the mRNA transcript or fragment thereof of the gene. The amino acid sequence of homo sapiens collagen Type 3, Alpha1 (COL3A1) is shown below (P02452.5), incorporated herein by reference:
The mRNA sequence of homo sapiens COL3A1 is shown below (NM—000090.3), incorporated herein by reference (the start and stop codons are underlined):
Also, the composition increases epidermal barrier integrity, e.g., by increasing the level of expression of a cadherin protein or a gene encoding a cadherin protein. Cadherin proteins include desmocollin, cadherin, protocadherin, and desmoglein. In some embodiments, the cadherin protein comprises a desmocollin protein, e.g., desmocollin 1 (DSC1). The expression level of a gene encoding a cadherin protein can be measured by determining the level of the mRNA transcript and/or cDNA of the mRNA transcript or fragment thereof of the gene. The amino acid sequence of Homo sapiens desmocollin 1 (DSC1) is shown below (Q08554.2), incorporated herein by reference:
The mRNA sequence of Homo sapiens DSC1 is shown below (NM—004948.3), incorporated herein by reference (the start and stop codons are underlined):
In addition or alternatively, the composition decreases desquamation, e.g., by decreasing the expression of a kallikrein protein or a gene encoding a kallikrein protein, e.g., kallikrein 6 (KLK6). The expression level of a gene encoding a kallikrein protein can be measured by determining the level of the mRNA transcript and/or cDNA of the mRNA transcript or fragment thereof of the gene. The amino acid sequence of Homo sapiens kallikrein 6 (KLK6) is shown below (NP—002765.1), incorporated herein by reference:
The mRNA sequence of Homo sapiens KLK6 is shown below (NM—002774.3), incorporated herein by reference (the start and stop codons are underlined):
In addition, the composition increases ceramide synthesis, e.g., by increasing the level of expression of a sphingomyelin phosphodiesterase or a gene encoding a sphingomyelin phosphodiesterase, e.g., sphingomyelin phosphodiesterase 1 (SMPD1). The expression level of a gene encoding a sphingomyelin phosphodiesterase protein can be measured by determining the level of the mRNA transcript and/or cDNA of the mRNA transcript or fragment thereof of the gene. The amino acid sequence of Homo sapiens sphingomyelin phosphodiesterase 1 (SMPD1) is shown below (AAH41164.1), incorporated herein by reference:
The mRNA sequence of Homo sapiens SMPD1 is shown below (BC041164.1), incorporated herein by reference (the start and stop codons are underlined):
Bacillus coagulans Hammer bacteria (ATCC Accession No. 31284) was inoculated and grown to a cell density of about 108 to 109 cells/ml in nutrient broth containing 5 g Peptone, 3 g Meat extract, 10-30 mg MnSO4, and 1,000 ml distilled water, adjusted to pH 7.0, using a standard airlift fermentation vessel at 30° C. The range of MnSO4 acceptable for sporulation is 1 mg/l to 1 g/l. The vegetative cells can actively reproduce up to 45° C., and the spores are stable up to 90° C. After fermentation, the B. coagulans bacterial cells or spores are collected using standard methods (e.g., filtration, centrifugation) and the collected cells and spores can be lyophilized, spray-dried, air-dried, or frozen. The supernatant from the cell culture is collected and used as an extracellular agent secreted by B. coagulans.
A typical yield from the above culture is in the range of about 109 to 1010 viable spores and more typically about 100 to 150 billion cells/spores per gram before drying. Spores maintain at least 90% viability after drying when stored at room temperature for up to ten years, and thus the effective shelf life of a composition containing B. coagulans Hammer spores at room temperature is about 10 years.
A culture of dried B. coagulans spores was prepared as follows. Ten million spores were inoculated into a one liter culture containing 24 g potato dextrose broth, 10 g of enzymic-digest of poultry and fish tissue, 5 g of FOS and 10 g MnSO4. The culture was maintained for 72 hours under a high oxygen environment at 37° C. to produce culture having about 150 billion cells per gram of culture. Thereafter, the culture was filtered to remove culture medium liquid, and the bacterial pellet was resuspended in water and freeze-dried. The freeze-dried powder is then ground to a fine powder using standard good manufacturing practice (GMP).

A human clinical trial using the supernatant-containing formulation was conducted using 24 female subjects, ages 35-60. Skin condition at baseline, after using active formula, and after using placebo was evaluated.
At 4 weeks, the cream plus supernatant increased skin hydration by 7.13% more than a placebo cream, while the cream plus supernatant increased skin elasticity by 3.11% more than a placebo cream. Off the silicone replicas, the cream plus supernatant decreased the number of coarse skin lines by 20.57% more than a placebo cream, while the cream plus supernatant increased skin smoothness by 4.33% more than a placebo cream. The cream plus supernatant decreased skin shadows by 7.09% more than a placebo cream. Off of visual evaluation, the cream plus supernatant had 17% increase in the number of subjects showing improvement of eye area fine lines and wrinkles more than a placebo cream, while the cream plus supernatant had 8.33% increase in the number of subjects showing improvement of under eye puffiness more than a placebo cream.
The results are summarized below.

The use of moisturizers affects the water content of the outermost layers of skin, i.e., the stratum corneum (SC) (Jemec G B, Serup J. Epidermal Hydration and Skin Mechanics Acta Derm. Venereal.: 70: 245-250 (1990)). Changes in skin conductance, impedance or capacitance are used to study epidermal hydration in vivo. The measurement is made on the difference in dielectric constant; skin has a low dielectric constant and water has a high dielectric constant of 81. When skin is hydrated, conductance and capacitance increases and impedance decreases. The measuring capacitor shows changes in capacitance according to the moisture content of the tissue. A glass lamina separates the metallic tracks in the probe head from the skin in order to prevent current conduction in the tissue. An electric scatter field penetrates the skin during the measurement and the dielectricity is determined
Corneometer CM 825 (Courage+Khazaka Electronic GmbH, Köln, Germany) was used to measure the electrical capacitance of the skin.
The biomechanical properties of human skin are a complex combination of elastic (elastin fibers) and viscous (collagen fibers and surrounding intercellular ground substance) components. The Cutometer allows the measurement of the viscoelastic properties of the skin in vivo. See, Undine B, Elsner P. Hardware and Measuring Principle: The Cutometer. In the Bioengineering of the Skin—Skin Biomechanics 2002; Pp 91-98; and Agache P, Varchon D. Skin Mechanical Function. In the Measuring the Skin. 2004; Pp 429-467, each of which is incorporated herein by reference. The measuring principle of the Cutometer is based on suction. A defined negative air pressure is created and applied on the skin surface through the opening of a probe drawing the skin into its aperture. The resulting vertical deformation of the skin is measured by determining the depth of skin penetration into the probe. This is achieved by a noncontact optical system consisting of a light transmitter and a light recipient. Two glass prisms project the light from transmitter to recipient, where the diminution of the infrared light beam depending on the penetration depth of the skin is measured.
Cutometer MPA 580 (Courage+Khazaka Electronic GmbH, Köln, Germany) was used to measure skin elasticity.
This was achieved by obtaining a topical 3D micro-anatomical profilometry via silicon replicas. See, Skin Res. Technol., 2: 112-117, 2002. Generally, sites evaluated for fine lines and wrinkles include the periocular areas located on the side of the eyes (Crow's feet) Two (2)×two (2) cm adhesive templates were affixed to the test site and Replifo vinyl silicone (Cuderm Corporation, Dallas, Tex.) was dispensed onto the template demarcated areas. After ˜5 minutes, the replicas were cured and gently removed from the skin surface. Image analysis using a Cohu solid state B&W camera, 50 mm lens/30 mm extension, Coreco TCI Ultra frame grabber interfaced with an IBM compatible PC is conducted by Cuderm Corporation, Dallas, Tex.
Specifically, during the image analysis phase, a collimated light source was directed at a 25-degree angle from the place of the replica. The replica was gently placed in the holder and was rotated to align for normal or parallel exposure to the incident light direction. Further changes in the gradient of light intensity can produce changes in luminance, which in turn is used to assess changes in skin roughness displayed by the replica. The normal sampling orientation provides texture measurements sensitive to the major expression-induced lines and the parallel sampling orientation provided texture measurements sensitive to the minor fine lines.
The shadow texture produced by the oblique lighting of the negative replica is analyzed by two types of assay methods:
1) Measuring the luminance along a set of 10 equal length parallel lines running across the replica parallel to the lighting direction. The variance in luminance are treated as indicative of the roughness and analyzed by traditional surface roughness statistics.
2) The replica image area is divided into 10 equal width bands and the shadow like features are detected according to their luminance values.
The 8 wrinkle texture parameters measure various aspects of the image produced by the replica surface: Rz and Ra=skin roughness texture; IDL=increases with roughness of the surface; FNum=number of markers indicative of fine and coarse lines per mm; Spacing=mean distance between adjacent strong shadow features; Breadth=proportional to the depth of the wrinkle producing the shadow; Shadows=relative area of shadows cast by all the wrinkles and fine lines; and NumWr=total number of shadowy features available to calculate spacing and breadth.
Photographs were taken in accordance with regulations provided by consumer protection agencies such as the Federal Trade Commission, the Food and Drug Administration and several other regulatory authorities. The following guidelines were followed: 1) Head position was the same in before and after photos, 2) Same lighting conditions were used and the distance from the camera was same for both, before and after picture, and 3) Same room and background was used for both before and after picture.
Clinical photographs of subjects' faces (frontal, left lateral and right lateral) were taken with Canfield VISTA CR system using parallel polarized mode and UV mode.
Photographs obtained were evaluated for fine lines/wrinkles around the eye areas, under-eye dark circles and under-eye puffiness by a descriptive scale for Evaluation of Photodamage according to the R. W. Johnson Pharmaceutical Research (Griffiths et al., 1992 Arch Dermatol, 128(3): 347-351, incorporated herein by reference) Scale 7-9 listed below: Overall Rating Scale: 0=None, 1-3=Mild, 4-6=Moderate, 7-9=Severe.

As described below, the effect of drying and subsequent rehydration of Bacillus coagulans (BC) supernatant and cell wall fractions, as well as further fractionation based on molecular weight ranges was examined. As described in detail below, gel electrophoresis was performed to compare the crude preparations of BC cell wall and supernatant fractions. Moreover, three different molecular weight ranges from supernatant and cell wall fractions were evaluated in selected bioassays to identify which compounds may be associated with biological activity. The effect of crude cell wall and supernatant fractions of BC on dendritic cell maturation was examined. Finally, as described in detail below, it was determined if selected key biological activities of the BC supernatant and cell wall fractions is preserved after drying and rehydration.
Described herein are anti-inflammatory compound(s) present in the high molecular weight fraction (30-200 kDa) of BC30. As described below, both high- and low-molecular weight immune modulating compound(s) present in BC30 fractions activate NK cells. Additionally, compounds, particularly compounds in the metabolite fraction, trigger induction of IL-6 and TNF-alpha.
As described below, drying and reconstituting Bacillus coagulans extracellular product (metabolites/supernatant) results in unexpected anti-inflammatory effects. Drying the Bacillus coagulans extracellular product (metabolites/supernatant) inactivated or removed undesirable compounds (e.g., volatile organic compounds) that would otherwise inhibit the anti-inflammatory effects of the Bacillus coagulans extracellular product. For example, drying and reconstituting the Bacillus coagulans extracellular product results in at least 1% greater anti-inflammatory activity compared to Bacillus coagulans extracellular product alone, e.g., at least 2%, at least 3%, at least 4%, at least 5%, at least 6%, at least 7%, at least 8%, at least 9%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or at least 99% greater anti-inflammatory activity compared to Bacillus coagulans extracellular product alone.
The test fractions of Bacillus coagulans (BC30) supernatant (metabolites fraction) and cell wall were prepared as follows. A sample of Bacillus coagulans spores was heat-activated at 50° C. and inoculated in liquid culture medium. The sample was incubated at 37° C. for 24 hours at which time additional media was added followed by incubation at 37° C. for an additional 24 hours. This time period allowed the formation of a log-phase bacterial culture where death and bacterial breakdown was not prominent. After the incubation, the two fractions (Bacillus coagulans supernatant (BC1) and Bacillus coagulans cell wall components (BC2)) were prepared. The initial separation occurred by decanting the entire culture into a 50 mL vial followed by centrifugation at 2400 rpm. This resulted in the bacteria forming a pellet. The supernatant was gently decanted into a new vial. From this vial, smaller 1 mL samples were aliquoted into Eppendorf vials and subjected to high speed centrifugation, followed by two serial filtrations with a 0.2 um filter, to eliminate any intact bacteria and fractions thereof. The sterile, filtered supernatant was aliquoted and multiple aliquots frozen and stored at −20° C. For later biological assays, one aliquot was thawed on each testing day.
The original pellet from the initial centrifugation was used to prepare the cell wall fraction. The bacterial pellet was washed twice with physiological saline, and the wet pellet was frozen and thawed several times to break open the bacterial walls so that the intracellular compounds could be removed by washing. The thawed slush was transferred to a glass vial and subjected to multiple rounds of bead milling using low-protein-binding Zirconium beads with a diameter of 100 micrometer. The milling was performed by repeated ‘pulsing’ using a Vortex mixer. This method is effective to break up cell walls of bacteria and cyanobacteria. The beads were removed and the slush containing the broken cell wall fragments were sterile-filtered into multiple aliquots that were frozen immediately and stored at −20° C. For later assays, one aliquot was thawed on each testing day. Similar volumes of Bacillus coagulans cell wall or supernatant were placed into centrifugation columns that filter out specific molecular weight fractions. After centrifugation, the remaining volumes were serial diluted and used in downstream bioassays.
In order to identify the molecular weights of predominant protein/carbohydrate compounds in the supernatant and cell wall fractions of BC, electrophoresis was used to understand the protein and polysaccharide makeup of BC30 (GBI-30/GB-30/Ganeden BC30™/BC30, ATCC Designation Number PTA-6086) fractions and spores. Crude BC cell wall and supernatant (extracellular product/metabolite) fractions were further separated into three different size ranges using molecular weight cutoff filters.
A typical protein gel electrophoresis method is shown in
Gel electrophoresis of the previous batch of supernatant and cell wall fractions showed several regions of interest. The supernatant contained compounds lower than 5-10 kDa, i.e., lower than the range that can be clearly fractionated by SDS gel electrophoresis (see, smear below the words “BC Supernatant” in
Fractionation of the BC30 crude supernatant (metabolites) and the crude cell wall fraction was carried out to yield three fractions or purified preparations A) below 3 kDa, B) between 3-30 kDa, and C) between 30-200 kDa. The major bioactive compounds from the cell wall are in fraction B. Electrophoresis is used as a tool to ensure product consistency during stages of product development. It is also useful as a regular quality control tool during manufacturing.
As shown in
As described in detail below, size fractionation by molecular weight (<3, 3-30, 30-200 kDa) of both supernatant and cell wall fractions was performed to further characterize the following three biological activities: a) Anti-inflammatory effect, as measured by inhibition of cell migration in response to inflammatory mediators; b) Effect on NK cell activation; and c) Effect on cytokine production.
The polymorphonuclear leukocyte (PMN) cell is a highly active and migratory cell type. Bacillus coagulans fractions have strong anti-inflammatory effects when exposed to the known inflammatory cytokine leukotriene B4 (LTB4). Crude BC30 cell wall and BC supernatant were fractionated into the following molecular weight ranges: a) <3 kDa, b) 3-30 kDa, and c) 30-200 kDa, and LTB4-directed migration was examined. Similar volumes of Bacillus coagulans cell wall and supernatant were placed into centrifugation columns that filter out specific molecular weight fractions. After centrifugation, the remaining volumes were serial diluted and placed in with the PMN's before plating into the top chamber.
As described below, the repeat experiments were performed using primary immune cells from three different blood donors. In the last of these 3 experiments, an additional test was included, where crude cell wall and supernatant fractions were allowed to dry, then were reconstituted to the original sample volume. The bioactivity and dose response were tested in comparison to the non-dried cell wall and supernatant fractions in order to identify if drying and reconstitution affects biological activity in key assays.
Freshly purified PMN cells cultures were set up in double-chamber migration plates, where the bottom chamber mimics tissue, and the top chamber mimics the blood stream as described in
As shown in
Thus, it is concluded that potent anti-inflammatory compounds exist in the high molecular weight fraction of both the supernatant (metabolites) and cell wall of Bacillus coagulans.
The difference between a reconstituted sample and a normal, non-dried sample was evaluated. An aliquot of crude BC metabolites and crude BC cell wall were each allowed to evaporate under sterile conditions followed by reconstitution to their original volume with sterile water. These samples were then compared to crude metabolites and crude cell wall that had not undergone the drying and reconstitution steps.
As shown in
Thus, drying and reconstitution unexpectedly increased the anti-inflammatory effect of both the supernatant (metabolites) and cell wall (CW) fractions, which was likely due to the inactivation of small compounds (<30 kDa). Moreover, the results demonstrate that the anti-inflammatory compounds present in Bacillus coagulans supernatant and cell walls are stable after drying and rehydration, which property is useful in the large scale production of these fractions.
Crude BC30 cell wall and BC supernatant (metabolite) were fractionated into the following molecular weight ranges: a) <3 kDa, b) 3-30 kDa, and c) 30-200 kDa. Both BC fractions activated NK cells. Induction of the CD69 activation marker on the NK cells was determined in order to identify in which fractions most activity is observed.
Freshly purified human peripheral blood mononuclear cells were used for these assays. The cells are plated in 96-well micro-assay plates in duplicate. Negative control wells in quadruplicate were left untreated. Positive controls were treated with interleukin-2 (IL-2) at a dose of 100 international units per mL (IU/mL). After 18 hours of culture, cells were stained for the activation molecule CD69 on the surface of CD3-negative, CD56-positive NK cells. In this manner, the direct activation of NK cells is examined in vitro.
As shown in
Metabolites (supernatant): Crude metabolites demonstrated a dose dependent response, and the 3 highest doses resulted in highly statistically significant increases in CD69 expression (P<0.01). This increase in CD69 expression on NK cells by crude metabolites was mirrored by the 30-200 kDa fraction while the 3-30 kDa and <3 kDa fractions increased CD69 expression to much lesser degrees. Examining the effects of the individual metabolite fractions, synergy between large and small compounds both activating NK cells allows the crude preparation to work the best.
Cell Wall Crude cell wall increased NK cell CD69 expression at all 4 doses tested (P<0.05), and an identical result was seen with the 30-200 kDa cell wall fraction. Conversely, the 3-30 kDa and <3 kDa cell wall fractions did not change NK cell CD69 expression from baseline levels. It is clear with the cell wall preparations that it is large compounds that are having an effect.
These results demonstrate that both large and small molecular weight compounds present in the metabolite preparation are capable of activating NK cells, while in the cell wall preparation, the large molecules are responsible for activating NK cells.
Biological activity of Bacillus coagulans supernatant and cell wall components was also assessed after drying and reconstitution to determine if bioactivity is preserved after drying. As shown in
Crude BC cell wall and BC supernatant were fractionated into the following molecular weight ranges: a) <3 kDa, b) 3-30 kDa, and c) 30-200 kDa. The effect of the crude and size-fractionated BC30 preparations on lymphocyte proliferation was examined.
As shown in
Previous experiments showed that the BC fractions directly induced changes in cytokine production. The fractions were examined to identify which molecular weight ranges of compounds in the BC supernatant and cell wall fractions are responsible for this change. Freshly purified human peripheral blood mononuclear cells (PBMC) were cultured for four days in the absence versus presence of serial dilutions of BC fractions. Supernatants from these cultures were then used to examine changes in cytokine production. Biological activity of Bacillus coagulans supernatant and cell wall components is also assessed after drying and reconstitution to determine if bioactivity is preserved after drying. The BD BioSciences cytokine bead array for flow cytometry was utilized to simultaneously measure levels of IL-2 (
Metabolites (BC30 supernatant): IL-2, IL-10 and IFN-γ did not show significant changes from untreated cells. IL-4 levels were slightly increased by the crude metabolite and 30-200 kDa metabolite fractions. IL-6 levels were highly increased by all fractions, and there was synergy of different sized molecules as indicated by the largest increase being observed with the crude fraction. TNF-alpha levels were increased by crude as well as all fractions.
Cell Wall: IL-10 and IFN-γ did not show significant changes from untreated cells. IL-2 and IL-4 levels were reduced by all cell wall fractions. IL-6 levels were greatly increased by both crude cell wall and the 30-200 kDa fraction; however, the fractions containing small compounds (<3 kDa and 3-30 kDa) had no effect. TNF-alpha levels were increased by crude cell wall as well as all fractions, but to a lesser extent than metabolites.
Thus, the results show some differences in the effects of individual fractions on cytokine production, as well as differences between the BC30 metabolites and cell wall fractions.
Probiotics and commensal bacteria interface with the mucosal immune system in the gastrointestinal tract. Dendritic cells play a major role in this interaction, and there is a direct effect of probiotics on dendritic cell biology. This includes effects on dendritic cell maturation and cytokine production.
Dendritic cells (DC) are immune cells that play an important role in both adaptive and innate immunity through their function as professional antigen presenting cells (adaptive immunity) and the generation of the type 1 interferons alpha and beta during viral infection (innate immunity). Dendritic cells circulate in the blood and are also present in environmental contact sites such as the skin and mucosal linings of the nose, lungs, stomach and intestines. Dendritic cells can be separated into different types based on expression of cell surface markers including Toll-like receptors (TLR) and by their anatomical location.
Dendritic cell maturation: Immature dendritic cells in the blood and mucosa interact with pathogens such as viruses and bacteria through toll-like receptor molecules on their surface. The recognition of antigen by immature dendritic cells results in their maturation and migration to lymph nodes where they interact with T and B cells and initiate an adaptive immune response. The maturation of dendritic cells involves the expression of a number of cell surface proteins. This maturation process can be monitored through the use of fluorescently-labeled antibodies to these cell surface proteins combined with flow cytometry. Two cell surface proteins that increase in expression during the maturation of dendritic cells are CD80 and CD86.
Dendritic cells also play a role in the development of tolerogenic/regulatory T cells that prevent the body from mounting an immune response to a particular antigen. This is an important process in the development and maintenance of immune recognition. When this recognition goes wrong, it can be seen either as wrongful self recognition such as in autoimmune disease or wrongful recognition of harmless antigens such as in allergic reactions. It may also be seen as a lack of recognition such as in immunological anergy (unresponsiveness) such as what can be involved in the development and progression of cancer.
Freshly purified human peripheral blood mononuclear cells were used for the assays described below. The cells were plated in 96-well micro-assay plates in duplicate. Negative control wells in quadruplicate were left untreated. Positive controls in triplicate were treated with LPS. Following a 3 day incubation, cells were harvested and stained with fluorescently-labeled antibodies to maturation markers. Initial staining used the combination of CD14, CD80 and CD86. The assay was repeated 3 times using cells from 3 different blood donors. These experiments on the effects of BC on dendritic cell biology was performed with BC30 crude metabolites and crude cell wall.
Part of the assessment of effects on monocytes and dendritic cells involved staining for the CD14 cell surface receptor. This is a bacterial pattern recognition receptor, also involved in recognition of lipopolysaccharide (LPS) present in the cell wall of gramnegative bacteria.
At all dilutions tested, both crude metabolites and cell wall increased the percentage of cells expressing CD14 (
Both crude metabolites and cell wall demonstrated a dose-dependent effect on increasing the expression of CD14 on CD14+ cells (monocyte population;
Both crude metabolite and cell wall fractions treatment of PBMC led to a decrease in CD80 expression on the cell surface of CD14+ cells (
The effect of crude metabolites on CD86 expression on CD14+ cells showed an interesting dose-dependent response where the greatest reduction resulted from the lowest dose (
The loss of CD80 and CD86 expression on CD14+ in combination with the increase in CD14+ cells indicates that dendritic cells are differentiating into a monocytoid phenotype.
The purpose of this placebo-controlled study was to evaluate the performance of an anti-aging product when tested over a 4 week period in a randomized, open labeled double-blind test design. As described in detail below, wrinkle assessment was conducted instrumentally using a Visioscan image analysis system. Elasticity and viscoelastic properties of the skin were measured as a function of flexibility and firmness employing a Cutometer. Retained water content of the skin was measured using the Nova Dermal Phase Meter.

Number of subjects enrolled: 10
Number of subjects completing study: 10
Ten healthy females were inducted into this study. The samples—Active and Placebo—were randomized and numbered (from 1 to 10). All test products appeared identical to placebo to protect the study blind. At the completion of the study, upon the receipt of the data, the decoding table of random sampling numbers (including the sample description) was used for the purpose of statistical analysis and data reporting.
As a condition of enrollment, only the subjects who were currently not using any anti-aging products, and who have abstained from using them for at least 30 days prior to study commencement were recruited for participation in this investigation. On the initial day of the study, upon arrival at the testing facility, subjects were required to familiarize themselves with and sign the informed consent. Subjects were mandated to adhere to all the restrictions mentioned in the inclusion/exclusion section. All participants were advised of the general nature and purpose of this study. The subjects then acclimated to the ambient environment for a period of thirty minutes prior to baseline evaluation. The same acclimation procedure was applied to any following evaluation time point.
All 10 participants of the study received the test product. Neither the investigator nor the test subjects were aware if they received an active product or placebo. Prior to baseline measurements were taken, areas of involvement were marked on the facial surface using a standard template, to ensure that instruments were repositioned in the same place at each visit. As described in detail below, all biophysical measurements (Skin Moisturization—Electroconductivity via Novameter, Surface Evaluation of Living Skin via Visioscan and Skin Elasticity via Cutometer) were conducted by a trained technician, and Pre-treatment High Resolution Scientifically Matched Photographs were taken.
Panelists received verbal and written instructions regarding product use and study restrictions. Subjects were required to use the test product as a part of their daily routine according to the following instructions: “Use twice daily. On a clean, dry skin, apply cream to forehead, eye area and cheeks. Rub product in completely as appropriate. Apply usual make-up as needed.”
After 14 and 28 days of daily use of the test product, test subjects were re-evaluated. After acclimating to ambient conditions, the measurements (Skin Moisturization—Electroconductivity via Novameter, Surface Evaluation of Living Skin via Visioscan and Skin Elasticity via Cutometer) were repeated using the standard template to identify sites on the face and, High Resolution Scientifically Matched Photographs were taken. Specifically, the following distinct noninvasive methods were employed to establish evaluation parameters.
A Nova Dermal Phase Meter, Model DPM 9003 (Nova Technology Corp., Gloucester, Mass.) was used to obtain measurements of skin surface impedance to determine electroconductivity of the treatment sites. The DPM 9003 is a portable, multifunctional electronic laboratory instrument that measures skin impedance, and was designed to provide a non-invasive, objective, reproducible method of measurement to quantify biophysical characteristics and relative hydration of the skin. This meter provides a relative measure of the retained water content of the skin as a function of the skin's dielectric value. The Nova Dermal Phase Meter (DPM) is used in the art as an impedance-based instrument using capacitive reactance values expressed in arbitrary DPM units.
Specifically, as described in Clarys et al., 1999 Skin Research and Technology, 5: 14-20 (“Clarys,” incorporated herein by reference), the Nova DPM 9003 (Nova Technology Corporation) measures impedance based capacitive reactance of the skin at preselected frequencies up to 1 MHz from the observed signal phase delays. The standard 8 mm probe features (0.9 cm2 surface) two concentric brass ring electrodes separated by an isolator (with respective inner and outer diameter of 4.34 and 8.76 mm). The distance between the inner and the outer electrode is 1 mm. There is direct galvanic contact between the electrodes and the skin. By integrating measurements at the preselected frequencies, capacitive reactance is calculated from the signal and phase delay using an integrated circuit in the instrument. The final readout is given in arbitrary DPM units, ranging from 90 to 999 DPM units, which are directly related to the capacitance. An automatic calibration takes place, ensuring standardization of the instrument before taking any readings.
Clarys also describes other instruments used in dermato-cosmetic research, including the Corneometer CM 825 (Courage+Khazaka Electronic GmbH, Köln, Germany) and the Skicon-200 (ISBS Co, Hamamatsu, Japan).
Skin impedance was recorded automatically when equilibrium was achieved. See, Leveque and de Rigal, 1983 J. Soc. Cosmet. Chem., 34: 419-428, incorporated herein by reference. As shown in Table 43 below, Novameter readings demonstrated that the test product M-7293 (i.e., cream with 5% Bonicel (Bacillus coagulans supernatant) dramatically increased the skin moisture content. The increases are considered statistically significant after 14 and 28 days of use (
As shown in Table 44 below, Novameter readings demonstrated that the test product M-7294 (i.e., cream without Bonicel (Bacillus coagulans supernatant) did not increase the skin moisture content (
A summary of the Novameter readings for each of the two groups (i.e., with and without Bonicel) is provided in Table 45 below.
The Visioscan, e.g., Visioscan® VC 98, (Courage+Khazaka Electronic GmbH, Köln, Germany) takes a direct image of the living skin using a measuring head containing a CCD-camera featuring a high resolution video sensor and two metal halogen lamps positioned opposite each other in order to ensure even/uniform illumination of the measuring field on the skin. The resulting images are displayed in 256 gray levels. The grey level distribution of the pixels in the image correspond to different phenomena (white pixels represent desquamation/scaliness on the skin, dark pixels represent lines and wrinkles). The software analyzes the gray level distribution and calculates four clinical parameters to quantitatively and qualitatively describe the skin surface as an index: skin smoothness, skin roughness, scaliness and wrinkles. See, Fischer et al., 1999 Skin Pharmacol Appl Skin Physiol, 12: 1-11; Farwick et al., 2009 An EC-derived Tetrapeptide to Counterbalance ECM Degeneration; Cosmetic & Toiletries magazine, Vol 124 Np. 6/June, each of which is incorporated herein by reference.
As shown in Table 46 below, within the limits imposed by the conduct and population size of the placebo-controlled study, the anti-aging test material (AMA Lab No.: M-7293 (Cream with 5% Bonicel (Bacillus coagulans supernatant), Lot 28378) demonstrated a dramatic decrease compared to placebo treatment (AMA Lab No.: M-7294 (Cream without Bonicel, Lot 28378) in the Visioscan parameters of surface roughness (SEr) associated with the depth of fine and course wrinkles. The reductions were considered statistically significant after 28 days of use (
As shown in Table 47 below, Visioscan readings demonstrated that the test product M-7294 (i.e., cream without Bonicel (Bacillus coagulans supernatant) did not decrease surface roughness associated with the depth of fine and course wrinkles (
A summary of the Visioscan readings for each of the two groups (i.e., with and without Bonicel) is provided in Table 48 below.
A Cutometer SEM 575 (Courage+Khazaka Electronic GmbH, Köln, Germany) was used to measure skin viscoelastic properties. The Cutometer dual MPA 580 (Courage+Khazaka Electronic GmbH, Köln, Germany) is also a suitable tool to measure skin viscoelastic properties. The measuring principle is based on a suction method. Negative pressure is created in the device, which can be regulated between 20 and 500 mbar. Skin is drawn into a calibrated aperture of the probe by negative pressure and after a defined time, released again. Inside the probe, the skin penetration depth is determined by a non-contact optical measuring system. The optical measuring system consists of a light transmitter and a light recipient, as well as two glass prisms facing each other, which project the light from transmitter to recipient. The light intensity will vary due to the penetration depth of the skin. The resistance of the skin to the negative pressure (firmness) and its ability to return into its original position (elasticity) are displayed as curves (penetration depth in mm/time) in real time during the measurement. This measurement principle allows for obtaining information about the elastic and mechanical properties of skin surface and enables the objective quantification of skin aging. Well-established elasticity parameters, including firmness, resistance to suction, and fatigue can be determined. See, Agache et al., 1980 Arch. Dermatol. Res., 269: 221; de Rigal and Leveque et al., 1985 Bioeng. Skin, 1: 13, each of which is incorporated herein by reference.
As shown in Table 49 below, evaluation of the skin's Elasticity/Flexibility via Cutometer demonstrated an increase in biological elasticity in the group treated with the test product M-7293 (i.e., cream with 5% Bonicel (Bacillus coagulans supernatant)) after 14 and 28 days (
As shown in Table 50 below, evaluation of the skin's Elasticity/Flexibility via Cutometer did not demonstrate an increase in biological elasticity in the group treated with the test product M-7294 (i.e., cream without Bonicel (Bacillus coagulans supernatant) (
A summary of the skin elasticity readings for each of the two groups (i.e., with and without Bonicel) is provided in Table 51 below.
Exclusively detailed, high resolution before and after digital photographs were taken, with fixed camera background, distances, angles, settings, lighting, panelist positioning, color bars, white balance, standardized and digitally certified unretouched (AMA Laboratories, Inc., NY, N.Y.). Each stage in the progression of the treatment regimen was photographically documented and the test area of involvement isolated. Photographs were evaluated using image analysis software which allows the evaluation parameter (e.g., wrinkles) to be captured and quantified. Image analysis software detects subtle changes in color by three dimensional profile of hue, value and chroma. These characteristics are then translated into color coordinates (a*, b* and L*) whose spacing is considered with the color changes perceived by the human eye. The size of the area of involvement differs for each test panelist. Therefore, percent difference is calculated individually and then averaged. [px2]—wrinkle related pixels per area of involvement. Suitable dermatological image software analysis programs include, e.g., Mirror™ software (Canfield Scientific Inc. Fairfield, N.J.), 3D LifeViz™ (Quantificare Inc., San Mateo, Calif.), and Sculptor 3D simulation (Canfield Scientific Inc. Fairfield, N.J.).
Student's t-test was used for statistical analysis. This is the test of the null hypothesis that the difference between two responses measured on the same statistical unit has a mean value of zero. The changes in wrinkle size (area affected by wrinkle measured in px2) before and after the treatment were measured. If the treatment is effective, the area affected by wrinkle for the subjects is smaller following the treatment. This is often referred to as the “paired” or “repeated measures” t-test. Dependent samples (or “paired”) t-tests typically consist of a sample of matched pairs of similar units, or one group of units that has been tested twice (a “repeated measures” t-test).
As shown in Table 52 below, data obtained through image analysis software demonstrated wrinkle reduction after 14 and 28 days of usage of the test product AMA Lab No.: M-7293 (i.e., cream with 5% Bonicel (Bacillus coagulans supernatant). Each stage in the progression of the treatment regimen was photographically documented, and the test area of involvement was isolated. Photographs were evaluated using image analysis software which allows the wrinkles to be captured and quantified. The size of the area of Involvement differed for each test subject. Therefore, the percent difference was calculated individually and then averaged. [px2]—wrinkle related pixels per area of involvement. The results are considered statistically significant (
As shown in Table 53 below, data obtained through image analysis software demonstrated no improvement in wrinkle reduction after 14 and 28 days of usage of the test product AMA Lab No.: M-7294 (Cream without Bonicel, Lot 28378;
A summary of the wrinkle and fine lines reduction analysis for each of the two groups (i.e., with and without Bonicel) is provided in Table 54 below.
Studies were performed to determine the effect of Bonicel (Bacillus coagulans supernatant) at a concentration of 5% (v/v) on gene expression. In vitro full thickness skin cultures were treated with either 5% Bonicel or water (as a negative control). The linear fold-change in gene expression level was determined for the 5% Bonicel-treated cultures relative to water-treated cultures. A positive fold-change indicates that Bonicel increased the gene expression level relative to the water control. A negative fold-change indicates that Bonicel decreased the gene expression level relative to the water control. Linear fold changes above 2.0 (i.e., either decreased, −2.0, or increased, 2.0) were considered biologically significant. The expression of at least five genes was affected by Bonicel, as shown in Table 55.
Bonicel affected the expression level of genes involved in hydration and barrier integrity, e.g., AQP1, DSC1, KLK6, and SMPD1. AQP1 is a water channel molecule located on many cell types, e.g., skin cells. It plays a major role in regulating transcellular water transport. In the skin, aquaporin expression is associated with transepidermal water loss (TEWL). Several AQPs have been identified in the skin, including AQP1. While there is a large amount of research describing the role of the glycerol transporter aquaporin 3 (AQP3) in the skin, less is known about AQP1. Decreased AQP3 expression is associated with intrinsic and extrinsic aging of the skin, as well as a variety of skin diseases. Bonicel increased the level of expression of AQP1.
Desmocollins, e.g., DSC1, are calcium dependent cadherins that regulate cell-cell adhesion of desmosomes. DSC1 is required for strong adhesion and barrier maintenance in the epidermis and contributes to epidermal differentiation. A strong intact epidermal barrier is important for protecting the skin from environmental insults and preventing TEWL. Reductions in DSC1 expression level occur in aging skin. Bonicel increased level of expression of DSC1, which provides evidence that it promotes the maintenance of a healthy, epidermal skin barrier.
Kallikreins (KLK), e.g., KLK6, are serine proteases that play an integral role in the desquamation process, which is the shedding of the outermost membrane or layer of a tissue, such as the skin. Desquamation is a key factor in the stimulation of keratinocyte cell proliferation and differentiation. An appropriate balance of desquamation, i.e., sufficient but not excessive, is required for maintaining epidermal barrier formation and integrity. As skin ages, protein degradation and desquamation disequilibrium occurs. For example, excess protein degradation via an increase in KLK expression has been associated with intrinsic and extrinsic skin aging. Anti-aging products commonly affect cell renewal and turnover. Exposure of the skin cultures to Bonicel led to a decrease in the level of expression of KLK6, indicating that Bonicel balances protein degradation disequilibrium that occurs as the skin ages.
Acid sphingomyelinase, also known as sphingomyelin phosphodiesterase (SMPD), e.g., SMPD1, converts sphingomyelin into ceramide. Ceramides are lipids present in the stratum corneum, which is the outermost layer of the epidermis, consisting of dead cells that lack nuclei and organelles. Ceramides are important for maintaining skin moisture and a healthy epidermal skin barrier. Ceramide synthesis declines with aging and in response to harmful extrinsic stimuli, such as UV irradiation. Ceramide synthesis has been a focal point for anti-aging products, e.g., products that reduce the appearance of fine lines and wrinkles, for many years. This data shows a large increase in the amount of SMPD1 after exposure to Bonicel.
In addition, Bonicel affected the expression level of genes that encode structural proteins, e.g., collagen Type 3, Alpha 1 (COL3A1). COL3A1 is a structural protein produced by fibroblasts in the dermis and cells in the epidermal basement membrane. Type I and Type 3 collagens are the most prevalent connective tissue proteins in the skin. Reductions and disorganization of Type I and Type 3 collagen fibers is a characteristic of aged and photodamaged skin. This results in a loss of firmness and the appearance of wrinkles. Bonicel increased expression of COL3A1, providing support of its skin firming and anti-wrinkle activity.
In summary, treatment of full thickness in vitro skin cultures with 5% Bonicel produced statistically significant changes in genes related to hydration, epidermal barrier integrity and structural proteins. The most significant effect was the large induction of SMPD1 expression, the enzyme that produces ceramide.
A study was performed to evaluate two subjects given cream containing Bonicel (Bacillus coagulans supernatant) at a concentration (v/v) of 5%. Prior to treatment, the subjects had dry and cracked skin. The subjects applied cream containing 5% (v/v) Bonicel twice daily for at least 7 days. After 7 days, both subjects displayed a reduction in skin dryness. Images were taken of the subjects' skin before (
