This application contains a Sequence Listing that has been filed electronically in the form of an XML file, created Aug. 25, 2023, and named “PYH-00903 SL.xml” and is 542 KBs in size, the contents of which are incorporated herein by reference in their entirety.
The present disclosure relates to a peptide that is injected into the body of a subject to generate humoral immunity, which is a technology in the field of immunotherapeutics.
The purpose of an immunotherapeutic is to be introduced into the body of a subject to induce humoral immunity against the immunotherapeutic itself, and to thereby treat a specific illness or disease with the antibody produced as a result. In particular, the “treatment” also includes prevention of a specific illness or disease. Immunotherapeutics are similar to vaccines in that they induce antibody production through an antigen-antibody reaction in the body of a subject; however, they differ from vaccines in that the antibody has not only a binding ability to the immunotherapeutic itself, but also a binding ability to a specific target in the body (e.g., specific tissues and cells in the body, or substances generated in metabolic processes, etc.) thereby making it possible to treat a specific illness or disease, and administer repeatedly.
The present disclosure provides a peptide which has a function of inducing a pre-designed antibody in the body of a subject.

Hereinafter, the presently disclosed subject matter now will be described in more detail in terms of some specific embodiments and examples with reference to the accompanying drawings. It should be noted that the accompanying drawings encompass some, but not all embodiments of the present disclosure. The presently disclosed subject matter may be embodied in many different forms and should not be construed as limited to the specific embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Indeed, many modifications and other embodiments of the present disclosure will come to the mind of one skilled in the art to which the presently disclosed subject matter pertains. Therefore, it is to be understood that the presently disclosed subject matter is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims.
As used herein, the term “about” refers to a degree close to a certain quantity, and it refers to an amount, level, value, number, frequency, percent, dimension, size, amount, weight, or length that varies by to the extent of 30%, 25%, 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, or 0% with respect to a reference amount, level, value, number, frequency, percentage, dimension, size, amount, weight, or length.
As used herein, the term “peptide” refers to a polymer of amino acids. The term peptide refers to a form in which a small number of amino acids are linked, and is mainly used to distinguish it from a protein. There is no clear standard for distinguishing proteins from peptides, but as used herein, while about 200 amino acid polymers are referred to as peptides, those more than that are referred to as proteins, unless otherwise defined. The term “peptide” may include all other meanings recognized by those skilled in the art,
As used herein, the term “subject” refers to an organism that is an object exposed to a specific substance (e.g., peptide, etc.). The subject may refer to an independent organism (e.g., a human, animal, etc.) or may refer to a partial constitution of the independent organism (e.g., a part of a tissue, cell, etc.). This meaning may be appropriately interpreted according to the context. In addition, the term “subject” may further include all meanings recognized by those skilled in the art.
As used herein, the term “immunotherapeutics” is a concept distinguished from general therapeutics or vaccines. The immunotherapeutics are the same as existing vaccines in that they are injected into the body of a subject to induce a humoral immune response against the immunotherapeutics themselves. However, immunotherapeutics differ from existing vaccines in that the antibodies, which are induced as a result of the humoral immune response, have an ability being able to bind not only to the immunotherapeutics themselves, but also to specific tissues and cells in the body (e.g., receptors on the cell surface) or specific substances (e.g., peptides, lipids, proteins, and/or saccharides) produced during metabolism; thereby they can treat a specific illness or disease, and they can be administered continuously and repeatedly. Accordingly, the immunotherapeutics generally include antigens designed to induce antibodies having an ability to bind with a specific target tissue, cell, or substance in the body. Unless otherwise defined, the term “immunotherapeutics” is interpreted to include all antigens that can be appropriately used by those skilled in the art (e.g., peptides, proteins, lipids, saccharides, and/or complexes thereof, etc.) having the above-described functions. The term “immunotherapeutics” may be more limitedly referred to as “humoral-immunotherapeutics”. In addition, the term “immunotherapeutics” may include all meanings recognized by those skilled in the art.
As used herein, the term “treatment” collectively refers to any direct or indirect action or measure to eliminate, alleviate, reduce, inhibit, or improve the disease, illness, disorder, and/or symptoms of a subject, or any direct or indirect action or measure to induce the results of preventing the disease, illness, disorder, and/or symptoms. As used herein, the term “therapeutics” refers to various substances (e.g., compounds or peptides) that can exhibit the “treatment” effect when administered in an appropriate way to a subject. In addition, the term “treatment” or “therapeutics” may include all other meanings recognized by those skilled in the art.
As used herein, the term “immunogenicity” collectively refers to “the property of acting as an antigen capable of inducing an immune response” in the dictionary. There are various methods for measuring the immunogenicity of a specific antigen, and the methods may be appropriately adopted or designed according to the purpose. For example, the methods may include 1) a method for confirming whether IgG, IgA, and/or IgE type antibodies are generated in the body of a subject when the antigen is administered into the body of the subject, 2) a method for confirming the time when the IgG, IgA, and/or IgE type antibodies are generated depending on the administration cycle, 3) a method for confirming the titer of the induced antibodies to the antigen, and 4) when the mechanism of action of the induced antibodies is found, a method for measuring the effect according to the mechanism of action, but the methods are not limited thereto. The expression “increase of immunogenicity” may be used interchangeably with, for example, “increase of the effect of inducing an immune response”, “improvement of the ability to induce antibodies”, and “increase of the effectiveness as an immunotherapeutic”, and it includes all of the expressions which those skilled in the art can properly interpret according to the context.
As used herein, the term “mer” generally refers to the number of units in a high molecular weight polymer. As used herein, the term “mer” is generally expressed as “peptide with a length of an N mer” along % with a number when expressing the length of a peptide, which refers to a peptide in which a N number of amino acids are polymerized. The unit indicated by the expression “mer” should be properly interpreted within the context, and it includes all other meanings that can be recognized by those skilled in the art.
As used herein, the term “standard amino acid” refers to 20 amino acids synthesized through the transcription and translation processes of genes in the body of an organism. Specifically, the standard amino acid includes alanine (Ala, A), arginine (Arg, R), asparagine (Asn, N), aspartic acid (Asp, D), cysteine (Cys, C), glutamic acid (Glu. E), glutamine (Gin, Q), glycine (Gly, G), histidine (His, H), isoleucine (Ile, I), leucine (Leu, L), lysine (Lys K), methionine (Met, M), phenylalanine (Phe, F), proline (Pro, P), serine (Ser, S), threonine (Thr, T), tryptophan (Trp, W), tyrosine (Tyr, Y), and valine (Val, V). The standard amino acid has a corresponding DNA codon and can be represented by a general one-letter or three-letter notation of an amino acid. The subjects being referred to by the term standard amino acid should be appropriately interpreted according to the context, and they include all other meanings that can be recognized by those skilled in the art.
As used herein, the term “nonstandard amino acid” refers to an amino acid other than the standard amino acid. The nonstandard amino acid includes artificial and unnatural amino acids, and it includes those amino acids which are chemically modified through posttranslational modification within an organism, etc. The nonstandard amino acid includes, for example, D-form alanine, L-cyclohexylalanine, 6-aminohexanoic acid, etc. Since the nonstandard amino acid does not have a corresponding DNA codon, it cannot be represented by a general one-letter or three-letter notation of an amino acid, and it is written using other characters and explained via additional explanation. The subjects being referred to by the term nonstandard amino acids should be appropriately interpreted according to the context, and they include all other meanings that can be recognized by those skilled in the art.
Unless otherwise stated, when describing the sequence of a peptide in the present specification, single letter notation or three letter notation of an amino acid is used, and it is written in the direction from the N-terminus to the C-terminus. For example, when expressed as RNVP, it refers to a peptide in which arginine, asparagine, valine, and proline are sequentially linked in the direction from the N-terminus to the C-terminus. For another example, when expressed as Thr-Leu-Lys, it refers to a peptide in which threonine, leucine, and lysine are sequentially linked in the direction from the N-terminus to the C-terminus. In the case of amino acids that cannot be represented by the one-letter notation, other letters are used to describe these amino acids, and will be explained via additional explanation.
When expressing a peptide as a structural formula, N- and —C may be used to clearly indicate the N-terminus or C-terminus, and may be underlined so as to distinguish the N-terminus and/or C-terminus. For example, when the structural formula of a peptide is expressed as N-B-T-A-C, “N-” written at the beginning and “-C” written at the end are symbols to clarify the N-terminus and C-terminus directions unless otherwise specified. This refers to a peptide in which the sequences represented by B, T, and A are linked in the direction from the N-terminus to the C-terminus.
Among humoral immunities, an IgM-induced immune response is an innate immune function which is mainly active in the primary immune response, and it occurs rapidly in the early stages of infection. IgM is mainly secreted in the form of a pentamer, and theoretically has 10 antigen-binding sites, and thus, it can bind to a large number of antigens simultaneously. Although IgM can bind to a wide variety of types and forms of antigens and, the affinity and avidity of the binding are limited by the intrinsic affinity of IgM itself. Therefore, the affinity and avidity of IgM to an antigen are significantly lower than those of an antibody, such as IgG generated by the aid of helper T cells.
Although IgM-induced humoral immunity plays an important role in the initial immune response, the effect relying on humoral immunity by IgM is limited because 1) the production of IgM produced by B cells is low compared to those of other types of antibodies (e.g., IgG produced by differentiated B cells, etc.), 2) the specific binding ability of IgM to an antigen is low compared to that of IgG, and 3) the degree of a secondary immune response is weak when re-exposed to the same antigen. Therefore, from the viewpoint of designing an antigen that induces an immune response, in the case where the antigen injected into the body of a subject induces only a humoral immunity by IgM, it is highly likely that the desired effect will not be obtained. Therefore, it is very important to design an antigen so as to induce a humoral immunity by IgG.
The humoral immunity that produces IgG mainly occurs in the germinal center of the spleen or lymph node, and it proceeds by the complex action of B cells, helper T cells, and antigen-presenting cells (APCs). The overall process is as follows. 1) B cells recognize invading antigens (mainly proteins or peptide antigens). 2) After the antigen-presenting cells endocytose the antigens (or fragments thereof) and cut them into smaller fragments within the cells, and present some of the fragments to MHC Class II on the surface of the antigen-presenting cells. 3) Helper T cells recognize the antigen fragments presented to the MHC Class II. 4) The helper T cells transmit a differentiation signal to the B cells (antigen-recognized cells). 5) The B cells are activated and some differentiate into plasma cells to produce an IgG antibody having a high specific binding ability to the antigens. 6) As a result of the activation of the B cells, some cells differentiate into memory B cells and are stored in the body so that they can trigger an immune response that quickly produces an IgG antigen when the same antigens re-invade.
Antigen-presenting cells are a collective term for cells which are capable of endocytosing protein fragments or peptides, cleaving them into shorter peptide fragments, placing them on MHC Class II, and presenting them on the surface of the antigen-presenting cells. Major antigen-presenting cells include B cells, macrophages, dendritic cells, etc. Antigen-presenting cells transport the endocytosed antigen fragments from the site of infection to the lymph node, and present the antigen fragments to helper T cells by MHC Class II, and thereby play a role in inducing an immune response by activating helper T cells that recognize the same.
MHC Class II is a molecule expressed on the surface of antigen-presenting cells and has a heterodimer structure consisting of a/si chains. MHC Class II, due to its structure, can bind to a peptide of a certain length and present the same. Antigen-presenting cells allow peptide fragments derived from foreign antigens to bind to MHC Class II and present them on the cell surface. HLA gene complexes (human leukocyte antigen gene complexes) are involved in the expression of MHC Class II in humans, and among them, gene complexes such as HLA-DP, DQ, DR, etc. are known to be involved in the expression of MHC Class II cell surface receptors on the surface of antigen-presenting cells. In humans, the HLA-DR gene is known to have various alleles according to race, and about 12 types of HLA-DR genes are known as the most frequently found alleles.
Although there is a slight difference between the literatures, the length of the peptide presented in MHC Class II is known to be in the range of about a 17mer to about a 24mer. Therefore, antigen-presenting cells do not present the endocytosed antigen proteins or peptide fragments on MHC Class II as they are, but they undergo a process of cleavage making them into smaller fragments of 17mers to 24mers. The antigen fragments (proteins or peptide fragments) endocytosed by the antigen-presenting cells are present in the endosome, and the endosome is fused with the lysosome of the antigen-presenting cells. Thereafter, the antigen fragments are cleaved into shorter peptides by various kinds of degrading enzymes present in the lysosome. Examples of the degrading enzymes include endopeptidases and exopeptidases. While endopeptidases act to cleave the antigen fragments by acting on the peptide bond inside the antigen fragments, exopeptidases mainly act to cleave the antigen fragments by acting on peptide bonds at both ends of the antigen fragments. When the antigen fragments are cleaved into peptides of an appropriate size through the above process, some of them are bound to MHC Class II present in the inner membrane of the lysosome. The lysosome returns to the cell surface and fuses with the cell's plasma membrane, and thereby MHC Class II and the peptide fragments bound thereto are exposed on the surface of antigen-presenting cells. This whole process is also called “the process by which antigen-presenting cells present antigens”.
Helper T lymphocytes are also known as CD4+ cells because they express CD4. Helper T cells express T cell receptors (TCRs) which have the ability to bind to MHC Class II on the surface. The T cell receptors generally form a complex with CD3. When antigens (e.g., peptide fragments) transported by antigen-presenting cells to lymph nodes are presented through MHC Class II, helper T cells recognize the antigen fragments presented above. The T cell receptor-CD3 complex and CD4 are involved in this recognition process. When the helper T cells successfully recognize the antigen fragments, they are activated to secrete various cytokines or differentiate themselves. The secreted cytokines are involved in the differentiation of B cells, which will be described later.
Under the influence of the cytokines (e.g., interleukin-4 (IL-4), etc.) secreted by helper T cells, there occurs an immunoglobulin class switching of the B cells, thereby changing the isotypes of the antibodies produced by the B cells (e.g., from IgM to IgG). In addition, some of the B cells are differentiated into memory B cells and stored so as to induce a rapid immune response when the same antigens invade again, and some are differentiated into plasma cells and actively produce IgG antibodies.
For the occurrence of a humoral immunity by IgG, it is essential that 1) a specific three-dimensional structure of an antigen be recognized by B cells, and 2) some fragments of the antigen be recognized by helper T cells through MHC Class II. In general, although the part of an antigen recognized by B cells and the part of an antigen recognized by helper T cells are different from each other, and they activate an immune response through pathways different from each other, it is generally known that the immune response occurs only when the part recognized by B cells (B-cell epitope) and the part recognized by helper T cells (h epitope) have at least a certain linkage. For example, the B-cell epitope and the Th epitope may be included in one molecule, form a conjugate, or have other linkages.
Things to Consider in Designing Peptides that can be Used as Immunotherapeutics
As described above, immunotherapeutics are required due to their characteristics that 1) they be able to stably induce an immune response in the body of a subject, 2) they be able to minimize side effects by uniformly inducing only the intended antibody in the body of a subject; and 3) for their commercialization, they be easily synthesized and their production cost be reasonable. Therefore, in designing a peptide that can be used as an immunotherapeutic, the following three conditions should be essentially considered: 1) the peptide should exhibit a certain level of immunogenicity, 2) the peptide should trigger an immune response in the body of a subject that uniformly induces antigen recognition specificity of the antibody intended in advance, the isotype that controls physiological functions of the antibody, etc., and 3) the peptide should be easy to synthesize in consideration of economic feasibility.
As disclosed in previously filed patent application U.S. Ser. No. 10/378,707 and PCT/KR2005/000784, and Kim et al. (2016. An apolipoprotein B100 mimotope prevents obesity in mice, Clinical Science 130, 105-116), it is known that antibodies specific to an artificially produced peptide with a specific sequence can also bind to an exposed site of the ApoB-100 protein in an LDL molecule, and thereby it can function as immunotherapeutics. Using such a characteristic, immunotherapeutics including the peptide were designed and are disclosed in the above patent applications, etc. However, the prior art was mainly focused on improving the immunogenicity of the peptide, for example, 1) preparing a long continuous identical sequence (concatemer) of the peptide, 2) designing an immunotherapeutic by linking a helper T cell epitope (that is sufficiently long at a protein level) to the concatemer, etc. Accordingly, conventionally designed immunotherapeutics had limitations in that 1) various types of antibodies were induced and the uniformity was decreased due to the presence of various epitopes (antigenic determinants), and 2) the economic feasibility was low due to their high production cost.
As for the peptides for use as immunotherapeutics, no principle has been established with regard to 1) uniform induction of only the intended immune response and 2) design of a peptide that is easy to synthesize and has a low production cost. Accordingly, in the present specification, technical matters to be considered in the design of peptides for use as immunotherapeutics and methods for designing the same will be provided.
The peptides provided herein include at least one peptide unit (a block of peptide). The peptide unit includes at least one B-cell epitope, at least one Th epitope, and an appropriate number of auxiliary parts. In an embodiment, the peptide may include one peptide unit. In another embodiment, the peptide may include two or more peptide units.
The peptide unit is a part designed 1) to exhibit immunogenicity beyond a certain level, and 2) to uniformly induce only the intended antibody in advance. Therefore, the peptide unit provided herein has properties suitable for use as an immunotherapeutic.
Since the peptide unit is designed with a relatively short length, it is easy to synthesize and the production cost is low. The peptide is designed using a peptide unit as a component thereof, and specifically, it is designed in a form in which one or more of the peptide units are linked. When the peptide includes only a small number of the peptide units, the overall peptide length is short, thus having the advantage of easy synthesis. Even when the peptide has a relatively long sequence including a plurality of peptide units, the peptide unit itself is well designed for easy synthesis, and thus, it is possible to prepare the peptide in such a manner by synthesizing the peptide units in parallel and then linking these peptide units. As a result, the peptide provided herein has a characteristic of being easy to synthesize, which is the characteristic suitable for the use of the peptide as an immunotherapeutic, in addition to the characteristics of the peptide unit described above.
When the peptide is injected into the body of a subject, it has a function of uniformly inducing only antibodies capable of specifically binding to the B-cell epitope included in the peptide.
The peptides provided herein include one or more B-cell epitopes. As used herein, the term B-cell epitope refers to a unit of peptide that is intentionally designed to induce a homogeneous antibody of one type. Therefore, when the peptide including the B-cell epitope is injected into the body of a subject, it results in that one type of antibody is dominantly induced per type of a B-cell epitope.
The B-cell epitope includes a part for forming a three-dimensional structure and an adjacent part thereof. The part for forming a three-dimensional structure is the part that forms a peptide with a higher order structure, and this part is designed so that B cells can recognize the peptide with a higher order structure and produce an antibody that can specifically bind to the same. The adjacent part is a part which directly or indirectly influences the part for forming a three-dimensional structure to stably form a higher order structure. Specifically, the adjacent part may have functions such as 1) a function of the part for forming a three-dimensional structure to form a specific structure, 2) a linker function that does not affect the part for forming a three-dimensional structure when the B-cell epitope is linked to another part within a peptide unit, 3) a function of protecting the part for forming a three-dimensional structure, etc., but their functions are not limited thereto. In an embodiment, the B-cell epitope may have a sequence in which a first part for forming a three-dimensional structure and a first adjacent part thereof is linked in order from the N-terminus to the C-terminus. In another embodiment, the B-cell epitope may have a sequence in which a second adjacent part, a second part for forming a three-dimensional structure, and a third adjacent part are sequentially linked in order from the N-terminus to the C-terminus. In still another embodiment, the B-cell epitope may have a sequence in which a third part for forming a three-dimensional structure and a fourth adjacent part are sequentially linked in order from the N-terminus to the C-terminus.
The B-cell epitope should be able to uniformly induce the production of antibodies capable of recognizing the three-dimensional structure of B cells and specifically binding thereto. The three-dimensional structure recognized by B cells can be expressed through an appropriate peptide with a higher order structure. Therefore, the B-cell epitope is designed to include a part for forming a three-dimensional structure that forms a peptide with a higher order structure. The part for forming a three-dimensional structure may form an intended peptide with a higher order structure depending on the purpose. In an embodiment, the part for forming a three-dimensional structure may include an α-helix structure. In another embodiment, the part for forming a three-dimensional structure may include a β structure. Instill another embodiment, the part for forming a three-dimensional structure may include α-helix and/or β structures. In another embodiment, the part for forming a three-dimensional structure may include a peptide with a tertiary structure. In still another embodiment, the part for forming a three-dimensional structure may include a peptide with a quaternary structure.
When designing the B-cell epitope, it is not essential that all sequences form a peptide with a higher order structure. In other words, the B-cell epitope may be designed to additionally include an adjacent part, in addition to the part for forming a three-dimensional structure. The adjacent part may affect the part for forming a three-dimensional structure so that it stably forms a higher order structure. The adjacent part may perform various other functions, and its role may overlap with that of an auxiliary part. In an embodiment, the adjacent part may have a linker function. In another embodiment, the adjacent part may have a protective function for the part for forming a three-dimensional structure. In still another embodiment, the adjacent part may have one or more functions.
The B-cell epitope should have 1) a size large enough to be recognized by B cells and 2) one type or a very few types of antibodies that specifically binds to the B-cell epitope. The length of the B-cell epitope should be limited to an appropriate level. When the length of the B-cell epitope is too short, it is not recognized by B cells and thus does not have an antibody inducing ability, whereas when the length of the B-cell epitope is too long, various types of antibodies may be induced, which deviates from the intended purpose. In an embodiment, the length of the B-cell epitope may be about 8mer, about 9mer, about 10 mer, about 11 mer, about 12mer, about 13mer, about 14mer, about 15mer, about 16mer, about 17mer, about 18mer, about 20mer, about 21mer, about 22mer, about 23mer, about 24mer, about 25mer, about 26mer, about 27mer, about 28mer, about 29mer, or about 30mer.
In another embodiment, the length of the B-cell epitope may have a value within the two numerical ranges selected in the immediately preceding sentence.
In an embodiment, the B-cell epitope may be one that induces an antibody targeting apolipoprotein B-100. In another embodiment, the B-cell epitope may be a fragment of apolipoprotein B-100, and/or a mimotope of apolipoprotein B-100. In still another embodiment, the B-cell epitope is characterized in that it induces an antibody that targets a site selected from the following: an externally exposed site of apolipoprotein B-100 included in low-density lipoprotein (LDL); and an externally exposed site of apolipoprotein B-100 included in very low-density lipoprotein (VLDL).
In an embodiment, the B-cell epitope is a peptide includes a sequence selected from a group consisting of RNVPPIFNDVYWIAF(SEQ ID NO: 6), CRFRGLISLSQVYLS(SEQ ID NO: 7), KTTKQSFDLSVKAQYKKNKH(SEQ ID NO: 8), RNVPPIFNDVY(SEQ ID NO: 9), CRFRGLISLSQ(SEQ ID NO: 10), KTTKQSFDLSVK(SEQ ID NO: 11), RNVPPIFNDVYW(SEQ ID NO: 12), CRFRGLISLSQV(SEQ ID NO: 13), KTTKQSFDLSVKAQYKK(SEQ ID NO: 14), RNVPPIFNDVYWI(SEQ ID NO: 15), CRFRGLISLSQVY(SEQ ID NO: 16), KTTKQSFDLSVKAQYKKN(SEQ ID NO: 17), PIFNDVYWIAF(SEQ ID NO: 18), GLISLSQVYLS(SEQ ID NO: 19), QSFDLSVKAQYKKNKH(SEQ ID NO: 20), PPIFNDVYWIAF(SEQ ID NO: 21), RGLISLSQVYLS(SEQ ID NO: 22), KQSFDLSVKAQYKKNKH(SEQ ID NO: 23), VPPIFNDVYWIAF(SEQ ID NO: 24), FRGLISLSQVYLS(SEQ ID NO: 25), TKQSFDLSVKAQYKKNKH(SEQ ID NO: 26), NVPPIFNDVYWIA(SEQ ID NO: 27), RFRGLISLSQVYL(SEQ ID NO: 28), TKQSFDLSVKAQYKKN(SEQ ID NO: 29), VPPIFNDVYWI(SEQ ID NO: 30), FRGLISLSQVY(SEQ ID NO: 31), TKQSFDLSVKAQYKKN(SEQ ID NO: 32), PPIFNDVYW(SEQ ID NO: 33), RGLISLSQV(SEQ ID NO: 34), KQSFDLSVKAQYKK(SEQ ID NO: 35), RFRGLISLSQVYLDP(SEQ ID NO: 221), SVCGCPVGHHDVVGL(SEQ ID NO: 222).
In another embodiment, the B-cell epitope may be a peptide which includes an epitope that is included in a peptide selected from the group consisting of SEQ ID NOS: 6 to 35 and 221 to 222.
In the present specification, sequences similar to the exemplary sequences of the B-cell epitope are disclosed. In an embodiment, the B-cell epitope may have a sequence having an identity of 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100%, to those sequences selected from the group consisting of SEQ ID NOS: 6 to 34 and SEQ ID NO: 221 to 222. In another embodiment, the B-cell epitope may be a sequence that matches the selected sequence by more than a value selected in the immediately preceding sentence. For example, the B-cell epitope may have a sequence that is 90% or more identical to SEQ ID NO: 6.
The Th epitope included in the peptide provided herein refers to a part which is designed such that after the peptide is endocytosed by antigen-presenting cells, it binds to MHC Class II, is presented on the surface of the antigen-presenting cell, and functions to be recognized by helper T cells (Th, helper-T-lymphocytes), in the process of being presented on the surface of the antigen-presenting cells by MHC Class II. The process of presenting antigens in which antigen-presenting cells process the endocytosed peptide and allow it to bind to MHC Class II was described previously. In other words, the Th epitope is a part that plays a role to be recognized by helper T cells when the peptide is injected into the body of a subject; therefore, it plays a direct role in inducing an IgG-type antibody against the peptide.
The Th epitope is designed to have an anchor residue capable of binding to MHC Class II in its sequence. Whether an anchor residue is included in the sequence is an important factor that affects the function of the Th epitope. In an embodiment, the Th epitope may include as anchor residues one or more amino acids selected from the group consisting of tyrosine (Y), phenylalanine (F), tryptophan (W), arginine (R), leucine (L), valine (V), isoleucine (I), and methionine (M).
As the Th epitope, a Th epitope having an ability to bind to MHC Class II of a certain species may be selected according to its purpose. In an embodiment, the Th epitope may be a Th epitope having the ability to bind to human MHC Class II. In another embodiment, the Th epitope may be a Th epitope having the ability to bind to MHC Class II of a species belonging to a mammal. Specifically, the Th epitope may be a Th epitope having the ability to bind to MHC Class II of a mouse.
Due to the diverse traits of HLA gene complex, the structure of MHC Class II may vary between races and individuals. Accordingly, it is possible to design a Th epitope having an ability to bind to HLA-DP, HLA-DQ, and/or HLA-DR, which are MHC Class II molecules of a specific genetic trait. In an embodiment, the Th epitope may be a peptide sequence, which has a high binding ability to MHC Class II expressed by one or more HLA-DR genes selected from 2w2b, 2w2a, 3, 4w4, 4w14, 5, 7, 52a, 52b, 52c, and 53, which are HLA-DR1 alleles.
In an embodiment, the Th epitope may be a peptide sequence, which has a high binding ability to MHC Class II expressed by one or more genes selected from HLA-DQ5, HLA-DR, HLA-DR1 to HLA-DR8, HLA-DR11, HLA-DR13, HLA-DR14, HLA-DRw52, HLA-DR2w15, HLA-DPw4, each subtype of HLA-DRB1 (e.g., 0301, 01, 03, 04, 07, 08, 09, 11, 12, 13, 15, and 0301), and HLA-DRB5.
In another embodiment, the Th epitope may be a sequence named HA307-312 disclosed in Cara C. Wilson et al. (2001, Identification and Antigenicity of Broadly Cross-Reactive and Conserved Human Immunodeficiency Virus Type 1-Derived Helper T-Lymphocyte Epitopes, Journal of Virology, 75(9) 4195-4207).
In still another embodiment, the Th epitope may be one of the HLA Class II restricted epitopes disclosed in Table 2 of Christopher P Desmond et al. (2008, A systematic review of T-cell epitopes in hepatitis B virus: identification, genotypic variation and relevance to antiviral therapeutics, Antiviral Therapy 13:161-175).
Irrespective of the traits of the HLA gene complex, Th epitopes having an ability to bind to various MHC Class II are known, and it is possible to design a Th epitope that can bind to various MHC Class II regardless of genetic traits. In an embodiment, the Th epitope may be a sequence named “pan DR-binding peptide” disclosed in the U.S. patent application Ser. No. 08/305,871.
The Th epitope is designed to be presented by MHC Class II of antigen-presenting cells and recognized by helper T cells. Therefore, the Th epitope generally has a very high binding capacity to MHC Class II, and thus, the probability that the Th epitope may act as a B-Cell epitope is very low. In other words, the Th epitope is designed such that it does not induce an antibody which specifically binds to the three-dimensional structure of the Th epitope itself.
The Th epitope should be designed to have an appropriate length so that it can bind to one unit of MHC Class II. It is generally known that one unit of Th epitope that can directly bind to MHC Class II is at a length of about a 30mer (Abbas, A. K., Lichtman, A. H. and Pillai, S. Cellular and molecular immunology (pp 124-126), 7th Ed. (2012) Philadelphia PA, Elsevier Saunder, etc.). In addition, 1) when the length of the Th epitope becomes too short, there is a risk for the Th epitope to lose the ability to bind to MHC Class II, whereas 2) when the length of the Th epitope is too long, there is a room for the Th epitope to act independently as a B-cell epitope, thus deviating from the intended purpose. Therefore, it is necessary to design a Th epitope with an appropriate length.
Range of Length of Th Epitope
In an embodiment, the length of Th epitope may be 7mer, 8mer, 9mer, 10mer, 11 mer, 12mer, 13mer, 14mer, 15mer, 16mer, 17mer, 18mer, 19mer, 20mer, 21mer, 22mer, 23mer, 24mer, 25mer, 26mer, 27mer, 28mer, 29mer, 30mer, 31mer, 32mer, or 33mer. In another embodiment, the length of Th epitope may have a value within the two numerical ranges selected in the immediately preceding sentence. For example, the length of Th epitope may be in the range of 8mer to 32mer. For another example, the length of Th epitope may be in the range of 11 mer to 13mer.
In an embodiment, the Th epitope may be a peptide named “pan DR-binding peptide” disclosed in U.S. Pat. No. 305,871. In another embodiment, the Th epitope may be one of the peptides disclosed in Tables VIII A and IX of U.S. Pat. No. 6,413,935 B1. In still another embodiment, the Th epitope may have a peptide sequence satisfying the following structural Formula I:
N-Lys-X1-X2-Ala-Ala-X3-Thr-X4-X5-Ala-Ala-C
in which the X1 may be tyrosine (Tyr), phenylalanine (Phe), or L-cyclohexylalanine, but the X1 is not limited thereto.
The X2 may be a hydrophobic amino acid, or may be leucine (Leu) or isoleucine (lie), but the X2 is not limited thereto.
The X3 may be an aromatic or cyclic amino acid, or may be phenylalanine (Phe), tyrosine (Tyr), or histidine (His), but the X3 is not limited thereto.
The X4 may be an aliphatic long chain amino acid, or may be isoleucine (Ile) or valine (Val), but the X4 is not limited thereto.
X5 may be a charged amino acid, or may be arginine (Arg), leucine (Leu), aspartic acid (Asp), glutamine (Gin), or glycine (Gly), but the X5 is not limited thereto.
In an embodiment, the Th epitope may have a peptide sequence satisfying the following structural Formula II:

In this case, “a” denotes D-form alanine, “Z” denotes 6-aninohexanoic acid, and “(Cha)” denotes L-cyclohexylalanine.
In the present specification, sequences similar to the exemplary sequences of the Th epitope are disclosed. In an embodiment, the Th epitope may have a sequence, which have an identity of 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100% to SEQ ID NO: 1 to SEQ ID NO: 5, SEQ ID NO: 162 to SEQ ID NO: 192, SEQ ID NO: 195 to SEQ ID NO: 196, and SEQ ID NO: 223 to SEQ ID NO: 247, a sequence satisfying the above [Formula I], or a sequence satisfying the above [Formula II]. In another embodiment, the Th epitope may have a sequence which matches, by the number selected in the immediately preceding sentence or more, to SEQ ID NO: 1 to SEQ ID NO: 5, SEQ ID NO: 162 to SEQ ID NO: 192, SEQ ID NO: 195 to SEQ ID NO: 196, and SEQ ID NO: 223 to SEQ ID NO: 247, a sequence satisfying the above [Formula I], or a sequence satisfying the above [Formula II]. For example, the Th epitope may have a sequence which has an identity of 90% or more to the sequence of SEQ ID NO: 1.
The peptides disclosed herein may include one or more auxiliary parts. The auxiliary part collectively refers to an additional part which can directly or indirectly affect the peptide to cause an intended immune response in the body of a subject. The auxiliary part may have one or more functions, and the constitution of the peptide sequence and/or the position of the sequence may appropriately be designed according to the purpose.
The auxiliary part may function as a linker linking a B-cell epitope and a Th epitope. The B-cell epitope and the Th epitope may be directly linked or they may be linked through an auxiliary part serving as a linker. In addition, the auxiliary part may be designed to have a linker function that links a plurality of units included in the peptide. In an embodiment, the sequence of the auxiliary part may be located between the sequence of the B-cell epitope and the sequence of the Th epitope. In particular, the auxiliary part has a linker function that links the B-cell epitope and the Th epitope. In another embodiment, the sequence of the auxiliary part may be located between the sequence of the first peptide unit and the sequence of the second peptide unit in the peptide. In particular, the auxiliary part has a linker function for linking the first peptide unit and the second peptide unit.
In the case of the peptide unit provided herein, it is characterized by having a relatively short sequence length. Accordingly, when a peptide including the peptide unit is injected into the body of a subject, the Th epitope sequence may be degraded before being recognized by helper T cells, and thus, the intended immune response may not occur. In an embodiment, the protective unit may protect the Th epitope from being cleaved by an enzyme in the body of the subject. For example, the enzyme in the body of the subject may be a peptidase. Specifically, the peptidase may be an exopeptidase and/or an endopeptidase, but the peptidase is not limited thereto. In another embodiment, the auxiliary part may be linked to the N-terminus and/or C-terminus of the Th epitope. In particular, the auxiliary part has a function of protecting the Th epitope. In still another embodiment, the auxiliary part may include at least one nonstandard amino acid.
The auxiliary part may be designed to be linked to both ends of the peptide unit to thereby have a function of allowing the peptide to form a cyclic form. In an embodiment, the peptide may include a first auxiliary part at the N-terminus and a second auxiliary part at the C-terminus. In particular, the first auxiliary part and the second auxiliary part may each include one or more cysteines (S). In another embodiment, the peptide may exist in a cyclic form. In particular, the N-terminus and C-terminus of the peptide may be linked through an auxiliary part.
The auxiliary part may have an additional function in addition to the above functions. In an embodiment, the auxiliary part may include a hydrophilic amino acid and may have a function of increasing the solubility of a peptide. In another embodiment, the auxiliary part may consist of a sequence that is biologically inactive in the body of a subject. In particular, the auxiliary part has no effect on the functions of the B-cell epitope and the Th epitope, and may have a dummy function to extend the length of the peptide. Specifically, the peptide may be a His-tag, but is not limited thereto.
The auxiliary part may have one or more functions. In an embodiment, the auxiliary part may have a linker function, a protective function, a cyclic form forming function, a dummy function, and/or a solubility increasing function.
The auxiliary part may include one or more nonstandard amino acids. The artificial amino acid may be necessary for an auxiliary part to exhibit the linker function, protective function, and/or other functions. In an embodiment, the auxiliary part may include at least one nonstandard amino acid. Specifically, the nonstandard amino acid may be one or more nonstandard amino acids selected from the group consisting of L-cyclohexylalanine, D-form alanine, and 6-aminohexanoic acid, but the nonstandard amino acid is not limited thereto.
The auxiliary part may be designed to have an appropriate length according to its function. When the auxiliary part has multiple functions, it may be designed to have an appropriate length to exhibit all of the multiple functions. In an embodiment, the length of the auxiliary part may be 1 mer, 2mer, 3mer, 4mer, 5mer, 6mer, 7mer, 8mer, 9mer, 10mer, 11 mer, 12mer, 13mer, 14mer, 15mer, 16mer, 17mer, 18mer, 19mer, 20mer, 21mer, 22mer, 23mer, 24mer, 25mer, 26mer, 27mer, 28mer, 29mer, 30mer, or 31mer or longer. In another embodiment, the length of the auxiliary part may have a value within the two numerical ranges of the immediately preceding sentence. For example, the length of the auxiliary part may be in the range of 1 mer to 8mer. For another example, the length of the auxiliary part may be in the range of 15mer to 26mer.
The auxiliary part does not significantly affect the function of the peptide unit and/or peptide disclosed herein to induce an antibody that specifically binds to the B-cell epitope in the body of a subject.
Embodiments of Sequences of Auxiliary Part

In particular, “a” denotes D-form alanine and “Z” denotes 6-aminohexanoic acid.
Designing Peptide Unit—Overall
A method for designing a possible peptide unit and a form thereof will be described hereinbelow. Each unit may include at least one B-cell epitope and at least one Th epitope, and may include an appropriate number of auxiliary parts. The linking order of the B-cell epitope, the Th epitope, and the auxiliary part is exemplified for each type. Unless otherwise specified, the design of each part included in the peptide unit basically follows the design principle described above.
As a peptide unit provided herein, a peptide unit, which can include 1) one B-cell epitope and one Th epitope and 2) one or more an auxiliary part, is named “unit-A”. The function of the auxiliary part is not particularly limited as long as it does not impair the functions of the B-cell epitope and the Th epitope, and is appropriately designed as necessary.
In an embodiment, the unit-A may be one in which the first B-cell epitope and the first Th epitope are sequentially linked in the direction from the N-terminus to the C-terminus.
Furthermore, the unit-A may further include a first auxiliary part. When the unit-A includes the first auxiliary part, the sequence of the first auxiliary part is located at the N-terminal side relative to the sequence of the first B-cell epitope within the unit-A sequence. In particular, the first auxiliary part may have a dummy function, a solubility improving function, a linker function, and/or a cyclic form-forming function, but the functions of the first auxiliary part are not limited thereto.
Furthermore, the unit-A may further include a second auxiliary part. When the unit-A includes the second auxiliary part, the sequence of the second auxiliary part is located between the sequence of the first B-cell epitope and the sequence of the first Th epitope within the unit-A sequence. In particular, the second auxiliary part may have a dummy function, a solubility improving function, a linker function, and/or a protective function, but the functions of the second auxiliary part are not limited thereto.
Furthermore, the unit-A may further include a third auxiliary part. When the unit-A includes the third auxiliary part, the sequence of the third auxiliary part is located at the C-terminal side relative to the sequence of the first Th epitope within the unit-A sequence. In particular, the third auxiliary part may have a dummy function, a solubility improving function, a linker function, a protective function and/or a cyclic form-forming function, but the functions of the third auxiliary part are not limited thereto.
In another embodiment, the unit-A may be one in which a second Th epitope and a second B-cell epitope are sequentially linked in the direction from the N-terminus to the C-terminus.
Furthermore, the unit-A may further include a fourth auxiliary part. When the unit-A includes the fourth auxiliary part, the sequence of the fourth auxiliary part is located at the N-terminal side relative to the sequence of the second Th epitope within the unit-A sequence. In particular, the fourth auxiliary part may have a dummy function, a solubility improving function, a linker function, and/or a cyclic form-forming function, but the functions of the fourth auxiliary part are not limited thereto.
Furthermore, the unit-A may further include a fifth auxiliary part. When the unit-A includes the fifth auxiliary part, the sequence of the fifth auxiliary part is located between the sequence of the second B-cell epitope and the sequence of the second Th epitope within the unit-A sequence. In particular, the fifth auxiliary part may have a dummy function, a solubility improving function, a linker function, and/or a cyclic form-forming function, but the functions of the fifth auxiliary part are not limited thereto.
Furthermore, the unit-A may further include a sixth auxiliary part. When the unit-A includes the sixth auxiliary part, the sequence of the sixth auxiliary part is located at the C-terminal side relative to the sequence of the second B-cell epitope within the unit-A sequence. In particular, the sixth auxiliary part may have a dummy function, a solubility improving function, a linker function, and/or a cyclic form-forming function, but the functions of the sixth auxiliary part are not limited thereto.
In an embodiment, the unit-A is a peptide represented by the following [Formula A] or [Formula A′].
N-A1-B1-A2-T1-A3-C [Formula A]
N-A4-T2-A5-B2-A6-C [Formula A]
The B1 and B2 are B-cell epitopes, and they follow the design principle described above.
The T1 and T2 are Th epitopes, and they follow the design principle described above.
The A1 to A6 are auxiliary parts and they may be omitted.
In particular, the A1 to A6 may have a dummy function, a solubility improving function, a linker function, and/or a cyclic form forming function, but the A1 to A6 are not limited thereto.
In an embodiment, the length of the unit-A may be about 16mer, about 17mer, about 18mer, about 19mer, about 20mer, about 21mer, about 22mer, about 23mer, about 24mer, about 25mer, about 26mer, about 27mer, about 28mer, about 29mer, about 30mer, about 31mer, about 32mer, about 33mer, about 34mer, about 35mer, about 36mer, about 37mer, about 38mer, about 39mer, about 40mer, about 41mer, about 42mer, about 43mer, about 44mer, about 45mer, about 46mer, about 47mer, about 48mer, about 49mer, about 50mer, about 51mer, about 52mer, about 53mer, about 54mer, about 55mer, about 56mer, about 57mer, about 58mer, about 59mer, about 60mer, about 61 mer, about 62mer, about 63mer, about 64mer, about 65mer, about 66mer, about 67mer, about 68mer, about 69mer, about 70mer, about 71 mer, about 72mer, about 73mer, about 74mer, about 75mer, about 76mer, about 77mer, about 78mer, about 79mer, about 80 mer, about 81mer, about 82mer, about 83mer, about 84mer, about 85mer, about 86mer, about 87mer, about 88mer, about 89mer, about 90mer, about 91mer, about 92mer, about 93mer, about 94mer, about 95mer, about 96mer, about 97mer, about 98mer, about 99mer, or about 100 mer. In another embodiment, the length of the unit-A may have a value within the two numerical ranges selected in the immediately preceding sentence. For example, the length of the unit-A may be in the range of about 16mer to about 30mer. For another example, the length of the unit-A may be in the range of about 23mer to about 60mer.
In an embodiment, the unit-A may have a sequence in which a first B-cell epitope, a first auxiliary part, and a first Th epitope are sequentially linked. In particular, the first auxiliary part has a linker function and it includes one or more artificial amino acids.
In another embodiment, the unit-A may have a sequence in which a second auxiliary part, a second B-cell epitope, a third auxiliary part, and a second Th epitope are sequentially linked. In particular, the second auxiliary part is His-tag, and the third auxiliary part has a linker function and it includes one or more artificial amino acids.
In still another embodiment, the unit-A may have a sequence in which a third B-cell epitope, a fourth auxiliary part, a third Th epitope, and a fifth auxiliary part are sequentially linked. In particular, the fourth auxiliary part has a linker function and a protective function, and the fifth auxiliary part has a protective function. The fourth auxiliary part and the fifth auxiliary part each include one or more artificial amino acids.
In still another embodiment, the unit-A may have a sequence in which a 6th an auxiliary part, a 4th B-cell epitope, a 7th auxiliary part, a 4th Th epitope, and an eighth auxiliary part are sequentially linked.

Nucleic Acid Encoding Peptide Unit and/or Peptide
Nucleic Acid Encoding Peptide Unit and/or Peptide—Overview
In the present specification, nucleic acids which encode peptide units and/or peptides disclosed above (hereinafter, “encoding nucleic acid”) are disclosed. While the peptide units and peptides disclosed herein may include nonstandard amino acids, there are no codons corresponding to the nonstandard amino acids in nature. Therefore, the nonstandard amino acids cannot be encoded by a general method. Accordingly, it is necessary to replace these nonstandard amino acids with appropriate standard amino acids to encode them in the form of nucleic acids. When the peptide unit and/or peptide do not include a nonstandard amino acid, the encoding nucleic acid can be designed using a nucleic acid codon corresponding to each standard amino acid.
For convenience of description, in the present specification, the peptide unit and/or peptide including the substitution of the nonstandard amino acid with an appropriate standard amino acid; and the peptide unit and/or peptide including only standard amino acids are referred to as a target peptide to be encoded, and the DNA and/or RNA encoding the target peptide to be encoded is referred to as an encoding nucleic acid. In particular, when the peptide unit and/or peptide do not include a nonstandard amino acid, the peptide unit and/or peptide has the same amino acid sequence as the target peptide to be encoded.
As used herein, the term “target peptide to be encoded” is a conceptual term introduced to easily describe the resultant encoding nucleic acid, and is independent of the method or procedure for preparing the encoding nucleic acid.
When a peptide unit and peptide disclosed herein include a nonstandard amino acid, the target peptide to be encoded is designed by replacing the same with an appropriate standard amino acid. When a peptide unit and peptide disclosed herein do not include a nonstandard amino acid, the corresponding target peptide to be encoded has the same sequence as the peptide unit and peptide. In an embodiment, the target peptide to be encoded may be one in which the nonstandard amino acid is replaced with any standard amino acid. In another embodiment, the target peptide to be encoded may be one in which the nonstandard amino acid is replaced with a standard amino acid that is identical to the same or has an equivalent function. In still another embodiment, the target peptide to be encoded may have a same sequence as the peptide unit and/or the peptide. In particular, the peptide unit and/or peptide are characterized by having no nonstandard amino acids,
The peptide unit and peptide disclosed herein include one or more Th epitopes. In particular, when the Th epitope is a sequence named PADRE disclosed in U.S. Pat. No. 305,871, it may include a nonstandard amino acid, L-cyclohexylalanine. According to the literature, the L-cyclohexylalanine may have both a function of protecting the PADRE from a peptide degrading enzyme and a function of an anchor residue capable of binding to MHC Class II. Therefore, the target peptide to be encoded is designed by replacing the L-cyclohexylalanine with an appropriate standard amino acid having the same or equivalent function. In an embodiment, the L-cyclohexylalanine may be substituted with any standard amino acid. In another embodiment, the L-cyclohexylalanine may be substituted with phenylalanine or tyrosine. In still another embodiment, the sequence of the target peptide to be encoded corresponding to the PADRE may be KFVAAWTLKAA (SEQ ID NO: 195), KYVAAWTLKAA (SEQ ID NO: 196), or KXVAAWTLKAA (SEQ ID NO: 197), in which the X refers to any standard amino acid.
In an embodiment, a sequence of the target peptide to be encoded is selected from RNVPPIFNDVYWIAFXXKXVAAWTLKAAXXCRFRGLISLSQVYLS(SEQ ID NO: 198), RNVPPIFNDVYWIAFXXKXVAAWTLKAAXXGSHHHHHHGSDDDDK(SEQ ID NO: 199), GSHHHHHHGSDDDDKXXKXVAAWTLKAAXXRNVPPIFNDVYWIAF(SEQ ID NO. 200), KTTKQSFDLSVKAQYKKNKHXXKXVAAWkTLKAAXXCRFRGLISLSQVYLS(SEQ ID NO: 201), RNVPPIFNDVYWIAFCRFRGLISLSQVYLSXXK(Cha)VAAWTLKAAXX(SEQ ID NO: 202), RNVPPIFNDVYWIAFXPKYVKQNTLKLATXCRFRGLISLSQVYLS(SEQ ID NO: 203), RNVPPIFNDVYWIAFXXKXVAAWTLKAAXX(SEQ ID NO: 204), RNVPPIFNDVYWIAFKXVAAWTLKAA(SEQ ID NO: 205), RNVPPIFNDVYWIAFKXVAAWTLKAAHHHHHH(SEQ ID NO: 206), RNVPPIFNDVYWIAFXXKXVAAWTLKAACRFRGLISLSQVYLS(SEQ ID NO: 207), RNVPPIFNDVYWIAFXXKXVAAWTLKAACR(SEQ ID NO: 208), RNVPPIFNDVYWIAFXXKFVAAWTLKAAXXCRFRGLISLSQVYLS(SEQ ID NO: 209), RNVPPIFNDVYWIAFXXKFVAAWTLKAAXX(SEQ ID NO: 210), RNVPPIFNDVYWIAFXXKFVAAWTLKAACRFRGLISLSQVYLS(SEQ ID NO: 211), and RNVPPIFNDVYWIAFXXKFVAAWTLKAACR(SEQ ID NO: 212). In this case, the “X” denotes any standard amino acid.
The encoding nucleic acid disclosed herein refers to a nucleic acid codon encoding the encoding target peptide. Since the sequences of the target peptides to be encoded are all standard amino acids, the encoding nucleic acid is designed based on the nucleic acid codon corresponding to each amino acid of the target peptide to be encoded. In particular, since one or more nucleic acid codons can correspond to one standard amino acid, two or more encoding nucleic acids encoding one target peptide to be encoded can eventually be designed. In an embodiment, the encoding nucleic acid may be a DNA and/or RNA codon encoding the target peptide to be encoded. In another embodiment, the encoding nucleic acid may have a DNA and/or RNA sequence, which is capable of a complementary binding to a DNA and/or RNA codon encoding the target peptide to be encoded.
The sequence of the encoding nucleic acid may be codon optimized, which is described in more detail below.
As described above, if the encoding nucleic acid is designed by simply linking the nucleic acid codon corresponding to each amino acid of the target peptide to be encoded, multiple encoding nucleic acids may be designed for one target nucleic acid to be encoded. Since 1 to 6 nucleic acid codons correspond per standard amino acid on average, the number of possible nucleic acid codon combinations increases exponentially as the amino acid sequence length increases. However, not all of these combinations are of equal importance. In general, there is a combination of nucleic acid codons capable of better expressing the target peptide to be encoded in cells, the combination may vary depending on the higher-order structure of the sequence itself, the type of the target cell into which the encoding nucleic acid is to be injected, etc. Discovering a combination of such a nucleic acid codon and specifying the discovered combination as a sequence of an encoding nucleic acid is called codon optimization. There is not necessarily only one codon-optimized sequence for one coding target peptide, and there may be two or more codon-optimized sequences.
In an embodiment, the encoding nucleic acid may have a codon optimized DNA and/or RNA sequence. In another embodiment, the encoding nucleic acid may have non-codon optimized DNA and/or RNA sequences.
Codon optimization of the encoding nucleic acid may be performed in consideration of a higher-order structure of the nucleic acid sequence itself. In an embodiment, the encoding nucleic acid may be codon-optimized in consideration of the GC contents of the sequence. In another embodiment, the sequence of the encoding nucleic acid may have a GC content in the range of about less than 1%, about 1%, about 2%, about 3%, about 4%, about 5%, about 6%, about 7%, about 8%, about 9%, about 10%, about 11%, about 12%, about 13%, about 14%, about 15%, about 16%, about 17%, about 18%, about 19%, about 20%, about 21%, about 22%, about 23%, about 24%, about 25%, about 26%, about 27%, about 28%, about 29%, about 30%, about 31%, about 32%, about 33%, about 34%, about 35%, about 36%, about 37%, about 38%, about 39%, about 40%, about 41%, about 42%, about 43%, about 44%, about 45%, about 46%, about 47%, about 48%, about 49%, about 50%, about 51%, about 52%, about 53%, about 54%, about 55%, about 56%, about 57%, about 58%, about 59%, about 60%, about 61%, about 62%, about 63%, about 64%, about 65%, about 66%, about 67%, about 68%, about 69%, about 70%, about 71%, about 72%, about 73%, about 74%, about 75%, about 76%, about 77%, about 78%, about 79%, about 80%, about 81%, about 82%, about 83%, about 84%, about 85%, about 86%, about 87%, about 88%, about 89%, about 90%, about 91%, about 92%, about 93%, about 94%, about 95%, about 96%, about 97%, about 98%, about 99%, or about 100%. In still another embodiment, the sequence of the encoding nucleic acid may have a GC content within the numerical range selected in the immediately preceding sentence. For example, the sequence of the encoding nucleic acid may have a GC content in the range of about 20% to about 50%. In still another embodiment, the sequence of the encoding nucleic acid may have a GC content less than the value selected in the immediately preceding sentence. For example, the sequence of the encoding nucleic acid may have a GC content of less than about 25%.
Codon optimization of the encoding nucleic acid may be achieved inconsideration of into which cell the encoding nucleic acid is to be injected and expressed. In an embodiment, the codon optimization of the encoding nucleic acid may be achieved in consideration of the codon usage in prokaryotic or eukaryotic cells. In another embodiment, the codon optimization of the encoding nucleic acid may be achieved in consideration of codon usage of animal cells. In still another embodiment, the codon optimization of the encoding nucleic acid may be achieved in consideration of mammalian codon usage. In still another embodiment, the codon optimization of the encoding nucleic acid may be achieved in consideration of human codon usage.

Hereinafter, the invention provided by the present specification will be described in more detail through Experimental Examples and Examples. These Examples are only for the purpose of illustrating the contents disclosed by the present specification, and it will be apparent to those skilled in the art that the scope of the contents disclosed by the present specification is not to be construed as being limited by these Examples.
This peptide was obtained by requesting a peptide synthesis company (Anygen, Korea, Gwangju City). The peptide of the present invention can be synthesized using conventionally known techniques (e.g., liquid peptide synthesis, solid phase peptide synthesis, convergent of small peptide fragments, etc.), and the synthesis method is not limited. For example, the OTP3 peptide of the present invention can be synthesized using the convergent method of small peptide fragments, in which sites of a long-chain peptide to which a coupling can easily be made are virtually cleaved and various parts are prepared based on this, and then combined with one another to thereby finally synthesize a desired peptide. The above convergent method has limitations in that specific amino acids must exist within the peptide sequence, and thus, the peptide may also be effectively synthesized by a combinatory peptide synthesis method, where the solution phase synthesis method and the solid phase peptide synthesis method are appropriately combined.
The purity of the peptide prepared in Experimental Example 1.1 was measured by performing HPLC analysis (Shimadzu HPLC LabSolutions) using a C-18 reversed-phase column (SHIMADZU C18 analytical column). As for the analysis conditions, the sample was separated and developed into an aqueous solution of 0.05% trifluoroacetate (TFA) and 0.05% TFA acetotrile solution at 60° C., and then the purity was confirmed by measuring the peak absorbance at a wavelength of 230 nm.
The molecular weight of the peptide prepared in Experimental Example 1.1 was analyzed with a mass spectrometer (AXIMA Assurance, MALDI-TOF, Shimadzu).
The peptide prepared in Experimental Example 1.1 was quantified by measuring the UV extinction coefficient (Ultrospec 3000 Pro UV/VIS spectrophotometer, Pharmacia). Specifically, the quantification was performed using the extinction coefficient at 280 nm.
A composition for in vivo administration was prepared by mixing the peptide prepared in Experimental Example 1.1, alhydrogel (Al(OH)3, manufactured by InvivoGe, Inc.), and PHAD (manufactured by Avanti). The specific process is as follows.
(1) The prepared peptide powder was dissolved in 100% dimethyl sulfoxide (DMSO) to obtain a concentration of 100 mg/L.
(2) PBS was added to the peptide-DMSO solution of(1) and mixed to prepare the peptide at a concentration of 50 mg/mL.
(3) PHAD was dissolved in 100% DMSO to a concentration of 10 mg/mL, and then diluted with distilled water to a concentration of 1 mg/mL.
(4) An alhydrogel adjuvant (Invivogen. USA) and the PHAD solution were added to the mixture of (2). The concentration of the mixed composition was 50 μg for the peptide, 10 μg for the PHAD, and 10% (v/v) for the Alhydrogel adjuvant, per 100 μL, which is the amount for one dose.
(5) After well mixing the mixture of (4), the resultant was reacted overnight while stirring with a rotator in a low temperature room (4° C.).
(6) For DSMO washing, the reactants of (5) were centrifuged at 1,400 rpm for 15 minutes, and the supernatant except for about 1 mL above the pellet was removed. Thereafter, 10 mL of PBS was added thereto and mixed.
(7) The washing process of (6) was repeated 3 times.
(8) After the final washing process, PBS was added thereto so as to adjust the final concentration of the composition. In particular, the peptide concentration was 50 μg/100 μL (in particular, 30 μg/100 μL in Example 4), the PHAD concentration was 10 μg/100 μL, and the hydrogel adjuvant concentration was 10% (v/v).
(9) The amount of peptide adsorbed to the aluminum gel was measured according to the method described in Experimental Example 1.3. As a result, it was confirmed that the adsorption rate was 95% or more and the peptide was used in the experiment.

According to Experimental Example 1.7, the composition for in vivo administration was administered to the test subject. In particular, the administration cycle was as follows: 8 weeks, 10 weeks, 12 weeks, and 14 weeks of age.
In order to confirm the experimental results of Experimental Example 7.1, the following experiments were performed in a test subject for each experimental group disclosed in [Table 12].
(1) According to Experimental Example 1.8, the weight of a test subject for each experimental group was measured.
(2) According to Experimental Example 1.9, the antibody titers observed in a test subject for each experimental group at 11 weeks, 16 weeks, and 19 weeks were confirmed. In particular, the target antigen was determined using RNVPPIFNDVYWIAF (SEQ ID NO: 6).
The experimental results are shown in
As a result of the experiment, all of the experimental groups 6-1 (P1) to experimental groups 6-9 (P9) showed a distinct weight loss effect compared to the control group (Obese), which were fed with a high-fat diet.
The results of the antibody titer test according to the experimental group can be interpreted as follows:
Since no antigen was administered to the control groups (i.e., Lean and Obese), antibody titers were not shown.
In consideration of the experimental design, in the experimental groups, the antibody titers to SEQ ID NO: 6 included in the peptides used were mainly confirmed. Although antibody titers to sequences other than SEQ ID NO: 6 included in the peptides used were not separately confirmed, the weight loss effect due to a humoral immunity by these was confirmed together.
Specific results will be described below.
In the case of Experimental Group 6-1 (P1), there were individuals showing a large antibody titer depending on the individual, and there were also individuals which showed no antibody titer. These results can be interpreted as follows: for some individuals of the experimental group 6-1 (P1), a humoral immunity to RNVPPIFNDVYWIAF (SEQ ID NO: 6) included in Example 6 was induced, thus showing both the weight loss effect and antibody titer observed; and although for some individuals, a humoral immunity to CRFRGLISLSQVYLS (SEQ ID NO: 7) included in Example 6 was induced, resulting in weight loss, the antigen used in the Enzyme-Linked Immunosorbent Assay (ELISA) consisted only of RNVPPIFNDVYWIAF (SEQ ID NO: 6) and there was no other antigen (i.e., the antigen of SEQ ID NO: 7), therefore, the antibody titer according to the above experiment was not observed even in the presence of the antibody.
In the case of experimental group 6-2 (P2), the antibody titer to RNVPPIFNDVYWIAF (SEQ ID NO: 6) included in Example 7 was observed, and the weight loss effect appeared, it can be interpreted that the B-cell epitope included in the peptide of Example 7 well induced a humoral immunity thereto.
In the case of experimental group 6-3 (P3), the antibody titer to RNVPPIFNDVYWIAF (SEQ ID NO: 6) included in Example 8 was observed, and the weight loss effect appeared, it can be interpreted that that the B-cell epitope included in the peptide of Example 8 well induced a humoral immunity thereto.
In the case of experimental group 6-4 (P4), it can be interpreted that a humoral immunity to KTTKQSFDLSVKAQYKKNKH (SEQ ID NO: 8) and/or CRFRGLISLSQVYLS (SEQ ID NO: 7) included in Example 9 was induced, thus antibody titers against RNVPPIFNDVYWIAF (SEQ ID NO: 6) were not shown, while there was a weight loss effect.
These results can be interpreted that for some individuals of the experimental group 6-5 (P5), a humoral immunity was induced against RNVPPIFNDVYWIAF (SEQ ID NO: 6) included in Example 10, such that both a weight loss effect and an antibody titer are observed, for the other individuals of the experimental group 6-5 (P5), a humoral immunity was induced against CRFRGLISLSQVYLS (SEQ ID NO: 7) included in Example 10, such that a weight loss effect is observed, but the antibody titer according to the above experiment was not observed.
In the case of experimental group 6-7 (P7), although there were some differences between individuals, antibodies to RNVPPIFNDVYWIAF (SEQ ID NO: 6) was observed and the weight loss effect appeared, therefore, it can be interpreted that the B-cell epitope included in the peptide of Example 11 well induced a humoral immunity.
In the case of experimental group 6-8 (P8), since the antibody titer against RNVPPIFNDVYWIAF (SEQ ID NO: 6) included in Example 12 was shown, and the weight loss effect was shown, it can be interpreted that the B-cell epitope included in the peptide of Example 12 well induced a humoral immunity.
In the case of experimental group 6-9 (P9), there were some differences between individuals. However, since the antibody against RNVPPIFNDVYWIAF (SEQ ID NO: 6) was observed and the weight loss effect appeared, it can be interpreted that the B-cell epitope included in the peptide of Example 13 well induced a humoral immunity.

An amino acid sequence of the peptide used in Experimental Example 11 (hereinafter referred to as “Example 11.1”) is as follows:
This peptide of Experimental Example 11.1 was obtained by requesting a peptide synthesis company (AmbioPharm, Inc.) to prepare the same. The results of peptide preparation are described below in [Table 16].
A composition for in vivo administration was prepared with the peptide prepared in Experimental Example 11.1 and referring to Experimental Example 1.5. The final concentration of the composition for in vivo administration was 50 μg/100 μl based on mass of Example 11.1. The specific composition ratio of the in vivo administration is identified in the following table:
Experimental animals are C57BL/6J male mice of 6 weeks of age (JAX Japan, Orient Bio). After bringing the mice in the cages, a normal diet (3.41 kcal/g, Regular chow, PicoLab Rodent Diet 20, #5053, LabDiet, USA) and water were sufficiently fed thereto: temperature and humidity were maintained at 22±2° C. 50±10%; 12-hour darkness (dark: PM 7:00 to AM 7:00) was automatically adjusted, which was applied to individual cages. After one-week application from the bring-in, a normal diet group was divided on the basis of body weight, and the diet for all the remaining subjects was replaced with a high-fat diet (60% kcal of fat, Research diet, D12492, USA), and DIO (Diet-induced obesity) induction started. An application to administer a hypodermic injection was performed in all the subjects one week prior to composition administration, and the subjects were divided into an intramuscular injection group and a hypodermic injection group based on body weight and body fat one day before the administration. Clinical signs (activity, mutation, bleeding, injury, malformation, skin, hair quality, ocular abnormality, etc.) were monitored once a day (upon monitoring at afternoon). Breeding and animal evaluation on all experimental animals were performed by the Experimental Animal Center in Lee Gil Ya Center and Diabetes Institute, Gacheon University, and they are bred in individual cages (IVC Rack System, 13×34×14 cm) in compliance with AAALAC (Association for Assessment and Accreditation of Laboratory Animal Care International) (Animal Experiment Approval No: LCDI-2021-0178).
The composition for in vivo administration prepared in Experimental Example 11.2 was administered to the experimental subjects prepared in Experimental Example 11.3. Specific experimental groups, including control groups, and administration conditions are described below in [Table 18].
Wegovy (2.4 mg/0.75 mL) was used as a positive control group (Con(+)).
The administration route and period are as follows:
With respect to the experimental group to which the peptide was administered under the conditions disclosed in Experimental Example 11.4, body weight and food intake were evaluated in the following manner:
With starting the administration, body weight (FX-2000i, A&D company, 0.01-2200 g) and food intake (CSG201F, OHAUS, 0.1 g-200 g) were measured twice a week. Weight gain (g) was calculated on the basis of a difference between the body weight at the starting date of the administration and the body weight at one day before six weeks passes after the administration, and weight gain rate (%, Change in BW from baseline) was calculated by comparing the weight gain rate according to the administration at one day before six weeks pass after the administration, with the negative control group (Con(−)). The food intake (g) was calculated by dividing a difference between the amount of food fed twice a week and the residual amount by the daily food intake by each subject, and caloric intake (kcal) was calculated by reflecting metabolizable energy values (kcal/gm) of normal diet and high-fat diet on the calculated daily food intake (g) (normal diet=3.02 kcal/gm, high-fat diet=5.24 kcal/gm). Average caloric intake (kcal/day) was calculated by an average value of daily caloric intake (kcal), and accumulated caloric intake (kcal) was calculated by adding accumulated daily caloric intake (kcal).
With respect to the experimental group to which the peptide was administered under the conditions disclosed in Experimental Example 11.4, whole body fat mass and lean body mass were measured in the following manner:
The whole body fat mass was measured by using Mini-spec(LF-90II, Bruker Optics GmbH) at 2:00 pm upon dividing the groups and six weeks after the administration. The Mini-spec equipment is an NMR analyzer measuring 1H, which measures the whole body fat mass and the lean body mass (LBM) without passing through 2D or 3D fast Fourier transformation (FFT), by using a difference of spin-spin relaxation time between water and fat from free induction decay (FID) data which is a time-domain signal, the whole body fat mass were measured without in-vivo anesthesia within five minutes.
To obtain an anti-obesity effect of peptide according to Experimental Example 11.5, the results in which change in body weight was measured are disclosed in
Upon setting up an experimental group of the mice used for evaluation, the body weight (g) of the normal control group (Normal) started at average 26.7±0.29 and that of the DIO inducing group started at 35.0±0.35.
With respect to the body weight (g) six weeks after the administration, the body weight of the normal control group was 28.9±0.39, that of the negative control group (Con(−)) was 45.1±1.20; the body weight of the negative control group was increased. The body weights of Case 1, Case 2, Case 3, and the positive control group (Con(+)) were 41.7±1.33, 38.6±1.31, 34.3±066, and 36.2±1.70, respectively, showing a significant reduction in body weight compared to the negative control group.
With respect to the weight gain (g) compared to initial weight six weeks after the administration, the weight gain (g) of the normal control group was 2.2±0.19, the negative control group was 10.2±0.55, Case 1 was 6.6±0.70, Case 2 was 3.4±0.72, Case 3 was −0.65±0.52, and the positive control group was 1.1±1.24, Case 2 and Case 3 showed a statistically significant reduction in body weight compared to the negative control group and Case 1, and showed no statistical difference from the positive control group. Even compared to Case 2, Case 3 showed a statistically significant reduction in body weight.
With respect to the weight gain rate (%) compared to initial weight six weeks after the administration and compared to the negative control group, the weight gain rate (%) of the normal control group was 21.1±0.70, that of Case 1 was 10.5±1.87, that of Case 2 was 19.8±1.92, that of Case 3 was 31.0±1.46, and that of the positive control group was 26.4±3.35. Like the weight gain (g), Case 2 and Case 3 showed a statistically significant reduction in body weight compared to the negative control group, and showed no statistical difference from the positive control group.
Case 3 to which the composition was administered once a week showed a statistically significant reduction in body weight compared to Case 2 to which the composition was administered once two weeks.
Comparing the weight reduction patterns between Case 3 and the positive control group, the positive control group showed a pattern that reduction and increase in body weight were repeated within one week, whereas Case 3 showed a pattern that the body weight was continually reduced.
To obtain an anti-obesity effect of peptide according to Experimental Example 11.6, the results in which changes in the whole body fat mass and the lean body mass were measured are disclosed in
Upon setting up an experimental group of the mice used for evaluation, the whole body fat mass of the normal control group started at 3.6±0.09 and that of the DIO mice group started at average 11.8±0.26.
With respect to the whole body fat mass (g) on six weeks after the administration, the whole body fat mass (g) of the normal control group was 4.4±0.18, that of the negative control group was 18.0±0.82, that of Case 1 was 15.0±1.03, that of Case 2 was 12.3±1.00, that of Case 3 was 8.5±0.54, and that of the positive control group was 10.1±1.52. In this regard, Case 2 and Case 3 showed a statistically significant reduction in body fat mass compared to the negative control group and Case 1, and showed no statistical difference from the positive control group. Case 3 and Case 2 showed no statistical difference between them.
With respect to the lean body mass (g) measured simultaneously with the whole body fat mass, Case 2 and Case 3 had no statistical difference from the positive control group, the negative control group, and Case 1 six weeks after the administration. However, the positive control group showed a statistically significant reduction in the lean body mass compared to all the groups including the normal control group. Case 2 and Case 3 showed no a statistical difference between them.
In terms of the amount of fat tissue (mg, epididymis fat and retroperitoneal fat) extracted from the mice fasting for 16 hours on 7 weeks after the administration, Case 2 showed no statistical difference from the negative control group and Case 1. However, Case 3 showed a significant reduction in epididymis fat tissue compared to the negative control group and Case 1, and showed no statistical difference from the positive control group. Case 2 and Case 3 had no statistical difference between them.
Among anti-obesity effectiveness indicators, weight gain (g) compared to initial weight, weight gain rate (%) compared to body weight/negative control group, and food intake were significantly reduced in Case 2 (Q2W) and Case 3 (Q1W) compared to the negative control group. Without change in lean body mass, the body fat was also reduced compared to the negative control group. In particular, Case 3 (Q1W) showed weight gain (g) compared to initial weight, weight gain rate (%) compared to body weight/negative control group, and body fat, similar to those of the positive control group (Q1W), and the positive control group (Q1W) showed a significant reduction in lean body mass but Case 3 (Q1W) showed no reduction in lean body mass.
As a result, the peptide (Case 2 or Case 3) of Example 11 was effective in reduction of body weight and body fat compared to the negative control group.
The peptide of Example 11.1 according to Experimental Example 11 was prepared and used for toxicity evaluation.
With the peptide according to Experimental Example 12.1, a composition for in-vivo administration was prepared referring to Experimental Example 1.4. The final concentration of the composition for in-vivo administration was 0.25 mg/0.5 mL, based on the mass of Example 11.1.
Animals to be used for the experiment are as follows.
With respect to the above-identified experiment animals, five animals at maximum by a group were received in a stainless steel cage (255W×465L×200H mm) hung for the application period, and 3 animals at maximum by each cage were used in the experiment.
The breeding environment of experimental animals is as follows:

Specific evaluation methods are as follows:
During the experiment, experiments about all the animals having disease or abnormal physical signs, etc., animals in critical condition, and dead animals were terminated at the researchers' discretion. After the expiry of the experiment period, all the animals were killed by euthanasia by use of CO2, and autopsy thereon was performed.
After the end of the experiment, the animals were evaluated through autopsy as follows:
1) It was inspected as to whether sacrificed animals show any abnormality on the external body, abdomen, thoracic cavity, and cranial cavity, and organs thereof were extracted for inspection.
2) Appropriate fixing solution was fixed by use of any organ showing abnormality with the naked eye, and was stained with hematoxylin and eosin, thereby taking a detailed biopsy.
3) With respect to the injection site, morphological degeneration, discoloration, and size of the injection site, etc. were inspected with the naked eye.
4) Injection sites were taken and stained with hematoxylin and eosin, and it was inspected by a microscope whether or not there is cellular infiltration, sphacelism, edema, etc.
Results of toxicity evaluation according to Experimental Examples 12.1 to 12.6 are as follows:
1) There were no animals dead, having signs of physical abnormalities, or in clinical conditions within the experiment period.
2) There were no animals showing abnormal signs within the experiment period.
3) As a result of autopsy after the end of the experiment, there were no noticeable abnormal signs in abdominal cavity, cranial cavity, and thoracic cavity, and there was also no abnormal legion.
4) The following signs were observed with respect to two subjects (Subject 1 and Subject 2):
Subject 1 (Male, G4): Minimal and dark red discoloration was partially generated on the right muscular injection site.
Subject 2 (Female. G2): Increase of minimum size was observed at right nodi lymphatic popliteales.
5) Weight measurement results of male and female subjects were indicated below in [Table 21] and [Table 22]:
As a result of toxicity evaluation, there was statistically insignificant local response in partial subjects, but it was determined that all of the peptide and the vaccine compositions comprising the peptide have no toxicity.
Taken together, the peptide of Example 11.1 did not show any particular toxicity in the rat single toxicity experiment.
A peptide unit, a peptide, and/or a nucleic acid encoding the same provided herein can be used to prepare an immunotherapeutic, particularly an agent for treating obesity, and the immunotherapeutic may show a therapeutic effect by generating an intended humoral immunity when administered into the body of a subject.
