BACKGROUND

Vaccination, a process in which antigenic materials are introduced in a host to elicit specific adaptive immunity, has proven to be an extremely efficacious prophylactic measure against various infectious diseases. While the vaccines currently approved by the FDA have remarkable public health value, significant improvements can still be made. For example, while the current quadrivalent inactivated influenza vaccines are efficient at inducing autologous neutralizing antibodies, they cannot efficiently induce humoral responses with broad coverage such that annual immunization with stocks that correspond the strains predicted to circulate is necessary. In the HIV space, induction of broadly neutralizing antibodies through active immunization has been identified as an extremely important approach to reduce global incidences of HIV-1 infections. While significant advances have been made in strategies that may result in elicitation of such antibodies in humans, with the use of either germline-targeting immunogens^1-4or stabilized native-like trimers^5-7relevant humoral responses are generated typically after multiple immunizations that can span over an entire year, and often result in induction of inconsistent responses across animals studied. Further, native-like trimers induce low and short-lived antibody titers in rhesus macaques, an important pre-clinical animal models for HIV vaccine development. An approach that results in more rapid induction of relevant humoral immunity is of critical need to translate promising vaccine candidates into the clinics. In the past-decade, advances in material engineering has created opportunities for the explorations of novel vaccine concepts such as nanoparticle vaccines^8,9. Nanoparticles, ranging from 20-200 nm in diameter, present antigens in a repetitive fashion and can robustly stimulate long-lasting humoral responses^10-12. However, large-scale translation of these nanoparticle vaccines into the clinical space remains challenging due to difficulties in the synthesis and purification of these nanoparticles¹³. Physical/electrostatic adsorption techniques used to conjugate nanomaterials to antigens may lack substrate specificities and gather contaminants; chemical conjugations involving functionalization of the protein amine/thiol groups can potentially alter the antigenic profiles; protein-capsid based virus-like particle (VLP) vaccines produced from cell lines are difficult to purify, frequently requiring both disassembly and reassembly to achieve proper folding^14,15Technologies that would allow de novo nanoparticle assemblies in the hosts can potentially surpass the synthesis and purification steps, facilitate rapid translation of promising vaccine candidates into the clinic and therefore be of major advantage. In addition, current protein nanoparticles cannot efficiently induce CD8+ T-cell responses¹⁶, severely limiting their utility in clearing viral pathogens that require Cytotoxic T Lymphocyte (CTL)− such as reduction of HIV-1 reservoir in humans. In this patent, we have demonstrated a novel way to produce in vivo potent nanoparticle vaccines using advanced synthetic nucleic acid electroporation technology that bypass the need for cumbersome in vitro assembly/purification steps. In addition, the nucleic-acid launched nanoparticles quickly induce robust and durable humoral responses, and significantly stronger CTL responses in comparison to protein/adjuvant-based nanoparticle vaccines. We have also demonstrated that the nucleic-acid launched nanoparticle platform does not depend on extensive opsonization by components of the innate immune system, unlike protein/adjuvant-based nanoparticles, showing that engineering/design of nanoparticle vaccines in the nucleic acid platform can be significantly simpler and faster.

SUMMARY OF EMBODIMENTS

There are significant limitations in administering therapeutically effective amounts of protein vaccines to subjects, including ensuring that appropriate levels of the vaccine become exposed to antigen presenting cells and ensuring that the magnitude of any immune response is sufficient after administration of a single bolus dose. Furthermore, protein vaccines are difficult to store for relatively long periods of time because of protein instability issues. DNA vaccination is an alternative vaccination technique but suffers from delivery difficulties. Encapsulation and delivery of DNA vaccines have been used in the context of gene therapy but are incredibly expensive processes that require extended periods of time for preparation and isolation of particles. Encapsulating the DNA vaccines with particle still has limitations with storage of the complex molecules.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate several embodiments of the disclosed method and compositions and together with the description, serve to explain the principles of the disclosed method and compositions.

FIGS. 1A, 1B, and 1C show the platform for optimization for DNA-launching of self-assembling nanoparticle vaccines. FIG. 1A depicts a study showing IgE leader sequences support trafficking of target protein into the secretory network. FIG. 1B depicts a strategy to enhance DNA cassettes encoding an IgE leader sequence with tRNA codon optimization, mRNA secondary structure optimization, and amino acid usage utilization. FIG. 1C depicts DNA cassettes that encode self assembling nanoparticles in vivo. IgE-GLT1 comprises an N-terminal IgE leader sequence to drive trafficking of antigens to cellular secretory pathway followed by eOD-GT8. IgE-GLT1-NP comprises an N-terminal IgE leader sequence, followed by C-term of Lumazine synthase enzyme to drive for spontaneous self-assembly of these nanoparticle vaccines, followed by eOD-GT8 at the C-terminus of this construct.

FIGS. 2A, 2B, 2C, 2D, and 2E shows that IgE-GLT1 and IgE-GLT1-NP are expressed in vitro. Transfected 293T cells were stained with VRC01 and Goat-anti-human 488 and DAPI. Optimization to incorporate N-terminal IgE-leader sequence significantly boosts in vitro expression. A) GLT1-NP w/o IgE-LS; B) GLT1 w/o IgE-LS; C) IgE-GLT1-NP; D) IgE-GLT1; E) pVAX.

FIGS. 3A, 3B, and 3C show that multimerized IgE-GLT1-NP can be detected from Expi293F transfection supernatant. A) Transfection Supernatant-SDS PAGE; B) Transfection supernatant-Native PAGE; C) Size Exclusion Chromatography. To screen for multimerization of IgE-GLT1-NP encoded by the DNA plasmid, transfection of Expi293F cells were carried out and cell culture supernatant was collected. Native gel electrophoresis was used to analyze multimerization pattern of IgE-GLT1-NP (with VRC01 as the primary antibody). IgE-GLT1-NP produce bands that migrate less than IgE-GLT1, giving evidence of in vitro multimerization of this construct. Size exclusion chromatography of transfections supernatant confirms that IgE-GLT1-NP was secreted in the 60mer form as predicted by the retention time (which allows for estimation of the molecular weight).

FIGS. 4A, 4B, 4C, and 4D show an example of in vivo expression of antigens by Confocal Microscopy. A) schematic diagram of injection schedule. Immunocompetent balb/c mice were injected with 100 ug of DNA-encoded IgE-GTL1-NP and sacrificed 7 d.p.i.; B) Naïve mice; C) IgE-GLT1; D) IgE-GLT1-NP. Using confocal microscopy, in vivo production of IgE-GLT1-NP in mice skeletal muscles is seen.

FIG. 5 shows a native PAGE Western providing first evidence of in vivo assembly/multimerization of nanoparticle vaccines. Using Native Page gel to analyze the muscle extracts of mice immunized with either IgE-GLT1-NP or IgE-GLT1, both immunogens can be detected in vivo. In addition, the IgE-GLT1-NP produce bands that migrate less than IgE-GLT1, giving first evidence of in vivo multimerization of IgE-GLT1-NP.

FIGS. 6A, 6B, and 6C depict microscopy images of vaccine encoded by transfected cells. FIG. 6A depicts low magnification of transmission electron microscopy (TEM) image of muscle section from mice immunized with IgE-GTL1-NP depicts. FIG. 6B depicts high magnification of IgE-GLT1-NP immunized muscle section showing formation of gold-labelled nanoparticles in the vesicles. FIG. 6C depicts high magnification of naïve mice muscle section demonstrating low background with the staining process.

FIGS. 7A, 7B depict extensive nanoparticle multimerization does not occur in the ER in vivo. FIGS. 7A and 7B depict TEM images of muscle sections from mice immunized with DNA-encoded IgE-GLT1-NP demonstrating the cellular endoplasmic reticulum is not the site for assembly of nanoparticles in vivo.

FIGS. 8A and 8B show well-formed DNA-launched nanoparticles observed in secretory vesicles in vivo. FIGS. 8A and 8B depict TEM images of muscle sections from mice immunized with DNA-encoded IgE-GLT1-NP, showing well-formed VRC01-gold labelled IgE-GLT1-NP nanoparticles in the cellular vesicles (11 and 17 visible copies of VRC01 binding are observed).

FIG. 9 shows DNA-launched nanoparticle traffics more efficiently to draining lymph nodes corresponding monomeric antigen. Nanoparticle antigen gets taken up into draining LN for presentation by FDCs more effectively than monomeric antigens.

FIGS. 10A, 10B, and 10C show IgE-GLT1-NP induces sero-conversion as designed DNA encoded molecule 1 week post injection. A) 7 d.p.i.; B) 14 d.p.i.; C) 21 d.p.i. Using ELISA, it was shown that mice injected with DNA-encoded IgE-GLT1-NP seroconverted 1 week post single injection. In contrast, IgE-GLT1 vaccinated mice do not have appreciable titers until 3 weeks post injection.

FIGS. 11A and 11B show IgE-GLT1-NP induces more potent humoral responses than IgE-GLT1mer. Strong and durable humoral responses are seen even with a single injection. 1 shot or 2 shots of DNA-encoded IgE-GLT1-NP resulted in higher antibody titers than DNA-encoded IgE-GLT1 for 19 weeks post injection (1-2 log difference).

FIGS. 12A, 12B, and 12C show SynDNA-launched IgE-GLT1-NP induces stronger responses in mouse strains with different haplotypes. A) schematic diagram of injection schedule; B) Balb/c responses; C) C57BL/6 responses. The same pattern holds across mice with different haplotypes (balb/C and C57BL/6). No seroconversion was seen in C57BL/6 mice with 2 shots of DNA-encoded IgE-GLT1 whereas high titers were observed for IgE-GLT1-NP.

FIGS. 13A, 13B, and 13C show extremely low dose of synDNA-encoded IgE-GLT1-NP induces robust humoral responses. A dose-dependent increase in humoral response to GT8 was observed only for IgE-GLT1. A) schematic diagram of injection schedule; B) Endpoint titers with monomers; C) Endpoint titers with nanoparticles.

FIGS. 14A and 14B show a competition binding ELISA assay and demonstrates that sera from mice immunized twice with DNA-encoded IgE-GLT1-NP can potently outcompete potent binding of VRC01 to monomeric IgE-GLT1, demonstrating proper in vivo folding of nanoparticles to expose the CD4 binding site on the immunogen for recognition. Both panels demonstrate that DNA-encoded IgE-GLT1-NP induces stronger epitope-specific responses than DNA-encoded IgE-GLT1.DNA-encoded IgE-GLT1-NP immunization was found to be able to induce functional responses in balb/C mice. Sera from mice immunized with 100 ug of either DNA-encoded IgE-GLT1 or DNA-encoded IgE-GLT1-NP 4 weeks post 2nd dose was used in a competition ELISA assay. Mice antibodies produced in IgE-GLT1-NP mice were found to be able to outcompete VRC01 binding to GT8 more efficiently than IgE-GLT1 immunized mice by 3 fold.

FIGS. 15A and 15B show improving cellular immunity is a unique challenge. Prior Nanoparticles have had little impact on cellular immunity. The engineered IgE-GTL1-NP induces more robust cellular responses than IgE-GLT1. A) schematic diagram of injection schedule; B) Elispot assay. IgE-GLT1-NP was found to induce stronger cellular responses than IgE-GLT1 as determined by IFN-g ELIspot assays. 25 ug of DNA-encoded IgE-GLT1-NP can induce 500× stronger IFNg responses than 25 ug of DNA-encoded IgE-GLT1

FIG. 16 shows DNA-launched nanoparticles induce more potent CD4-memory responses than corresponding monomers. Using Flow-base intracellular cytokine staining assay to look at memory CD4-T-cells responses (CD3+ C4+ CD44+ CD62L− subsets), IgE-GLT1-NP immunized mice were found to have stronger CD4 responses than IgE-GLT1 immunized mice. Remarkably, the LS domain provides more robust CD4-T-cell help than the GT8 domain.

FIG. 17 shows BALB/c CD8 memory T-cell responses to GT8 domain. DNA-encoded IgE-GLT1-NP can induce stronger CD8-T-cell responses to the antigenic domain in balb/c mice when we examine cytokine activation (IL-2, TNFa and IFNg) and degranulation marker CD107a than DNA-encoded IgE-GLT1. The cells are CD8+ CD44+ CD62L−.

FIG. 18 shows designed DNA launched nanoparticle assembly enhances CD8 response in BALB/c mice. DNA-launched nanoparticles induce 10× stronger CD8 responses than corresponding monomer.

FIG. 19 shows DNA-launched nanoparticles increase formation of CD8 memory T-cells.

FIG. 20 is a schematic diagram of the MBL complement pathway for enhanced antigen opsonization and uptake.

FIGS. 21A, and 21B show even DNA-launched nanoparticle can activate MBL in vivo, immunogenicity of DNA-based nanoparticles is independent of MBL, unlike proteins. A) Immunogenicity of protein nanoparticles is dependent on lectin-complement pathway. As responses induced in MBL and complement receptor knockouts mice are significantly lower than the wildtype controls. B) DNA-launched nanoparticles, however, can still robustly induce responses in these transgenic animals, showing an Independence of the lectin-complement pathway (even though DNA-launched nanoparticles are fully capable of binding to MBL as shown previously).

FIGS. 22A and 22B show In vitro produced IgE-GLT1-NP binds to Mannose-Binding Lectin with higher affinity than IgE-GLT1. A) VRC01 binding of in vitro purified antigens; B) MBL binding of in vitro purified antigens. Previous studies determined that activation of MBL-complement pathway is important for immunogenicity of protein-based eOD-GT8-60mer. Consistent with their reports, IgE-GLT1-NP expressed from the currently disclosed DNA-cassette can bind to MBL more strongly than monomeric IgE-GLT1. As a control, protein-based IgE-GLT1-NP and IgE-GLT1 bind to VRC01 equally strongly.

FIGS. 23A and 23B show DNA-launched in vivo expressed IgE-GLT1-NP also binds to MBL more strongly than IgE-GLT1. A) VRC01 binding of in vitro purified antigens; B) MBL binding of in vitro purified antigens. Similarly, the in vivo produced IgE-GLT1-NP in the muscle extract (7 d.p.i) was found to bind to MBL more strongly than in vivo produced IgE-GLT1.

DETAILED DESCRIPTION

The disclosed method and compositions may be understood more readily by reference to the following detailed description of particular embodiments and the Example included therein and to the FIGS. and their previous and following description.

It is to be understood that the disclosed method and compositions are not limited to specific synthetic methods, specific analytical techniques, or to particular reagents unless otherwise specified, and, as such, may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting.

It is understood that the disclosed method and compositions are not limited to the particular methodology, protocols, and reagents described as these may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present disclosure which will be limited only by the appended claims.

It must be noted that as used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural reference unless the context clearly dictates otherwise. Thus, for example, reference to “a nucleic acid sequence” includes a plurality of such sequences, reference to “the nucleic acid sequence” is a reference to one or more nucleic acid sequences and equivalents thereof known to those skilled in the art, and so forth.

As used herein, the terms “activate,” “stimulate,” “enhance” “increase” and/or “induce” (and like terms) are used interchangeably to generally refer to the act of improving or increasing, either directly or indirectly, a concentration, level, function, activity, or behavior relative to the natural, expected, or average, or relative to a control condition. “Activate” in context of an immunotherapy refers to a primary response induced by ligation of a cell surface moiety. For example, in the context of receptors, such stimulation entails the ligation of a receptor and a subsequent signal transduction event. Further, the stimulation event may activate a cell and upregulate or downregulate expression or secretion of a molecule. Thus, indirect or direct ligation of cell surface moieties, even in the absence of a direct signal transduction event, may result in the reorganization of cytoskeletal structures, or in the coalescing of cell surface moieties, each of which could serve to enhance, modify, or alter subsequent cellular responses. As used herein, the terms “activating CD8+ T cells” or “CD8+ T cell activation” refer to a process (e.g., a signaling event) causing or resulting in one or more cellular responses of a CD8+ T cell (CTL), selected from: proliferation, differentiation, cytokine secretion, cytotoxic effector molecule release, cytotoxic activity, and expression of activation markers. As used herein, an “activated CD8+ T cell” refers to a CD8+ T cell that has received an activating signal, and thus demonstrates one or more cellular responses, selected from proliferation, differentiation, cytokine secretion, cytotoxic effector molecule release, cytotoxic activity, and expression of activation markers. Suitable assays to measure CD8+ T cell activation are known in the art and are described herein.

The term “combination therapy” as used herein is meant to refer to administration of one or more therapeutic agents in a sequential manner, that is, wherein each therapeutic agent is administered at a different time, as well as administration of these therapeutic agents, or at least two of the therapeutic agents, in a substantially simultaneous manner. Substantially simultaneous administration can be accomplished, for example, by administering to the subject a single dose having a fixed ratio of each therapeutic agent or in multiple, individual doses for each of the therapeutic agents. For example, one combination of the present disclosure may comprise a pooled sample of one or more nucleic acid molecules comprising one or a plurality of expressible nucleic acid sequences and an adjuvant and/or an anti-viral agent administered at the same or different times. In some embodiments, the pharmaceutical composition of the disclosure can be formulated as a single, co-formulated pharmaceutical composition comprising one or more nucleic acid molecules comprising one or a plurality of expressible nucleic acid sequences and one or more adjuvants and/or one or more anti-viral agents. As another example, a combination of the present disclosure (e.g., DNA vaccines and anti-viral agent) may be formulated as separate pharmaceutical compositions that can be administered at the same or different time. As used herein, the term “simultaneously” is meant to refer to administration of one or more agents at the same time. For example, in certain embodiments, antiviral vaccine or immunogenic composition and antiviral agents are administered simultaneously). Simultaneously includes administration contemporaneously, that is during the same period of time. In certain embodiments, the one or more agents are administered simultaneously in the same hour, or simultaneously in the same day. Sequential or substantially simultaneous administration of each therapeutic agent can be effected by any appropriate route including, but not limited to, oral routes, intravenous routes, sub-cutaneous routes, intramuscular routes, direct absorption through mucous membrane tissues (e.g., nasal, mouth, vaginal, and rectal), and ocular routes (e.g., intravitreal, intraocular, etc.). The therapeutic agents can be administered by the same route or by different routes. For example, one component of a particular combination may be administered by intravenous injection while the other component(s) of the combination may be administered intramuscularly only. The components may be administered in any therapeutically effective sequence. A “combination” embraces groups of compounds or non-small chemical compound therapies useful as part of a combination therapy. In some embodiments, the therapeutic agent is an anti-retroviral therapy, (such as one or a combination of efavirenz, lamivudine and tenofovir disoproxil fumarate) or anti-flu therapy (such as TAMIFLU®). In some embodiments, the therapeutic agent is one or a combination of: abacavir/dolutegravir/lamivudine (Triumeq) dolutegravir/rilpivirine (Juluca), elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (Stribild), elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (Genvoya), efavirenz/emtricitabine/tenofovir disoproxil fumarate (Atripla), emtricitabine/rilpivirine/tenofovir disoproxil fumarate (Complera), emtricitabine/rilpivirine/tenofovir alafenamide (Odefsey), bictegravir, emtricitabine, and tenofovir alafenamide (Biktarvy). In some embodiments, the therapeutic agent is one or a combination of a reverse transcrioptase inhibitor of a retrovirus such as: efavirenz (Sustiva), etravirine (Intelence), nevirapine (Viramune), nevirapine extended-release (Viramune XR), rilpivirine (Edurant), delavirdine mesylate (Rescriptor). In some embodiments, the therapeutic agent is one or a combination of a protease inhibitor of a retrovirus, such as: atazanavir/cobicistat (Evotaz), darunavir/cobicistat (Prezcobix), lopinavir/ritonavir (Kaletra), ritonavir (Norvir), atazanavir (Reyataz), darunavir (Prezista), fosamprenavir (Lexiva), tipranavir (Aptivus).

As used herein, “expression” refers to the process by which a polynucleotide is transcribed from a DNA template (such as into and mRNA or other RNA transcript) and/or the process by which a transcribed mRNA (or administered mRNA) is translated into peptides, polypeptides, or proteins. Transcripts and encoded polypeptides may be collectively referred to as “gene product.” If the polynucleotide is derived from genomic DNA, expression may include splicing of the mRNA in a eukaryotic cell.

The terms “functional fragment” means any portion of a polypeptide or nucleic acid sequence from which the respective full-length polypeptide or nucleic acid relates that is of a sufficient length and has a sufficient structure to confer a biological affect that is at least similar or substantially similar to the full-length polypeptide or nucleic acid upon which the fragment is based. In some embodiments, a functional fragment is a portion of a full-length or wild-type nucleic acid sequence that encodes any one of the nucleic acid sequences disclosed herein, and said portion encodes a polypeptide of a certain length and/or structure that is less than full-length but encodes a domain that still biologically functional as compared to the full-length or wild-type protein. In some embodiments, the functional fragment may have a reduced biological activity, about equivalent biological activity, or an enhanced biological activity as compared to the wild-type or full-length polypeptide sequence upon which the fragment is based. In some embodiments, the functional fragment is derived from the sequence of an organism, such as a human. In such embodiments, the functional fragment may retain 99%, 98%, 97%, 96%, 95%, 94%, 93%, 92%, 91%, or 90% sequence identity to the wild-type human sequence upon which the sequence is derived. In some embodiments, the functional fragment may retain 85%, 80%, 75%, 70%, 65%, or 60% sequence identity to the wild-type sequence upon which the sequence is derived.

By “fragment” is meant a portion of a polypeptide or nucleic acid molecule. This portion contains, preferably, at least about about 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, or about 90% of the entire length of the reference nucleic acid molecule or polypeptide. A fragment may contain about 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 or more nucleotides or amino acids.

“Optional” or “optionally” means that the subsequently described event, circumstance, or material may or may not occur or be present, and that the description includes instances where the event, circumstance, or material occurs or is present and instances where it does not occur or is not present.

The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified unless clearly indicated to the contrary. Thus, as a non-limiting example, a reference to “A and/or B,” when used in conjunction with open-ended language such as “comprising” can refer, In some embodiments, to A without B (optionally including elements other than B); in another embodiment, to B without A (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.

As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, “either,” “one of,” “only one of,” or “exactly one of” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.

As used herein an “antigen” is meant to refer to any substance that elicits an immune response.

As used herein, the term “electroporation,” “electro-permeabilization,” or “electro-kinetic enhancement” (“EP”), are used interchangeably and are meant to refer to the use of a transmembrane electric field pulse to induce microscopic pathways (pores) in a bio-membrane; their presence allows biomolecules such as plasmids, oligonucleotides, siRNA, drugs, ions, and/or water to pass from one side of the cellular membrane to the other. In some of the disclosed methods of treatment or prevention, the method comprises a step of elecoporation of a subject's tissue for a sufficient time and with a sufficient electrical field capable of inducing uptake of the pharmaceutical compositions disclosed herein into the antigen-presenting cells. In some embodiments, the cells are antigen presenting cells.

The term “pharmaceutically acceptable excipient, carrier or diluent” as used herein is meant to refer to an excipient, carrier or diluent that can be administered to a subject, together with an agent, and which does not destroy the pharmacological activity thereof and is nontoxic when administered in doses sufficient to deliver a therapeutic amount of the agent. The term “pharmaceutically acceptable salt” of nucleic acids as used herein may be an acid or base salt that is generally considered in the art to be suitable for use in contact with the tissues of human beings or animals without excessive toxicity, irritation, allergic response, or other problem or complication. Such salts include mineral and organic acid salts of basic residues such as amines, as well as alkali or organic salts of acidic residues such as carboxylic acids. Specific pharmaceutical salts include, but are not limited to, salts of acids such as hydrochloric, phosphoric, hydrobromic, malic, glycolic, fumaric, sulfuric, sulfamic, suifanilic, formic, toluenesulfonie, methanesulfonic, benzene sulfonic, ethane disulfonic, 2-hydroxyethyl sulfonic, nitric, benzoic, 2-acetoxybenzoic, citric, tartaric, lactic, stearic, salicylic, glutamic, ascorbic, pamoic, succinic, fumaric, maleic, propionic, hydroxymaleic, hydroiodic, phenyiacetic, alkanoic such as acetic, HOOC—(CH2)n-COOH where n is 0-4, and the like. Similarly, pharmaceutically acceptable cations include, but are not limited to sodium, potassium, calcium, aluminum, lithium and ammonium. Those of ordinary skill in the art will recognize from this disclosure and the knowledge in the art that further pharmaceutically acceptable salts for the pooled viral specific antigens or polynucleotides provided herein, including those listed by Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., p. 1418 (1985). In general, a pharmaceutically acceptable acid or base salt can be synthesized from a parent compound that contains a basic or acidic moiety by any conventional chemical method. Briefly, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in an appropriate solvent.

As used herein, the terms “prevent,” “preventing,” “prevention,” “prophylactic treatment,” and the like, are meant to refer to reducing the probability of developing a disease or condition in a subject, who does not have, but is at risk of or susceptible to developing a disease or condition.

As used herein, the term “purified” means that the polynucleotide or polypeptide or fragment, variant, or derivative thereof is substantially free of other biological material with which it is naturally associated, or free from other biological materials derived, e.g., from a recombinant host cell that has been genetically engineered to express the polypeptide of the present disclosure. That is, e.g., a purified polypeptide of the present disclosure is a polypeptide that is at least from about 70 to 100% pure, i.e., the polypeptide is present in a composition wherein the polypeptide constitutes from about 70 to about 100% by weight of the total composition. In some embodiments, the purified polypeptide of the present disclosure is from about 75% to about 99% by weight pure, from about 80% to about 99% by weight pure, from about 90 to about 99% by weight pure, or from about 95% to about 99% by weight pure.

As used herein, the terms “subject,” “individual,” “host,” and “patient,” are used interchangeably herein and refer to any mammalian subject for whom diagnosis, treatment, or therapy is desired, particularly humans. The methods described herein are applicable to both human therapy and veterinary applications. In some embodiments, the subject is a mammal, and in other embodiments the subject is a human.

The term “therapeutic effect” as used herein is meant to refer to some extent of relief of one or more of the symptoms of a disorder (e.g., HIV infection) or its associated pathology. A “therapeutically effective amount” as used herein is meant to refer to an amount of an agent which is effective, upon single or multiple dose administration to the cell or subject, in prolonging the survivability of the patient with such a disorder, reducing one or more signs or symptoms of the disorder, preventing or delaying, and the like beyond that expected in the absence of such treatment. A “therapeutically effective amount” is intended to qualify the amount required to achieve a therapeutic effect. A physician or veterinarian having ordinary skill in the art can readily determine and prescribe the “therapeutically effective amount” (e.g., ED50) of the pharmaceutical composition required. For example, the physician or veterinarian could start doses of the compounds of the present disclosure employed in a pharmaceutical composition at levels lower than that required in order to achieve the desired therapeutic effect and gradually increase the dosage until the desired effect is achieved.

The terms “treat,” “treated,” “treating,” “treatment,” and the like as used herein are meant to refer to reducing or ameliorating a disorder and/or symptoms associated therewith (e.g., a viral infection). “Treating” may refer to administration of the DNA vaccines described herein to a subject after the onset, or suspected onset, of a viral infection. “Treating” includes the concepts of “alleviating”, which refers to lessening the frequency of occurrence or recurrence, or the severity, of any symptoms or other ill effects related to a virus and/or the side effects associated with viral therapy. The term “treating” also encompasses the concept of “managing” which refers to reducing the severity of a particular disease or disorder in a patient or delaying its recurrence, e.g., lengthening the period of remission in a patient who had suffered from the disease. It is appreciated that, although not precluded, treating a disorder or condition does not require that the disorder, condition, or symptoms associated therewith be completely eliminated.

For any therapeutic agent described herein the therapeutically effective amount may be initially determined from preliminary in vitro studies and/or animal models. A therapeutically effective dose may also be determined from human data. The applied dose may be adjusted based on the relative bioavailability and potency of the administered agent Adjusting the dose to achieve maximal efficacy based on the methods described above and other well-known methods is within the capabilities of the ordinarily skilled artisan. General principles for determining therapeutic effectiveness, which may be found in Chapter 1 of Goodman and Gilman's The Pharmacological Basis of Therapeutics, 10th Edition, McGraw-Hill (New York) (2001), incorporated herein by reference, are summarized below. Pharmacokinetic principles provide a basis for modifying a dosage regimen to obtain a desired degree of therapeutic efficacy with a minimum of unacceptable adverse effects. In situations where the drug's plasma concentration can be measured and related to the therapeutic window, additional guidance for dosage modification can be obtained. Drug products are considered to be pharmaceutical equivalents if they contain the same active ingredients and are identical in strength or concentration, dosage form, and route of administration. Two pharmaceutically equivalent drug products are considered to be bioequivalent when the rates and extents of bioavailability of the active ingredient in the two products are not significantly different under suitable test conditions.

The terms “polynucleotide,” “oligonucleotide” and “nucleic acid” are used interchangeably throughout and include DNA molecules (e.g., cDNA or genomic DNA), RNA molecules (e.g., mRNA), analogs of the DNA or RNA generated using nucleotide analogs (e.g., peptide nucleic acids and non-naturally occurring nucleotide analogs), and hybrids thereof. The nucleic acid molecule can be single-stranded or double-stranded. In some embodiments, the nucleic acid molecules of the disclosure comprise a contiguous open reading frame encoding an antibody, or a fragment thereof, as described herein. “Nucleic acid” or “oligonucleotide” or “polynucleotide” as used herein may mean at least two nucleotides covalently linked together. The depiction of a single strand also defines the sequence of the complementary strand. Thus, a nucleic acid also encompasses the complementary strand of a depicted single strand. Many variants of a nucleic acid may be used for the same purpose as a given nucleic acid. Thus, a nucleic acid also encompasses substantially identical nucleic acids and complements thereof. A single strand provides a probe that may hybridize to a target sequence under stringent hybridization conditions. Thus, a nucleic acid also encompasses a probe that hybridizes under stringent hybridization conditions. Nucleic acids may be single stranded or double stranded, or may contain portions of both double stranded and single stranded sequence. The nucleic acid may be DNA, both genomic and cDNA, RNA, or a hybrid, where the nucleic acid may contain combinations of deoxyribo- and ribo-nucleotides, and combinations of bases including uracil, adenine, thymine, cytosine, guanine, inosine, xanthine hypoxanthine, isocytosine and isoguanine Nucleic acids may be obtained by chemical synthesis methods or by recombinant methods. A nucleic acid will generally contain phosphodiester bonds, although nucleic acid analogs maybe included that may have at least one different linkage, e.g., phosphoramidate, phosphorothioate, phosphorodithioate, or O-methylphosphoroamidite linkages and peptide nucleic acid backbones and linkages. Other analog nucleic acids include those with positive backbones; non-ionic backbones, and non-ribose backbones, including those described in U.S. Pat. Nos. 5,235,033 and 5,034,506, which are incorporated by reference in their entireties. Nucleic acids containing one or more non-naturally occurring or modified nucleotides are also included within one definition of nucleic acids. The modified nucleotide analog may he located for example at the 5′-end and/or the 3′-end of the nucleic acid molecule. Representative examples of nucleotide analogs may be selected from sugar- or backbone-modified ribonucleotides. It should be noted, however, that also nucleobase-modified ribonucleotides, i.e. ribonucleotides, containing a non-naturally occurring nucleobase instead of a naturally occurring nucleobase such as uridines or cytidines modified at the 5-position, e.g. 5-(2-amino)propyl uridine, 5-bromo uridine; adenosines and guanosines modified at the 8-position, e.g. 8-bromo guanosine; deaza nucleotides, e.g. 7-deaza-adenosine; O- and N-alkylated nucleotides, e.g. N6-methyl adenosine are suitable. The 2′-OH-group may be replaced by a group selected from H, OR, R, halo, SH, SR, NH.sub.2, NHR, N.sub.2 or CN, wherein R is C.sub.1-C.sub.6 alkyl, alkenyl or alkynyl and halo is F, Cl, Br or I. Modified nucleotides also include nucleotides conjugated with cholesterol through, e.g., a hydroxyprolinol linkage as described in Krutzfeldt et al., Nature (Oct. 30, 2005), Soutschek et al., Nature 432:173-178 (2004), and U.S. Patent Publication No. 20050107325, which are incorporated herein by reference in their entireties. Modified nucleotides and nucleic acids may also include locked nucleic acids (LNA), as described in U.S. Patent No. 20020115080, which is incorporated herein by reference. Additional modified nucleotides and nucleic acids are described in U.S. Patent Publication No. 20050182005, which is incorporated herein by reference in its entirety. Modifications of the ribose-phosphate backbone may be done for a variety of reasons, e.g., to increase the stability and half-life of such molecules in physiological environments, to enhance diffusion across cell membranes, or as probes on a biochip. Mixtures of naturally occurring nucleic acids and analogs may be made; alternatively, mixtures of different nucleic acid analogs, and mixtures of naturally occurring nucleic acids and analogs may be made. In some embodiments, the expressible nucleic acid sequence is in the form of DNA. In some embodiments, the expressible nucleic acid is in the form of RNA with a sequence that encodes the polypeptide sequences disclosed herein and, in some embodiments, the expressible nucleic acid sequence is an RNA/DNA hybrid molecule that encodes any one or plurality of polypeptide sequences disclosed herein.

As used herein, the term “nucleic acid molecule” is a molecule that comprises one or more nucleotide sequences that encode one or more proteins. In some embodiments, a nucleic acid molecule comprises initiation and termination signals operably linked to regulatory elements including a promoter and polyadenylation signal capable of directing expression in the cells of the individual to whom the nucleic acid molecule is administered. In some embodiments, the nucleic acid molecule also includes a plasmid containing one or more nucleotide sequences that encode one or a plurality of viral antigens. In some embodiments, the disclosure relates to a pharmaceutical composition comprising a first, second, third or more nucleic acid molecule, each of which encoding one or a plurality of viral antigens and at least one of each plasmid comprising one or more of the compositions disclosed herein.

The terms “polypeptide”, “peptide” and “protein” are used interchangeably herein to refer to polymers of amino acids of any length. The polymer may be linear or branched, it may comprise modified amino acids, and it may be interrupted by non-natural amino acids or chemical groups that are not amino acids. The terms also encompass an amino acid polymer that has been modified; for example, disulfide bond formation, glycosylation, lipidation, acetylation, phosphorylation, or any other manipulation, such as conjugation with a labeling component. As used herein the term “amino acid” includes natural and/or unnatural or synthetic amino acids, including glycine and both the D or L optical isomers, and amino acid analogs and peptidomimetics.

The “percent identity” or “percent homology” of two polynucleotide or two polypeptide sequences is determined by comparing the sequences using the GAP computer program (a part of the GCG Wisconsin Package, version 10.3 (Accelrys, San Diego, Calif.)) using its default parameters. “Identical” or “identity” as used herein in the context of two or more nucleic acids or amino acid sequences, may mean that the sequences have a specified percentage of residues that are the same over a specified region. The percentage may be calculated by optimally aligning the two sequences, comparing the two sequences over the specified region, determining the number of positions at which the identical residue occurs in both sequences to yield the number of matched positions, dividing the number of matched positions by the total number of positions in the specified region, and multiplying the result by 100 to yield the percentage of sequence identity. In cases where the two sequences are of different lengths or the alignment produces one or more staggered ends and the specified region of comparison includes only a single sequence, the residues of single sequence are included in the denominator but not the numerator of the calculation. When comparing DNA and RNA, thymine (T) and uracil (U) may be considered equivalent. Identity may he performed manually or by using a computer sequence algorithm such as BLAST or BLAST 2.0. Briefly, the BLAST algorithm, which stands for Basic Local Alignment Search Tool is suitable for determining sequence similarity. Software for performing BLAST analyses is publicly available through the National Center for Biotechnology Information (http://www.ncbi.nlm.nih.gov). This algorithm involves first identifying high scoring sequence pair (HSPs) by identifying short words of length Win the query sequence that either match or satisfy some positive-valued threshold score T when aligned with a word of the same length in a database sequence. T is referred to as the neighborhood word score threshold (Altschul et al., supra). These initial neighborhood word hits act as seeds for initiating searches to find HSPs containing them. The word hits are extended in both directions along each sequence for as far as the cumulative alignment score can be increased. Extension for the word hits in each direction are halted when: 1) the cumulative alignment score falls off by the quantity X from its maximum achieved value; 2) the cumulative score goes to zero or below, due to the accumulation of one or more negative-scoring residue alignments; or 3) the end of either sequence is reached. The Blast algorithm parameters W, T and X determine the sensitivity and speed of the alignment. The Blast program uses as defaults a word length (W) of 11, the BLOSUM62 scoring matrix (see Henikoff et al., Proc. Natl. Acad. Sci. USA, 1992, 89, 10915-10919, which is incorporated herein by reference in its entirety) alignments (B) of 50, expectation (E) of 10, M=5, N=4, and a comparison of both strands. The BLAST algorithm (Karlin et al., Proc. Natl. Acad. Sci. USA, 1993, 90, 5873-5787, which is incorporated herein by reference in its entirety) and Gapped BLAST perform a statistical analysis of the similarity between two sequences. One measure of similarity provided by the BLAST algorithm is the smallest sum probability (P(N)), which provides an indication of the probability by which a match between two nucleotide sequences would occur by chance. For example, a nucleic acid is considered similar to another if the smallest sum probability in comparison of the test nucleic acid to the other nucleic acid is less than about 1, less than about 0.1, less than about 0.01, and less than about 0.001. Two single-stranded polynucleotides are “the complement” of each other if their sequences can be aligned in an anti-parallel orientation such that every nucleotide in one polynucleotide is opposite its complementary nucleotide in the other polynucleotide, without the introduction of gaps, and without unpaired nucleotides at the 5′ or the 3′ end of either sequence. A polynucleotide is “complementary” to another polynucleotide if the two polynucleotides can hybridize to one another under moderately stringent conditions. Thus, a polynucleotide can be complementary to another polynucleotide without being its complement.

By “substantially identical” is meant nucleic acid molecule (or polypeptide) exhibiting at least 50% identity to a reference amino acid sequence (for example, any one of the amino acid sequences described herein) or nucleic acid sequence (for example, any one of the nucleic acid sequences described herein). Preferably, such a sequence is at least 60%, more preferably 80% or 85%, and more preferably 90%, 95% or even 99% identical at the amino acid level or nucleic acid to the sequence used for comparison.

A nucleotide sequence is “operably linked” to a regulatory sequence if the regulatory sequence affects the expression (e.g., the level, timing, or location of expression) of the nucleotide sequence. A “regulatory sequence” is a nucleic acid that affects the expression (e.g., the level, timing, or location of expression) of a nucleic acid to which it is operably linked. The regulatory sequence can, for example, exert its effects directly on the regulated nucleic acid, or through the action of one or more other molecules (e.g., polypeptides that bind to the regulatory sequence and/or the nucleic acid). Examples of regulatory sequences include promoters, enhancers and other expression control elements (e.g., polyadenylation signals). Further examples of regulatory sequences are described in, for example, Goeddel, 1990, Gene Expression Technology: Methods in Enzymology 185, Academic Press, San Diego, Calif. and Baron et al., 1995, Nucleic Acids Res. 23:3605-06.

A “vector” is a nucleic acid that can be used to introduce another nucleic acid linked to it into a cell. One type of vector is a “plasmid,” which refers to a linear or circular double stranded DNA molecule into which additional nucleic acid segments can be ligated. Another type of vector is a viral vector (e.g., replication defective retroviruses, adenoviruses and adeno-associated viruses), wherein additional DNA segments can be introduced into the viral genome. Certain vectors are capable of autonomous replication in a host cell into which they are introduced (e.g., bacterial vectors comprising a bacterial origin of replication and episomal mammalian vectors). Other vectors (e.g., non-episomal mammalian vectors) are integrated into the genome of a host cell upon introduction into the host cell, and thereby are replicated along with the host genome. An “expression vector” is a type of vector that can direct the expression of a chosen polynucleotide. The disclosure relates to any one or plurality of vectors that comprise nucleic acid sequences encoding any one or plurality of amino acid sequence disclosed herein.

The term “vaccine” as used herein is meant to refer to a composition for generating immunity for the prophylaxis and/or treatment of diseases (e.g., viral infections). Accordingly, vaccines are medicaments which comprise antigens in protein and/or nucleic acid forms and are intended to be used in humans or animals for generating specific defense and protective substance by vaccination. A “vaccine composition” or a “DNA vaccine composition” can include a pharmaceutically acceptable excipient, earner or diluent.

Ranges may be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, also specifically contemplated and considered disclosed is the range from the one particular value and/or to the other particular value unless the context specifically indicates otherwise. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another, specifically contemplated embodiment that should be considered disclosed unless the context specifically indicates otherwise. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint unless the context specifically indicates otherwise. The term “about” as used herein when referring to a measurable value such as an amount, a temporal duration, and the like, is meant to encompass variations of ±20%, ±10%, ±5%, ±1%, ±0.5%, or ±0.1% from the specified value, as such variations are appropriate to perform the disclosed methods.

“Variants” is intended to mean substantially similar sequences. For nucleic acid molecules, a variant comprises a nucleic acid molecule having deletions (i.e., truncations) at the 5′ and/or 3′ end; deletion and/or addition of one or more nucleotides at one or more internal sites in the native polynucleotide; and/or substitution of one or more nucleotides at one or more sites in the native polynucleotide. As used herein, a “native” nucleic acid molecule or polypeptide comprises a naturally occurring nucleotide sequence or amino acid sequence, respectively. For nucleic acid molecules, conservative variants include those sequences that, because of the degeneracy of the genetic code, encode the amino acid sequence of one of the polypeptides of the disclosure. Variant nucleic acid molecules also include synthetically derived nucleic acid molecules, such as those generated, for example, by using site-directed mutagenesis but which still encode a protein of the disclosure. Generally, variants of a particular nucleic acid molecule of the disclosure will have at least about 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to that particular polynucleotide as determined by sequence alignment programs and parameters as described elsewhere herein. Variants of a particular nucleic acid molecule of the disclosure (i.e., the reference DNA sequence) can also be evaluated by comparison of the percent sequence identity between the polypeptide encoded by a variant nucleic acid molecule and the polypeptide encoded by the reference nucleic acid molecule. Percent sequence identity between any two polypeptides can be calculated using sequence alignment programs and parameters described elsewhere herein. Where any given pair of nucleic acid molecule of the disclosure is evaluated by comparison of the percent sequence identity shared by the two polypeptides that they encode, the percent sequence identity between the two encoded polypeptides is at least about 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity. In some embodiments, the term “variant” protein is intended to mean a protein derived from the native protein by deletion (so-called truncation) of one or more amino acids at the N-terminal and/or C-terminal end of the native protein; deletion and/or addition of one or more amino acids at one or more internal sites in the native protein; or substitution of one or more amino acids at one or more sites in the native protein. Variant proteins encompassed by the present disclosure are biologically active, that is they continue to possess the desired biological activity of the native protein as described herein. Such variants may result from, for example, genetic polymorphism or from human manipulation. Biologically active variants of a protein of the disclosure will have at least about 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or more sequence identity to the amino acid sequence for the native protein as determined by sequence alignment programs and parameters described elsewhere herein. A biologically active variant of a protein of the disclosure may differ from that protein by as few as 1-15 amino acid residues, as few as 1-10, such as 6-10, as few as 5, as few as 4, 3, 2, or even 1 amino acid residue. The proteins or polypeptides of the disclosure may be altered in various ways including amino acid substitutions, deletions, truncations, and insertions. Methods for such manipulations are generally known in the art. For example, amino acid sequence variants and fragments of the proteins can be prepared by mutations in the nucleic acid sequence that encode the amino acid sequence recombinantly.

Finally, it should be understood that all of the individual values and sub-ranges of values contained within an explicitly disclosed range are also specifically contemplated and should be considered disclosed unless the context specifically indicates otherwise. The foregoing applies regardless of whether in particular cases some or all of these embodiments are explicitly disclosed.

The terms “subject,” “individual,” and “patient” are used interchangeably herein to refer to a vertebrate, preferably a mammal, more preferably a human. Mammals include, but are not limited to, murines, simians, humans, farm animals, cows, pigs, goats, sheep, horses, dogs, sport animals, and pets. Tissues, cells and their progeny obtained in vivo or cultured in vitro are also encompassed by the definition of the term “subject.” The term “subject” is also used throughout the specification in some embodiments to describe an animal from which a cell sample is taken or an animal to which a disclosed cell or nucleic acid sequences have been administered. In some embodiment, the animal is a human. For treatment of those conditions which are specific for a specific subject, such as a human being, the term “patient” may be interchangeably used. In some instances in the description of the present disclosure, the term “patient” will refer to human patients suffering from a particular disease or disorder. In some embodiments, the subject may be a non-human animal from which an endothelial cell sample is isolated or provided. The term “mammal” encompasses both humans and non-humans and includes but is not limited to humans, non-human primates, canines, felines, murines, bovines, equines, caprines, and porcines.

Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of skill in the art to which the disclosed method and compositions belong. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present method and compositions, the particularly useful methods, devices, and materials are as described. Publications cited herein and the material for which they are cited are hereby specifically incorporated by reference. Nothing herein is to be construed as an admission that the present disclosure is not entitled to antedate such disclosure by virtue of prior disclosure. No admission is made that any reference constitutes prior art. The discussion of references states what their authors assert, and applicants reserve the right to challenge the accuracy and pertinency of the cited documents. It will be clearly understood that, although a number of publications are referred to herein, such reference does not constitute an admission that any of these documents forms part of the common general knowledge in the art.

Throughout the description and claims of this specification, the word “comprise” and variations of the word, such as “comprising” and “comprises,” means “including but not limited to,” and is not intended to exclude, for example, other additives, components, integers or steps. In particular, in methods stated as comprising one or more steps or operations it is specifically contemplated that each step comprises what is listed (unless that step includes a limiting term such as “consisting of”), meaning that each step is not intended to exclude, for example, other additives, components, integers or steps that are not listed in the step.

4. Viral Antigens

The disclosure relates to one or a plurality of nucleic acid molecules that comprise at least one expressible nucleic acid sequence, the expressible nucleic acid sequence comprises a first nucleic acid sequence encoding a self-assembling polypeptide and a second nucleic acid sequence encoding a viral antigen. In some embodiments, the nucleic acid molecule encodes a fusion peptide comprising one or a plurality of self-assembling peptides and one or a plurality of viral antigens. In some embodiments, upon administration to a subject, the composition comprising a nucleic acid comprising the expressible nucleic acid sequence is transfected or transduced into an antigen presenting cell which encodes the expressible nucleic acid sequence. After a plurality of expressible nucleic acid sequences are encoded, the self-assembling peptides assemble into a nanoparticle comprising the one or plurality of viral antigens. Antigen presenting cells expressing the one or plurality of viral antigens can elicit a therapeutically effective antigen-specific immune response against the virus in a subject. In some embodiments, the viral antigen can be an antigen from a Retroviridae or Flavivirus. For example, in some embodiments, the viral antigen can be an antigen from human immunodeficiency virus-1 (HIV-1). In some embodiments, the viral antigen comprises at least 70% sequence identity to SEQ ID NO: 4 or a pharmaceutically acceptable salt thereof. SEQ ID NO:4 is a fragment of gp120 represented by the nucleic acid sequence:

5. Regulatory Sequences

In some embodiments, the expressible nucleic acid sequence can be operably linked to one or a plurality of regulatory sequences.

B. Nucleic Acid Molecule

In one aspect, the present disclosure also relates to a nucleic acid molecule that comprises any of the disclosed expressible nucleic acid sequences. For example, the nucleic acid molecule can be a plasmid. Provided herein is a vector or plasmid that is capable of expressing a at least a monomer of a self-assembling nanoparticle and a viral antigen construct or constructs in the cell of a mammal in a quantity effective to elicit an immune response in the mammal. The vector may comprise heterologous nucleic acid encoding the one or more viral antigens (such as HIV-1 antigens). The vector may be a plasmid. The plasmid may be useful for transfecting cells with nucleic acid encoding a viral antigen, which the transformed host cell is cultured and maintained under conditions wherein expression of the viral antigen takes place and wherein the structure of the nanoparticle with the antigen elicits an immune response of a magnitude greater than and/or more therapeutically effective than the immune response elicited by the antigen alone. The plasmid may further comprise an initiation codon, which may be upstream of the expressible sequence, and a stop codon, which may be downstream of the coding sequence. The initiation and termination codon may be in frame with the expressible sequence.

The plasmid may also comprise a promoter that is operably linked to the coding sequence The promoter operably linked to the coding sequence may be a promoter from simian virus 40 (SV40), a mouse mammary tumor virus (MMTV) promoter, a human immunodeficiency virus (HIV) promoter such as the bovine immunodeficiency virus (BIV) long terminal repeat (LTR) promoter, a Moloney virus promoter, an avian leukosis virus (ALV) promoter, a cytomegalovirus (CMV) promoter such as the CMV immediate early promoter, Epstein Barr virus (EBV) promoter, or a Rous sarcoma virus (RSV) promoter. The promoter may also be a promoter from a human gene such as human actin, human myosin, human hemoglobin, human muscle creatine, or human metalothionein. The promoter may also be a tissue specific promoter, such as a muscle or skin specific promoter, natural or synthetic. Examples of such promoters are described in US patent application publication no. US20040175727, the contents of which are incorporated herein in its entirety. The plasmid may also comprise a polyadenylation signal, which may be downstream of the coding sequence. The polyadenylation signal may be a SV40 polyadenylation signal, LTR polyadenylation signal, bovine growth hormone (bGH) polyadenylation signal, human growth hormone (hGH) polyadenylation signal, or human β-globin polyadenylation signal. The SV40 polyadenylation signal may be a polyadenylation signal from a pCEP4 plasmid (Invitrogen, San Diego, Calif.).

The plasmid may also comprise an enhancer upstream of the coding sequence. The enhancer may be human actin, human myosin, human hemoglobin, human muscle creatine or a viral enhancer such as one from CMV, FMDV, RSV or EBV. Polynucleotide function enhancers are described in U.S. Pat. Nos. 5,593,972, 5,962,428, and WO94/016737, the contents of each are fully incorporated by reference. The plasmid may also comprise a mammalian origin of replication in order to maintain the plasmid extrachromosomally and produce multiple copies of the plasmid in a cell. The plasmid may be pVAX1, pCEP4 or pREP4 from ThermoFisher Scientific (San Diego, Calif.), which may comprise the Epstein Barr virus origin of replication and nuclear antigen EBNA-1 coding region, which may produce high copy episomal replication without integration. The vector can be pVAX1 or a pVax1 variant with changes such as the variant plasmid described herein. The variant pVax1 plasmid is a 2998 basepair variant of the backbone vector plasmid pVAX1 (Invitrogen, Carlsbad Calif.). The CMV promoter is located at bases 137-724. The T7 promoter/priming site is at bases 664-683. Multiple cloning sites are at bases 696-811. Bovine GH polyadenylation signal is at bases 829-1053. The Kanamycin resistance gene is at bases 1226-2020. The pUC origin is at bases 2320-2993. The vaccine may comprise the consensus antigens and plasmids at quantities of from about 1 nanogram to 100 milligrams; about 1 microgram to about 10 milligrams; or preferably about 0.1 microgram to about 10 milligrams; or more preferably about 1 milligram to about 2 milligram. In some embodiments, pharmaceutical compositions according to the present disclosure comprise from about 1 nanogram to about 1000 micrograms of DNA. The nucleic acid sequence for the pVAX1 backbone sequence is as follows:

The electroporation component may be capable of delivering the pulse of energy that produces the constant current in the desired tissue, and includes a feedback mechanism. The electrode assembly may include an electrode array having a plurality of electrodes in a spatial arrangement, wherein the electrode assembly receives the pulse of energy from the electroporation component and delivers same to the desired tissue through the electrodes. At least one of the plurality of electrodes is neutral during delivery of the pulse of energy and measures impedance in the desired tissue and communicates the impedance to the electroporation component. The feedback mechanism may receive the measured impedance and can adjust the pulse of energy delivered by the electroporation component to maintain the constant current.

A plurality of electrodes may deliver the pulse of energy in a decentralized pattern. The plurality of electrodes may deliver the pulse of energy in the decentralized pattern through the control of the electrodes under a programmed sequence, and the programmed sequence is input by a user to the electroporation component. The programmed sequence may comprise a plurality of pulses delivered in sequence, wherein each pulse of the plurality of pulses is delivered by at least two active electrodes with one neutral electrode that measures impedance, and wherein a subsequent pulse of the plurality of pulses is delivered by a different one of at least two active electrodes with one neutral electrode that measures impedance.

The feedback mechanism may be performed by either hardware or software. The feedback mechanism may be performed by an analog closed-loop circuit. The feedback occurs every 50 μs, 20 μs, 10 μs or 1 μs, but is preferably a real-time feedback or instantaneous (i.e., substantially instantaneous as determined by available techniques for determining response time). The neutral electrode may measure the impedance in the desired tissue and communicates the impedance to the feedback mechanism, and the feedback mechanism responds to the impedance and adjusts the pulse of energy to maintain the constant current at a value similar to the preset current. The feedback mechanism may maintain the constant current continuously and instantaneously during the delivery of the pulse of energy.

The cell lysate suspension is then allowed to flow into a bubble-mixer chamber for precipitation of cellular components from the plasmid DNA. In the bubble mixer chamber, the cell lysate suspension and a precipitation solution or a neutralization solution from a third tank are mixed together using gas bubbles, which forms a mixed gas suspension comprising a precipitate and an unclarified lysate or plasmid containing fluid. The precipitate of the mixed gas suspension is less dense than the plasmid containing fluid, which facilitates the separation of the precipitate from the plasmid containing fluid. The precipitate is removed from the mixed gas suspension to give a clarified lysate having the plasmid DNA, and the precipitate having cellular debris and genomic DNA.

In some embodiments, the bubble mixer-chamber comprises a closed vertical column with a top, a bottom, a first, and a second side with a vent proximal to the top of the column. A first inlet port of the bubble mixer-chamber is on the first side proximal to the bottom of the column and in fluid communication with the holding coil. A second inlet port of the bubble mixer-chamber is proximal to the bottom on a second side opposite of the first inlet port and in fluid communication with a third tank, wherein the third tank is used for holding a precipitation or a neutralization solution. A third inlet port of the bubble mixer-chamber is proximal to the bottom of the column and about in the middle of the first and second inlets and is in fluid communication with a gas source the third inlet entering the bubble-mixer-chamber. A preferred embodiment utilizes a sintered sparger inside the closed vertical column of the third inlet port. The outlet port exiting the bubble mixing chamber is proximal to the top of the closed vertical column. The outlet port is in fluid communication with a fourth tank, wherein the mixed gas suspension containing the plasmid DNA is allowed to flow from the bubble-mixer-chamber into the fourth tank. The fourth tank is used for separating the precipitate of the mixed gas suspension having a plasmid containing fluid, and can also include an impeller mixer sufficient to provide uniform mixing of fluid without disturbing the precipitate. A fifth tank is used for a holding the clarified lysate or clarified plasmid containing fluid. The clarified lysate is then filtered at least once. A first filter has a particle size limit of about 5-10 μm and the second filter has a cut of about 0.2 μm. Although gravity, pressure, vacuum, or a mixture thereof can be used for transporting: suspension of cells; lysis solutions; precipitation solutions; neutralization solutions; or mixed gas suspensions from any of the tanks to mixers, holding coils or different tanks, pumps are utilized in a preferred embodiments. In a more preferred embodiment, at least one pump having a linear flow rate from about 0.1 to about 1 ft/second is used.

In another specific embodiment, a Y-connector having a having a first bifurcated branch, a second bifurcated branch and an exit branch is used to contact the cell suspension and the lysis solutions before they enter the high shear, low residence-time mixing device. The first tank holding the cell suspension is in fluid communication with the first bifurcated branch of the Y-connector through the first pump and the second tank holding the lysis solution is in fluid communication with the second bifurcated branch of the Y-connector through the second pump. The high shear, low residence-time mixing device is in fluid communication with an exit branch of the Y-connector, wherein the first and second pumps provide a linear flow rate of about 0.1 to about 2 ft/second for a contacted fluid exiting the Y-connector.

Another specific aspect of the present disclosure is a method of substantially separating plasmid DNA and genomic DNA from a bacterial cell lysate. The method comprises: delivering a cell lysate into a chamber; delivering a precipitation fluid or a neutralization fluid into the chamber; mixing the cell lysate and the precipitation fluid or a neutralization fluid in the chamber with gas bubbles forming a gas mixed suspension, wherein the gas mixed suspension comprises the plasmid DNA in a fluid portion (i.e. an unclarified lysate) and the genomic DNA is in a precipitate that is less dense than the fluid portion; floating the precipitate on top of the fluid portion; removing the fluid portion from the precipitate forming a clarified lysate, whereby the plasmid DNA in the clarified lysate is substantially separated from genomic DNA in the precipitate. In preferred embodiments: the chamber is the bubble mixing chamber as described above; the lysing solution comprises an alkali, an acid, a detergent, an organic solvent, an enzyme, a chaotrope, or a denaturant; the precipitation fluid or the neutralization fluid comprises potassium acetate, ammonium acetate, or a mixture thereof; and the gas bubbles comprise compressed air or an inert gas. Additionally, the decanted-fluid portion containing the plasmid DNA is preferably further purified with one or more purification steps selected from a group consisting of: ion exchange, hydrophobic interaction, size exclusion, reverse phase purification, endotoxin depletion, affinity purification, adsorption to silica, glass, or polymeric materials, expanded bed chromatography, mixed mode chromatography, displacement chromatography, hydroxyapatite purification, selective precipitation, aqueous two-phase purification, DNA condensation, thiophilic purification, ion-pair purification, metal chelate purification, filtration through nitrocellulose, or ultrafiltration.

In some embodiments, a method for isolating a plasmid DNA from cells comprising: mixing a suspension of cells having the plasmid DNA and genomic DNA with a lysis solution in a high-shear-low-residence-time-mixing-device for a first period of time forming a cell lysate fluid; incubating the cell lysate fluid for a second period of time in a holding coil forming a cell lysate suspension; delivering the cell lysate suspension into a chamber; delivering a precipitation/neutralization fluid into the chamber; mixing the cell lysate suspension and the a precipitation/neutralization fluid in the chamber with gas bubbles forming a gas mixed suspension, wherein the gas mixed suspension comprises an unclarified lysate containing the plasmid DNA and a precipitate containing the genomic DNA, wherein the precipitate is less dense than the unclarified lysate; floating the precipitate on top of the unclarified lysate; removing the precipitate from the unclarified lysate forming a clarified lysate, whereby the plasmid DNA is substantially separated from genomic DNA; precipitating the plasmid DNA from the clarified lysate forming a precipitated plasmid DNA; and resuspending the precipitated plasmid DNA in an aqueous solution.
