摘要:
The instant application provides methods and related compositions pertaining to novel HIV envelope proteins. In some embodiments, the invention relates to methods and compositions for the preparation, production, and administration of isolated novel HIV envelope nucleic acid and protein sequences suitable, for example, as vaccines against HIV.
摘要:
Transcutaneous immunization can deliver antigen to the immune system through the stratum corneum without physical or chemical penetration to the dermis layer of the skin. This delivery system induces an antigen-specific immune response. Use of skin-active adjuvants is preferred. Although perforation of intact skin is not required, superficial penetration or micropenetration of the skin can act as an enhancer; similarly, hydration may enhance the immune response. This system can induce antigen-specific immune effectors after epicutaneous application of a formulation containing one or more antigen and adjuvant. The formulation may initiate processes such as antigen uptake, processing, and presentation; Langerhans cell activation, migration from the skin to other immune organs, and differentiation to mature dendritic cells; contacting antigen with lymphocytes bearing cognate antigen receptors on the cell surface and their stimulation; and combinations thereof. Systemic and/or regional immunity may be induced; immune responses that result in prophylaxis and/or therapeutic treatments are preferred. Antigen and adjuvant activities in the formulation may be found in the same molecule, two or more different molecules dissociated from each other, or multiple molecules in a complex formed by covalent or non-covalent bonds. For antigens and adjuvants which are proteinaceous, they may be provided in the formulation as a polynucleotide for transcutaneous genetic immunization. Besides simple application of a liquid formulation, patches or other medical devices may be used to deliver antigen for immunization.

摘要:
A transcutaneous immunization system delivers antigen to immune cells without perforation of the skin, and induces an immune response in an animal or human. The system uses an adjuvant, preferably an ADP-ribosylating exotoxin, to induce an antigen-specific immune response (e.g., humoral and/or cellular effectors) after transcutaneous application of a formulation containing antigen and adjuvant to intact skin of the animal or human. The efficiency of immunization may be enhanced by adding hydrating agents (e.g., liposomes), penetration enhancers, or occlusive dressings to the transcutaneous delivery system. This system may allow activation of Langerhans cells in the skin, migration of the Langerhans cells to lymph nodes, and antigen presentation.
摘要:
A method is provided for inhibiting or preventing toxicity and other unwanted effects (a) caused by solvents for pharmaceuticals which solvents or emulsifier which contain amphiphilic molecules such as polyethoxylated oils or a derivative thereof, or (b) caused by a drug in a vehicle containing amphiphilic molecules such as phopholipids or derivative thereof, emplying a complement inhibitor. Drug compositions containing amphiphilic molecules, or derivatives thereof and a complement inhibitor, and pharmaceutical compositions including a drug, solvent or carrier containing amphiphilic molecules or derivatives thereof, and a complement inhibitor are also provided.
摘要:
Antibodies and method of making antibodies, either monoclonal or polyclonal wherein said antibodies have dual or multi-specific binding capacity to more than one type of antigenic epitope. The antibodies have simultaneous or independent recognition subsites to each of the epitopes. Antigenic epitopes include lipids, peptides, proteins, amino acid sequences, sugars and carbohydrates. Monoclonal antibodies and a method of making monoclonal antibodies of the invention include monoclonal antibodies that are broadly neutralizing to HIV-1 or other envelop viruses wherein the monoclonal antibody has subsites that simultaneously recognize protein and lipid epitopes from the virus.

摘要:
Transcutaneous immunization can deliver antigen to the immune system through the stratum corneum without physical or chemical penetration to the dermis layer of the skin. This delivery system induces an antigen-specific immune response without the use of a heterologous adjuvant. Although perforation of intact skin is not required, superficial penetration or micropenetration of the skin can act as an enhancer; similarly, hydration may enhance the immune response. This system can induce antigen-specific immune effectors after epicutaneous application of a formulation containing one or more antigens. The formulation may initiate processes such as antigen uptake, processing, and presentation; Langerhans cell activation, migration from the skin to other immune organs, and differentiation to mature dendritic cells; contacting antigen with lymphocytes bearing cognate antigen receptors on the cell surface and their stimulation; and combinations thereof. Systemic and/or regional immunity may be induced. Immune responses that provide prophylactic and/or therapeutic treatments are preferred. Antigenic activities in the formulation may be found in the same molecule, two or more different molecules dissociated from each other, or multiple molecules in a complex formed by covalent or non-covalent bonds. For antigens which are proteinaceous, they may be provided in the formulation as a polynucleotide for transcutaneous genetic immunization. Besides simple application of a dry or liquid formulation to the skin, patches and other medical devices may be used to deliver antigen for immunization.
摘要:
The invention relates to transcutaneous and/or transdermal transport of materials, such as antigens, drugs, drugs, nucleic acids, (e.g., DNA and RNA), proteins, other therapeutic agents, dyes, and the like, into the skin and/or the body. The material is transported transcutaneously and/or transdermally using an antigen presenting cell (APC) by applying the APC and the material on to the surface of the skin.
摘要:
A transcutaneous immunization system where the topical application of an adjuvant and an antigen or nucleic acid encoding for an antigen, to intact skin induces a systemic or mucosol antibody response. The immune response so elicited can be enhanced by physical or chemical skin penetration enhancement.
