摘要:
Embodiments of the present disclosure encompasses virus-like particles, methods of making virus-like particles, including expression vectors, wherein the virus- like particles may comprise enhanced levels of capsid-bound a chimeric HN-Env polypeptide compared to VLPs derived from unmodified HIV-env polypeptides. Embodiments of the virus-like particle may have Env -specific epitopes exposed on the outer surface thereof. In one embodiment, the Env -specific epitopes exposed on the outer surface of the virus-like particle may specifically bind with an anti-HIV-Env specific antibody. Embodiments of the disclosure further includes methods of generating an antibody specific to an epitope of an HIV-Eny polypeptide, comprising delivering to an animal or a human an effective amount of a suspension of virus-like particles comprising a chimeric HIV-Env polypeptide, thereby inducing the formation of an antibody specific to an epitope of an HIV-1 eny polypeptide.
摘要:
The invention provides a lentiviral envelope polypeptide or a nucleic acid sequence encoding a lentiviral envelope polypeptide, which are capable of inducing an immunogenic response against lentiviral infection, such as HIV infection. Examples of envelopes are HIV-1, HIV-2 or SIV envelope proteins or variants thereof. A specific such envelope variant is devoid of its C-terminal domain. The lentiviral envelope polypeptide or nucleic acid encoding said polypeptide is provided in vectors, methods, proviruses, retroviral particles, uses, compositions, vaccines, vaccine compositions and kits. Moreover, the lentiviral envelope polypeptide or nucleic acid encoding said polypeptide may be provided in combination with other compounds, such as selective marker genes, adjuvants, and immunomodulating agents. The invention is applicable for generation of retroviral particles for specific targeting of host cells. The retroviral particles may be used for integration of trangenes in host cells and induction of an immunogenic response, for example against HIV-1.

摘要:
Compositions and methods for eliciting an immune response against HIV and/or SIV are provided. Isolated gpl20 proteins having two or more amino acids deleted from their ß3-ß5 loop regions and isolated nucleic acid sequences encoding a gpl20 protein having two or more amino acids deleted from its ß3-ß5 loop region are also provided.
摘要:
The invention relates to lipopeptide building blocks consisting of a peptide chain comprising a coiled-coil domain, linked covalently to a lipid moiety comprising long alkyl or alkenyl chains, and optionally linked to an antigen; and to helical lipopeptide bundles and synthetic virus-like particles formed by aggregation. The nanometer size and shape of these bundles and particles, their stability under aqueous physiological conditions, their chemical composition, the possibility to incorporate B- and T-cell epitopes, and their production by chemical synthesis, make them highly suitable as vaccine delivery vehicles.
摘要:
This invention discloses immunostimulatory combinations of Tumor Necrosis Factor Receptor Superfamily (TNFRSF) agonists, Toll-Like Receptor (TLR) agonists, "domain present in NAIP,CIITA, HET-E, TP-I (NACHT)-Leucine Rich Repeat (LRR)" or "NLR" agonists, RIG-I-Like Helicase or "RLH" agonists, purinergic receptor agonists and cytokine/chemokine receptor agonists, together with delivery methods. The combinations, when used alone at the site of pathology, provide immunostimulation that induces host humoral and cellular immunologic responses to eliminate pathogens or neoplasms. Alternatively, when the combinations are used with a defined antigens, these combinations can induce focused humoral and cellular immunologic responses useful as prophylactic and/or ameliorative therapeutic modalities for infections and the treatment of neoplastic disorders.
摘要:
The present invention relates, in general, to human immunodeficiency virus (HIV) and, in particular, to a multicomponent vaccine and method of using same to protect against HTV-I infection.
摘要:
The present invention provides a polypeptide immunoconjugate comprising an antigenic polypeptide which is coupled to a polypeptide which is capable of binding to an Fc receptor. The antigenic polypeptide is derived from a pathogen or a pathogen product and as characterised in that it can be processed by the immune system in order to generate an immune response there against which confers protective immunity against the pathogen from which the antigenic polypeptide is derived. The invention further extends to methods for the treatment of a disease condition in a subject using the immunoconjugate of the invention.
