摘要:
The invention provides compositions and methods to induce and boost antibody response, including but not limited to IgG responses binding to HIV-1 in a subject in need thereof, wherein the induced/boosted plasma level of the antibody responses, for example V3 and/or CD4 binding site antibody responses, is over a threshold level and is associated with reduced risk of maternal-to-child-transmission (MTCT) of HIV-1.
摘要:
The present invention relates, in general, to a method of inducing an immune response to HlV-1 in a mammal and, in particular, to a vaccine formulation suitable for use in such a method comprising an HIV-1 envelope (Env) immunogen comprising recombinant Envs with some degree of high- mannose glycan residues and a Toll-like receptor (TLR) agonist-supplemented squalene-based adjuvant.
摘要:
The invention features a novel influenza antibody that specifically binds to influenza hemagglutinin and reduces or inhibits hemagglutinin binding to sialic acid. The invention also provides methods, compositions, and kits featuring the novel antibody and its use in preventing or treating influenza infection.
摘要:
The present invention relates, in general, to human immunodeficiency virus (HIV), and in particular to a vaccine for HIV-1 and to methods of making and using same.
摘要:
Antibody VRC01 represents a human immunoglobulin that neutralizes—˜90% of diverse HIV-1 isolates. To understand how such broadly neutralizing HIV-1 antibodies develop and recognize the viral envelope, we used X-ray crystallography and 454 pyrosequencing to characterize additional antibodies from HIV-1-infected individuals. Crystal structures revealed a convergent mode of binding of different antibodies to the same CD4-binding-site epitope. Antibody recognition was achieved through the evolution of complementary contact domains that were generated in diverse ways. Phylogenetic analysis of expressed heavy and light chains determined by deep sequencing revealed a common pathway of antibody heavy chain maturation confined to IGHV1-2*02 lineage that could pair with different light chains. The maturation pathway inferred by antibodyomics reveals that diverse antibodies evolve to a highly affinity-matured state to recognize an invariant viral structure, providing insight into the development and evolution of broadly neutralizing HIV-1 immunity.
摘要:
The present invention relates, in general to herpes simplex virus (HSV) and, particular, to antibodies that are specific for glycoprotein D (gD) of HSV. The invention also relates to prophylactic and therapeutic uses of such antibodies.
摘要:
The present invention relates, in general, to animal models suitable for testing candidate immunogens and, in particular, to knock-in mice expressing heavy and light chains of membrane proximal external region (MPER) HIV-I broadly neutralizing antibodies and to methods of screening candidate immunogens using same.
摘要:
The present invention relates, in general, to HIV and, in particular to a method of detecting anti-HIV antibodies and antibody-HIV virion complexes.
摘要:
The present invention relates, in general, to thymic microenvironment and, in particular, to a method of producing a thymic microenvironment. The invention further relates to a method of treating congenital and acquired immunodeficiencies using a thymic microenvironment produced in vitro. Included in acquired immunodeficiencies are syndromes seen in malignant and autoimmune diseases as well as traditional T cell immunodeficiency diseases such as occurs in AIDS.
