摘要:
The invention is directed to peptides of the HIV-1 envelope protein presenting multiple immune determinants. The peptide elicits both humoral and cell-mediated immune responses in mice having a variety of MHC types. In other embodiments, the invention is directed to immunogens composed of the peptides and methods for immunization employing them.
摘要:
This invention is directed toward a multideterminant human immunodeficiency virus type 1 (HIV-1) peptide which comprises a covalently linked T-helper (Th) lymphocyte epitope, cytotoxic T-lymphocyte (CTL) epitope, and an epitope capable of eliciting a neutralizing antibody response (AbN), wherein said peptide has the following amino acid sequence: KQIINMWQEVGKAMYAPPISGQIRRIHIGPGRAFYTTKN. This peptide has the further characteristic of evoking all three of these immune responses in hosts having a broad range of major histocompatibility complex (MHC) types. This peptide is useful as an immunogen to generate broad immune responses in a host, to assess immune responses in virally infected hosts, and as a diagnostic reagent to detect viral infection.
