Disclosed herein are mosaic conserved region HIV polypeptides and immunogenic polypeptides including one or more of the mosaic conserved region polypeptides. In some embodiments, the immunogenic polypeptides are included in an immunogenic composition, such as a polyvalent immunogenic composition. Also disclosed herein are methods for treating or inhibiting HIV in a subject including administering one or more of the disclosed immunogenic polypeptides or compositions to a subject having or at risk of HIV infection. In some embodiments, the methods include inducing an immune response in a subject comprising administering to the subject at least one of the disclosed immunogenic polypeptides or a nucleic acid encoding at least one of the immunogenic polypeptides.

Mosaic conserved region HIV immunogenic polypeptides

The present invention provides artificial fusion proteins (AFPs) designed to elicit an anti-HIV immune response, as well as nucleic acid molecules and expression vectors encoding those proteins. The AFPs of the invention may comprise domains from various HIV proteins, such as Gag, Pol, Vif, and Env proteins, which are partial sequences. HIVCON is an AFP in which the HIV domains are from several HIV Glade consensus sequences and which optionally contains additional domains which may be useful, for example, in monitoring expression levels or laboratory animal immune responses. Other aspects of the invention may include compositions and methods for inducing an anti-HIV immune response in a subject, preferably with a DNA prime-MVA boost strategy, and to induce a cell-mediated immune response.

Peptide library obtained from multi-clade chimeric immunogens derived from highly conserved regions of the human immunodeficiency virus type 1 (HIV-1) consensus proteome

Disclosed is an immunogen in sterile form suitable for administration to a human subject, the immunogen comprising: at least a portion of the gag protein of HIV, said gag protein being from an HIV clade or having a consensus sequence for one or more HIV clades, and comprising at least parts of p17 and p24; and a synthetic polypeptide comprising a plurality of amino acid sequences, each sequence comprising a human CTL epitope of an HIV protein, and wherein a plurality of HIV proteins are represented in the synthetic polypeptide, said CTL epitopes being selected to stimulate an immune response to one or more HIV clades of interest.

New methods and reagents for vaccination are described which generate a CD8 T cell immune response against malarial and other antigens such as viral and tumor antigens. Novel vaccination regimes are described which employ a priming composition and a boosting composition, the boosting composition comprising a non-replicating or replication-impaired pox virus vector carrying at least one CD8 T cell epitope which is also present in the priming composition.

Methods and reagents for immunization which generate a CD8 T cell immune response

The invention relates to a method of testing a compound for biological activity, which method comprises providing cells expressing one of the CD94/NKG2 family of receptors, contacting the cells with recombinant HLA-E under binding conditions in the presence of the test compound, and determining whether the presence of the compound affects the binding of HLA-E to the cells. The HLA-E property of binding to CD94/NKG2 receptors on NK cells and a subset of CD8+ T cells is useful for targeting CD94/NKG2+ cells for a variety of purposes such as identification, isolation, killing or inactivation.

Plasmodium falciparum MHC class I-restricted CTL epitopes derived from

A novel human immunodeficiency virus type 1 (HIV-1) cytotoxic T-lymphocyte (CTL) epitope has been identified in the gag coding region. This epitope corresponds to amino acids 255-269 of Gag and has the following sequence: NH.sub.2 -asn-pro-pro-ile-pro-val-gly-glu-ile-tyr-lys-arg-trp-ile-ile-COOH. This peptide interacts specifically with human leukocyte antigen-B8 (HLA-B8). This peptide is useful for the identification HIV-1 gag-specific CTL.

HIV-1 gag cytotoxic T-lymphocyte epitope and method of use

Peptides are described which have the amino acid sequence of a fragment of HIV (human immunodeficiency virus) which interacts specifically with a particular human leucocyte antigen (HLA) class I molecule, to stimulate cytotoxic T lymphocyte immunity. Such fragments can be used in a potential vaccine against AIDS (acquired immune deficiency syndrome), and for diagnostic and therapeutic purposes.
