Abstract: This invention uses our knowledge of the mechanisms by which antigen is recognized by T cells to identify and prepare Plasmodium falciparum epitopes, and to develop epitope-based vaccines directed towards malaria. More specifically, this application communicates our discovery of pharmaceutical compositions and methods of use in the prevention and treatment of malaria. In particular, this application discloses isolated peptides comprising oligopeptides, for example the oligopeptides LLACAGLAY, FLIFFDLFLV, FMKAVCVEV, VLAGLLGNV, GLIMVLSFL, KILSVFFLA, GLLGNVSTV, VLLGGVGLVL, ILSVSSFLFV, QTNFKSLLR, LACAGLAYK, ALFFIIFNK, LLACAGLAYK, HVLSHNSYEK, FILVNLLIFH, FQDEENIGIY, PSDGKCNLY, YYIPHQSSL, FYFILVNLL, KYLVIVFLI and KYKLATSVL, or isolated peptides conjugated with T helper peptides that are used as antigens in epitope-based vaccines to prevent and/or treat malaria.

Abstract: The present invention provides the means and methods for selecting immunogenic peptides and the immunogenic peptide compositions capable of specifically binding glycoproteins encoded by HLA alleles and inducing T cell activation in T cells restricted by the allele. One such peptide, NMLSTVLGV (SEQ ID NO: 183) is useful to elicit an immune response against influenza. The present invention also provides a heteropolymer of an isolated immunogenic peptide less than 15 amino acids in length comprising the oligopeptide NMLSTVLGV (SEQ ID NO: 183) and at least one different peptide.
