Résumé des résultats (Abstract) (Anglais)

Specific stimulation of MHC class I-restricted cytotoxic T lymphocytes (CTL) responses is a key objective for vaccines against intracellular infections. Epitope repertoires (ER) recognized by CTL are generated by processing antigen in protea some/TAP-dependent (ER^prot) and alternative proteasome/TAP-independent (ER^alt) pathways. Many new vaccination strategies prime CTL to alternatively pro-cessed antigens. The consortium targets the analysis of alternative processing of vaccine-relevant anti-gens from HCV, HBV and malaria plasmodia resulting in peptides for human/murine MHC class I pre-sentation. It will be tested if CTL populations specific for the ER^alt alone, or in combination with CTL recognizing the ER^prot are associated with protection against natural human HBV, HCV and plasmo-dium infections. The insight into alternative processing will be used to design and test optimised safe vaccines that induce broad CTL immunity also to the ER^alt.
