Lipopeptide inducing T-cytotoxic lymphocytes and their use as vaccines

摘要

The use of a lipopeptide (I) is claimed for the immunization of humans or animals against pathogens or tumor cells, where (I) contains: (i) a peptide component having 10-40 (preferably 10-20) amino acids; (ii) at least one antigenic determinant which specifically induces cytotoxic T-lymphocytes; and (iii) one or more chains derived from N- epsilon -palmitoyl-L-lysine, coupled to the carboxy functions of the aminoacids. An Independent claim is included for a lipopeptide (I') for immunization against HIV-1 or HIV-2, comprising (I) as above in which component (i) is a fragment of an HIV-1 or HIV-2 protein.
