The invention relates to the identification and the selection of CTL epitopes
able to induce a protection against an HIV infection. More particularly, the invention
is concerned with peptides and nucleic acid sequence coding for these peptides
derived from HIV-1 proteins such as GAG, POL, ENV, VIF, TAT, VPU, REV and their
applications. Preferably the immunogenic peptides are selected from the group consisting
of SEQ ID NOs:1 to 18 and functional derivatives thereof. The invention also relates
to antibodies directed against said peptides.
