ABSTRACT
In view of the importance of cell-associated virus in AIDS virus transmission, an HIV vaccine should be able to induce a virus-specific CTL response. Traditional subunit vaccines have not elicited virus-specific CD8+ MHC class I-restricted CTL. We have used the simian immunodeficiency virus of macaques (SIVmac)/rhesus monkey model to explore the use of CTL epitope peptide-helper peptide conjugates for the vaccine elicitation of AIDS virus-specific CTL. We found that both the CTL epitope peptide-helper peptide conjugate and the CTL epitope peptide alone, when delivered in an emulsion with IFA, induced CTL epitope-specific CD8+ MHC class I-restricted CTL. These effector cells recognized processed viral protein and were readily cloned from PBL of the immunized monkeys. Moreover, the cloned effector cells inhibited SIVmac replication in PBL. Immunization with the CTL epitope peptide used in this study also elicited a CD4+ PBL proliferative response, suggesting that the peptide also contained a helper epitope. These studies provide further evidence for the potential usefulness of peptide-based AIDS virus vaccines.
