In view of the growing evidence that virus-specific cytotoxic T lymphocytes
(CTL) play an important role in containing the early spread of human
immunodeficiency virus type 1 (HIV-1) in infected individuals, novel
vaccine strategies capable of eliciting HIV-1-specific CTL are being
pursued in attempts to create an effective AIDS vaccine. We have used the
simian immunodeficiency virus of macaques (SIVmac)/rhesus monkey model to
explore the induction of AIDS virus-specific CTL responses by DNA
vaccination. We found that the inoculation of rhesus monkeys with plasmid
DNA encoding SIVmac Env and Gag elicited a persisting SIVmac-specific
memory CTL response. These CTL were CD8+ and major histocompatibility
complex class I restricted. These studies provide evidence for the
potential utility of DNA inoculation as an approach to an HIV-1 vaccine.
