| Abstract: | PBL from chimpanzees immunized with a recombinant vaccinia virus that expresses HIV envelope glycoproteins ("env"), were found to proliferate after stimulation with HIV or with "env". Furthermore, CTL clones lytic for autologous target cells expressing HIV envelope glycoproteins were generated after stimulation of the chimpanzees' PBL with "env", indicating that immunization of these primates with a recombinant vaccinia virus primes HIV-specific CTL and also that HIV envelope glycoproteins serve as target antigens for CTL. |
