Stimulation of secondary nef-specific CTLs by UbMNef and UbRNef constructs. PBMCs were isolated from an HIV-1 seropositive donor and stimulated in the presence of IL-2 with titrating numbers of vVUbMNef (squares) or vVUbRNef (diamonds) infected, psoralen/UV–treated autologous B-LCL. Stimulated PBMCs were assayed for nef-specific CTL activity against vVnef infected (filled) or vac control infected (open) autologous B-LCL at an E/T ratio of 10.
