PBMC cultured overnight in IL-2 exhibit enhanced cytolytic ability against HIV-infected CD4 T-cell targets.

Autologous HIV-infected (▧) and uninfected (░) CD4 T-cell blasts were used as targets. Effector cells were thawed PBMC (A) or were cultured overnight in the absence (B) or presence (C) of IL-2 and were tested at an E:T ratio of 100:1.
