In this study we demonstrate the anti-apoptotic effect of IL-12 and its underlying mechanism in CD8 T cells. The prolonged stimulation of CD8 T cells with anti-CD3 alone caused apoptosis mediated by Fas and the caspase signaling pathway. However, costimulation with IL-12 significantly prevented anti-CD3-induced apoptosis of CD8 T cells. IL-12 decreased the number of Fas ligand-positive CD8 T cells and inhibited the activation of caspase-8 and caspase-3. In addition, IL-12 up-regulated cellular FLIPs but not Bcl-2 family proteins or cellular inhibitor of apoptosis proteins. These data suggest that IL-12 provides survival signals to CD8 T cells by down-regulating Fas ligand and up-regulating cellular FLIPs, followed by inhibiting caspase activation, which implies a role for IL-12 in peripheral responses of CD8 T cells in vivo.
