Autocrine IFN-γ signaling is important for CD4 differentiation to T helper 1 effector cells, but it has been unclear whether it contributes to CD8 T cell differentiation. We show here that naïve murine CD8 T cells rapidly and transiently produce low levels of IFN-γ upon stimulation with Ag and B7-1, with production peaking at about 8 hours and declining by 24 hours. The autocrine IFN-γ signals for upregulation of expression of Tbet and GrzB, and induces weak cytolytic activity and effector IFN-γ production. IFN-α acts synergistically with IFN-γ to support development of strong effector functions, while IL-12 induces high T-bet expression and strong function in the absence of IFN-γ signaling. Thus, IFN-γ is not only an important CD8 T cell effector cytokine, it is an autocrine/paracrine factor whose contributions to differentiation vary depending on whether the response is supported by IL-12 or Type I IFN.
