AbstractThe activation of natural killer (NK) cells, cytotoxic lymphocytes capable of major histocompatibility complex (MHC) unrestricted killing and early antiviral defense, is temporally related to the increased interferon (IFN-α/β production that is seen in the viral infection of mice. Type 1 IFN (IFN-α/β) are expressed in many cell types early after primary viral infection and have been shown to mediate resistance against a variety of viruses. In this study, the role of the transcriptional activator IFN regulatory factor-1 (IRF-1) in murine NK cell activity was assessed. IRF-1- deficient mice displayed a normal frequency of NK marker-positive cells, but exhibited greatly reduced NK cell-mediated cytotoxicity after both virus infection and stimulation with the IFN inducer polymosinic:polycytidilic acid in vivo. In vitro, cytolytic activity in IRF-1-deficient NK cells remained defective after stimulation with IFN-β, IL-2, and IL-12 IRF-1 deficient mice were unable to eliminate syngeneic MHC class 1-negative tumor cells in vivo, and had a reduced ability to reject parental semi-allogeneic donor cells from the circulation. Thus, IRF-1 is essential for the induction of NK cell- mediated cytotoxicity and for the in vivo effector functions that are mediated by this activity.
