The transcription factor interferon regulatory factor 1 (IRF-1) binds tightly to the interferon (IFN)-beta promoter and has been implicated in the induction of type I IFNs. We generated mice devoid of functional IRF-1 by targeted gene disruption. As reported by others, IRF-1-deficient mice showed a discrete phenotype: the CD4/CD8 ratio was increased and IFN-gamma-induced levels of macrophage iNO synthase mRNA were strongly diminished. However, type I IFN induction in vivo by virus or double-stra ...[more]
