Mice deficient in interferon-γ (IFN-γ) inducible immunity-related GTPase, Irgm1, display defective host resistance to a variety of intracellular pathogens. This increased susceptibility to infection is associated with impaired IFN-γ-dependent macrophage microbicidal activity in vitro. Here, we show that Irgm1 also regulated the survival of mature effector CD4+ T lymphocytes by protecting them from IFN-γ-induced autophagic cell death. Mice deficient in both IFN-γ and Irgm1 were rescued from the lymphocyte depletion and increased mortality that occurs in single Irgm1–/– animals following mycobacterial infection. These studies reveal a feedback mechanism in the TH1 response that limits the detrimental effects of IFN-γ on effector T lymphocyte survival while promoting the anti-microbial functions of IFN-γ.
