IFN-纬 induces expression of immunity-related GTPases (IRG) in Leishmania donovani infection in the liver.
In liver, both Irgm1 and Irgm3 promote early intracellular resistance and granuloma assembly.
Irgm3, but not Irgm1, optimizes macrophage parasite killing induced by antimony chemotherapy.
IFN-纬-induced IRGs exert regulatory antileishmanial effects.
