IFN-γ is an important mediator of immunity and inflammation that utilizes the Jak-STAT pathway to activate STAT1. Many functions of IFN-γ have been ascribed to direct STAT1-mediated induction of immune effector genes, but recently it has become clear that key IFN-γ functions are mediated by crossregulation of cellular responses to other cytokines and inflammatory factors. Here we review mechanisms by which IFN-γ and STAT1 regulate signaling by TLRs, inflammatory factors, tissue destructive cytokines, anti-inflammatory cytokines, and cytokines that activate opposing STATs. These signaling mechanisms reveal insights about how IFN-γ regulates macrophage activation, inflammation, tissue remodeling, and Th and Treg differentiation, and how Th1 and Th17 responses are integrated in autoimmune diseases.
