Protective role of macrophage migration inhibitory factor in nonalcoholic steatohepatitis.

MIF is an inflammatory cytokine but is hepatoprotective in models of hepatotoxin-induced liver fibrosis. Hepatic fibrosis can also develop from metabolic liver disease, such as nonalcoholic fatty liver disease (NASH). We investigated the role of MIF in high-fat or methionine- and choline-deficient diet mouse models of NASH.

Macrophage migration inhibitory factor (MIF) exerts antifibrotic effects in experimental liver fibrosis via CD74.

Macrophage migration inhibitory factor (MIF) is a pleiotropic inflammatory cytokine that has been implicated in various inflammatory diseases. Chronic inflammation is a mainstay of liver fibrosis, a leading cause of morbidity worldwide, but the role of MIF in liver scarring has not yet been elucidated. Here we have uncovered an unexpected antifibrotic role for MIF.
