Mucosal-associated invariant T cells are a profibrogenic immune cell population in the liver

Hepatic fibrosis represents the liver response to chronic injury and can lead to cirrhosis. Here the authors show that mucosal-associated invariant T cells mediate chronic inflammation and fibrogenesis in the liver by inducing a proinflammatory phenotype in macrophages and myofibroblasts and proliferation of the latter.
