IL17A and metabolic dysfunction-associated steatotic liver disease: Studies have found that in NAFLD models induced by a high-fat diet (HFD) and high-fat and high-cholesterol diet (hfhcd), γδT cells, especially γδT17 cells produced by IL-17A, are significantly enriched in the liver, and aggravate liver inflammation and injury by recruiting granulocytes and inducing reactive oxygen species [182].
