摘要Non-alcoholic fatty liver disease(NAFLD)has become the most common cause of chronic liver disease worldwide,and is closely associated with the increased risk of the prevalence of obesity and diabetes.NAFLD begins with the presence of＞5％excessive lipid accumulation in the liver,and potentially de-velops into non-alcoholic steatohepatitis,fibrosis,cirrhosis and hepatocellular carcinoma.Therefore,insight into the pathogenesis of NAFLD is of key importance to its effective treatment.Iron is an essential element in the life of all mammalian organisms.However,the free iron deposition is positively associated with histological severity in NAFLD patients due to the production of reactive oxygen species via the Fenton reaction.Recently,several iron metabolism-targeted therapies,such as phlebotomy,iron chela-tors,nanotherapeutics.and ferroptosis,have shown their potential as a therapeutic option in the treatment of NAFLD and as a clinical strategy to intervene in the progression of NAFLD.Herein,we review the recent overall evidence on iron metabolism and provide the mechanism of hepatic iron overload-induced liver pathologies and the recent advances in iron metabolism-targeted therapeutics in the treatment of NAFLD.
