Microbial metabolites in non-alcoholic fatty liver disease

World J Gastroenterol. 2019 May 7;25(17):2019-2028. doi: 10.3748/wjg.v25.i17.2019.

Abstract

The prevalence of non-alcoholic fatty liver disease (NAFLD) is rising exponentially worldwide. The spectrum of NAFLD includes non-alcoholic fatty liver, non-alcoholic steatohepatitis, liver cirrhosis, and even hepatocellular carcinoma. Evidence shows that microbial metabolites play pivotal roles in the onset and progression of NAFLD. In this review, we discuss how microbe-derived metabolites, such as short-chain fatty acids, endogenous ethanol, bile acids and so forth, contribute to the pathogenesis of NAFLD.

Keywords: Microbial metabolites; Non-alcoholic steatohepatitis; Short-chain fatty acids.
