This narrative review examines how bacterial metabolites, particularly ammonia and bile acids (BAs), contribute to hepatic encephalopathy (HE) by summarizing evidence from human clinical observations and preclinical animal models. The central conclusion is that dysregulated BAs and their receptors (FXR, TGR5, S1PR2) are important mechanistic players in HE pathology alongside ammonia.
This narrative review synthesizes literature on the role of bacterial metabolites, specifically ammonia and bile acids (BAs), and BA receptors in hepatic encephalopathy (HE). Central results indicate that elevated BAs can disrupt the blood-brain barrier, promote neuroinflammation via receptors like S1PR2, and that modulation of BA signaling (e.g., FXR knockdown) can alter neurological outcomes in animal models.
