Summary: After bariatric surgery, levels of the endogenous bile acid cholic acid-7-sulfate (CA7S) increase in the gastrointestinal tract of both mice and humans. CA7S acts as a G-protein-coupled receptor TGR5 agonist to increase glucose tolerance during insulin resistance. This agonist remains gut-restricted, minimizing off-target effects previously observed for TGR5 agonists absorbed into the circulation.

Summary: This study showed that swainsonine induced liver inflammation in mice by altering bile acid metabolism and gut microbiota. Swainsonine elevated levels of deoxycholic acid (DCA) and taurine-#-muricholic acid (T-#-MCA) due to changes in the gut microbiota composition, leading to suppressed FXR-SHP signaling and increased hepatic Cyp7a1 gene expression. These findings provide new insights into the mechanisms of swainsonine-induced liver inflammation through the gut-liver axis.

Summary: DG treatment suppressed microbes associated with BSH activity, increased taurine-conjugated BAs, and inhibited ileal FXR-FGF15 signaling, leading to improvements in obesity-related metabolism. This demonstrates the potential for a novel approach in the treatment of obesity by targeting gut microbiota-conjugated BAs-FXR axis.

Summary: This article investigates the conformational changes induced by FXR antagonists 2a and 2h using microsecond molecular dynamics simulations. The study reveals that the antagonists can influence the conformations of different FXR regions and cause changes in the heterodimerization interface, thereby affecting the activation and recruitment of coactivators and corepressors.

Summary: This article discusses the role of bile acids and gut microbiota in the pathogenesis of NAFLD. Bile acids act as ligands to several FXRs and their functioning is regulated by gut microbiota, affecting liver fat deposition and fibrosis development.

Summary: Intrahepatic cholestasis of pregnancy (ICP) may increase the susceptibility of offspring to inflammation at an early stage by altering bile acid metabolism and gut microbiota. Supplementation with specific probiotics may improve intestinal immunity in ICP offspring.

Summary: Melatonin (MT) improves hepatic injury and fibrosis in cholestatic liver disease mice by remodeling gut microbiota and activating intestinal farnesoid X receptor (FXR)/fibroblast growth factor 15 (FGF-15) axis-mediated inhibition of hepatic bile acid synthesis and promotion of bile acid excretion.

Summary: It has been reported that aging-induced changes in the gut microbiota may promote hepatic lipid dysmetabolism by shaping the pattern of secondary bile acids. Melatonin treatment reverses these effects and inhibits the expression of hepatic FXR, leading to a decrease in hepatic TMAO production and relief of hepatic lipid dysmetabolism.

Summary: This study revealed the protective role of the FXR-OSGIN1 axis in pancreatitis and identified Osgin1 as a direct target of FXR in the exocrine pancreas. Activation of the FXR-OSGIN1 axis attenuated pancreatitis, while deletion of FXR led to more severe pancreatitis. Mechanistically, the FXR-OSGIN1 axis stimulated autophagic flux to protect against pancreatitis.
