As described, ABX-induced intestinal dysbiosis results in the altered microbial BA metabolism, which destroys the homeostasis between BA synthesis in the liver and BA metabolism in the intestine, restricts the farnesoid X receptor (FXR)/fibroblast growth factor 15 (FGF15) signaling axis in enterocytes with the conjugated BAs being an effective inhibitor of FXR, and further undermines the interplay of FGF15 with fibroblast growth factor receptor 4 (FGFR4) in the hepatocytes (114)
