Bile acid regulation

"Bile acid regulation" is not the name of a specific molecule or receptor, but rather refers to the complex physiological processes and molecular pathways that control the synthesis, transport, signaling, and homeostasis of bile acids in the body. Bile acids themselves are amphiphilic molecules derived from cholesterol in hepatocytes and play key roles in lipid digestion, cholesterol elimination, metabolic regulation (including glucose and energy metabolism), immune modulation, and gut microbiome composition[2][3][4]. The regulation of bile acids involves multiple enzymes (such as CYP7A1), transporters (like BSEP/ABCB11, NTCP), nuclear receptors (notably farnesoid X receptor [FXR]), G protein-coupled receptors (such as TGR5), and other signaling molecules[1][3][4]. Because "bile acid regulation" does not refer to a single targetable entity but rather an entire regulatory network or pathway involving many distinct proteins and receptors—several of which are considered therapeutic targets—the entry is too broad for structured target annotation.
