Primary bile acids, such as cholic and chenodeoxycholic acids, are synthesized from cholesterol in the liver, conjugated to either taurine or glycine, and then excreted through the canaliculi to the biliary system. 28,29 Following their excretion to the gastrointestinal tract, a portion of bile acids will be deconjugated and modified by bacterial metabolism, including oxidation, esterification ...

Bile acids, amphipathic end products of cholesterol metabolism, are “good” in the infant because they enhance lipid absorption and thereby promote growth. Bile acids also induce bile flow and biliary lipid secretion. The enterohepatic circulation of bile acids is “bad” in the adult because it downregulates hepatocyte low-density lipoprotein receptor activity and thereby elevates plasma ...

Identifying risk factors is a crucial challenge in directing experimental research, particularly when searching for environmental factors. Familial history and genetic predisposition are by far the most convincing risk factors identified for PBC. However, several non-genetic factors have also been proposed to play a part.

Human bile acids (BAs) are C24 molecules comprised of a C19 cyclopentanophenanthrene (steroid) nucleus and a carboxylate side chain. They are cholesterol metabolites undergoing extensive enterohepatic circulation driven by a series of host-gut microbial metabolism and transport mechanisms [1,2,3].During exchanges between the host and gut microbiota, BAs act on both of them and play multiple ...
