The bile acid rsodeoxycholic acid (UDCA) is the choice of treatment for primary biliary cholangitis patients with abnormal liver enzymes; however, its mechanism is not clear, and is the focus of this investigation. Bile acids alter mast cell (MC) histamine release. Following liver injury, such as that seen in primary sclerosing cholangitis, MCs infiltrate the liver. MC-derived histamine increases biliary damage, fibrosis, and inflammation. UDCA treatment decreases these parameters via reduced MC activation.
