Abstract
Primary biliary cholangitis (PBC) is an autoimmune liver disease, mainly characterized by chronic progressive cholestasis. The root cause of PBC is the loss of immune tolerance to autoantigen E2 subunit of pyruvate dehydrogenase (PDC-E2). The unique immunobiological characteristics of intrahepatic bile duct epithelial cells make it an active participant in the pathogenesis of PBC. In recent years, the detection rate of PBC has been increasing year by year, but the clinical situation of ursodeoxycholic acid monotherapy has not changed. Therefore, an in-depth understanding of the immune pathogenesis of PBC will help clinicians better prevent and treat diseases.
Key words:
