Abstract
Primary biliary cholangitis (PBC) is an immune-mediated cholestatic liver disease of unknown pathogenesis. The research on immunologic injury in the past helps us to understand more about this disease, but there are still many problems and challenges in the research on PBC. With a focus on the cholestatic features of PBC, this article reviews the research advances in bile acid metabolism in the field of PBC, in order to provide new thoughts for future research.
