[Pathogenesis of immunoglobulin G4-related hepatobiliary disease].

IgG4-relaed hepatobiliary diseases (IgG4-HBD) are the hepatobiliary manifestations of IgG4-related disease, a multisystem fibro-inflammatory disorder. Previous studies on the pathogenesis of genetics and immunology have provided significant assistance in understanding the disease, rational diagnosis and treatment, but there are still many unknowns and challenges. The current research progress summarizes several factors influencing fibrosis and inflammation in the pathogenesis of disease.
