巨噬细胞在原发性胆汁性胆管炎发生发展中的作用

Role of macrophages in the development and progression of primary biliary cholangitis

原发性胆汁性胆管炎(PBC)是一种持续的炎症性自身免疫性肝病,以肝内小胆管炎症损伤和胆汁淤积为主要特征。目前,PBC的确切发病机制尚不清楚,但一致认为PBC是多种因素协同作用的结果。而在与PBC相关的免疫和炎症级联反应中,巨噬细胞作为必不可少的免疫细胞出现,积极参与对胆管上皮细胞的损伤。本文介绍了巨噬细胞在PBC中的来源定位及异质性变化,综述了巨噬细胞在PBC发病机制中的潜在作用。

Primary biliary cholangitis(PBC)is a persistent inflammatory autoimmune liver disease characterized by inflammatory injury and cholestasis in the small intrahepatic bile ducts.At present,the exact pathogenesis of PBC remains unknown,but a consensus has been reached on the fact that PBC is the result of the synergistic effect of various factors.In the cascade of immune and inflammatory reactions associated with PBC,macrophages appear as essential immune cells and actively participate in the damage to bile duct epithelial cells.This article introduces the origin and heterogeneity of macrophages in PBC and reviews the potential role of macrophages in the pathogenesis of PBC.
