| 内容記述 | Primary biliary cirrhosis (PBC) is histologically characterized by chronic nonsuppurative destructive cholangitis (CNSDC) and the progressive loss of intrahepatic small bile ducts. Cellular immune mechanisms involving T-cell reaction are thought to be significantly involved in the formation of CNSDC and bile duct loss. In inflamed portal tracts of PBC, CD4+ T cells of Th1 type expressing IFN-γ or CXCR3 are aggregated and more commonly detected around injured bile ducts than Th2-type CD4+ T cells expressing IL-4 or CCR4, indicating that Th1-dominant cellular immunity plays a more-prominent role in recruitment of memory T-cell subsets in PBC and may be responsible for the progressive bile duct damage. Biliary epithelial apoptosis is demonstrated to be a major pathogenic process of bile duct loss in PBC. In CNSDC, several biliary apoptotic cells, an aberrant expression of Fas antigen (proapoptotic molecule) and decreased expression of bcl-2 and mcl-1 (antiapoptotic molecules) are found, although interlobular bile ducts express bcl-2 and mcl-2 but lack Fas. In addition, the upregulation of WAF1 and p53 related to biliary apoptosis is found in biliary epithelial cells of PBC, which may be due to cell senescence in response to genotoxic damage such as oxidative stress. Several steps and mechanisms during induction and progression of cholangitis and biliary apoptosis followed by bile duct loss are now being proposed in PBC, but future analysis of an etiopathogenesis to explain the characteristic histopathogenesis of PBC is required. © 2006 The Japanese Society for Clinical Molecular Morphology. | |||||
