背景和目的:Fas系统介导的凋亡和以穿孔素为基础的杀伤系统是细胞毒T淋巴细胞(CTL)介导的细胞毒作用的主要途径。免疫组化研究证实,Fas抗原表达与慢性丙肝细胞损伤相关且发现肝内淋巴细胞位于Fas抗原阳性
BACKGROUND & AIM: Fas-mediated apoptosis and perforin-based killing systems are the primary pathways of cytotoxic T lymphocyte (CTL) -mediated cytotoxicity. Immunohistochemical studies confirmed that Fas antigen expression was associated with chronic hepatitis C cell damage and found that intrahepatic lymphocytes were located in Fas antigen positive
