目前认为病毒性肝炎的发病机理不完全为病毒自接引起的肝细胞损害,可能为细胞免疫介导所引起的,即免疫细胞尤其是T淋巴细胞针对已感染的肝细胞膜上所表达的病毒抗原所产生的免疫反应,并在病毒清除方面也起作用。本文对3种肝病46例患者外周血T淋巴细胞亚群进行了检测,并观察了病原学分型与T淋巴细胞亚群之间的关系。 At present, it is thought that the pathogenesis of viral hepatitis is not completely caused by virus self-induced hepatocyte damage, which may be caused by cellular immune mediation, that is, immune cells, especially T lymphocytes, express viral antigens expressed on the infected hepatocyte membrane The resulting immune response also plays a role in virus clearance. In this paper, 46 cases of three kinds of liver disease in patients with peripheral blood T lymphocyte subsets were detected and observed the relationship between etiological types and T lymphocyte subsets.
