【摘要】 目的:探讨HCV感染者外周血中CD4+CD25+调节性T细胞的表达状况以及与疾病进程的相关性。方法:选取HCV感染者69例及健康对照23例,应用流式细胞术检测外周血中CD4+CD25+调节性T细胞的表达。结果:HCV感染组外周血中CD4+CD25+调节性T细胞占CD4+T细胞比例明显高于对照组(P<0.01);慢性感染组外周血CD4+CD25+调节性T细胞比例高于HCV无症状携带组(P<0.05);肝硬化组外周血CD4+CD25+调节性T细胞比例高于慢性感染组(P<0.05)。结论:HCV感染者外周血CD4+CD25+调节性T细胞水平与疾病进程具有相关性。更多还原

【Abstract】 Objective:To investigate the expression of peripheral blood CD4+CD25+ regulatory T cells in patients with hepatitis C and its relationship with progression of disease.Methods:Technique of flow cytometry was used to detect peripheral blood CD4+CD25+ regulatory T cells of 69 patients with Hepatitis C and 23 controls.Results:The percentage of CD4+CD25+ regulatory T cells was significantly higher in patients with hepatitis C than those in healthy controls(P<0.01).The chronic hepatitis C group had a higher percentage of CD4+CD25+ regulatory T cells than that of asymptomatic carrier(P<0.05)and the group of patients with liver cirrhosis had a higher percentage of CD4+CD25+ regulatory T cells than that of chronic hepatitis C group(P<0.05).Conclusion:Peripheral blood CD4+CD25+ regulatory T cells levels are correlated with the progression of HCV infection.更多还原
