2、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。【关键词】丙型肝炎病毒;CD4+CD25+调节性T细胞;疾病进程7 AbstractObjective:To investigate the expression of peripheral blood CD4+CD25+ regulatory T cells in patients with hepatitis C and its relationship with progression of disease.M
3、ethods: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 healt
4、hy 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 chron
5、ic hepatitis C group(P<0.05).Conclusion:Peripheral blood CD4+CD25+ regulatory T cells levels are correlated with the progression of HCV infection. Key wordsHCV;CD4+CD25+ regulatory T cells;disease progression7 丙型肝炎呈世界性分布,全球约有超过1.7亿人感染丙型肝炎病毒(HCV),且70%~90%形成慢性感染[1],30%发展为进
