2、组外周血中CIMT细胞上的PD一1/PD—L1的表达频率。结果54例CHB患者的PD一1与PD—L1的表达水平分别为0.96%±0.29%和0.49%±0.18%,显著高于健康对照组(t分别为7.89和6.57,P<0.O1),HBeAg阳性组患者外周血T细胞中PD—l的表达频率显著高于阴性组(1.04%±0.29%vs0.88%±0.25%,t=2.85,P<0.01)。HBeAg阳性组患者PD—L1百分率显著高于阴性组(0.51%±0.12%vs0.43%±0.12%,t=2.26,P<0.05)。病毒载量与PD一1和PD—L1的表达水平呈显著正相关(r分别为
3、0.393和0.271,P<0.叭),与ALT、TB1L、PT无相关性。结论慢性乙型肝炎患者淋巴细胞上B7一HI和PD一1的表达水平与患者疾病状态密切相关,可能是慢性乙型肝炎患者治疗的潜在靶点。关键词:慢性乙型肝炎;程序性死亡受体一1;共刺激分子中图分类号:R512.62文献标识码:A文章编号:1004—8685(2014)12—1754—03Expressioncharacteristics0fprogrammedcelldeath一1inchr0IlichepatitisBpatientsLIUHong—mei.XUWen—fangDepartmentofCl
