糖皮质激素对多发性硬化患者外周血淋巴细胞CD80和CD4^+CD25^+T细胞表达的影响

Effects of glucocorticoid on the expression of CD80 and CD4^+CD25^+T cells in peripheral blood lymphocyte of patients with multiple sclerosis

目的探讨糖皮质激素(GC)对多发性硬化(MS)患者外周血淋巴细胞CD80和CD4+CD25+T细胞表达的影响。方法利用流式细胞仪检测21例MS急性期患者GC治疗前后外周血淋巴细胞CD80和CD4+CD25+T细胞阳性率,并与正常对照组比较;比较MS患者治疗前后扩展功能障碍状况量表(EDSS)评分的变化。结果MS患者急性期外周血淋巴细胞CD80的阳性率[(5.031±1.782)%]较正常对照组[(6.436±2.035)%]明显下降(P<0.05),经GC治疗后CD80的阳性率[(6.467±1.882)%]明显增高(P<0.01);CD4+CD25+T细胞阳性率治疗前后与正常对照组间差异均无统计学意义;治疗后EDSS评分[(3.64±1.79)分]较治疗前[(4.26±1.68)分]明显下降(P<0.01)。结论GC可上调MS患者淋巴细胞CD80的表达,抑制细胞免疫,促进MS病情缓解。

Objective To investigate the effects of glucocorticoid(GC) on the expression of CD80 and CD4+CD25+T cells in peripheral blood lymphocyte of patients with multiple sclerosis (MS). Methods With flow cytometer,the positive rates of CD80 and CD4+CD25+T cells in peripheral blood lymphocyte were detected in 21 acute MS patients pre and post treatment separately,and compared with the nomal control group.The secols of Expanded Disablility Status Scale(EDSS) were compared pre and post treatment in MS patients.Result...
