为了研究CD4+CD25+调节性T细胞和CD8+CD28−抑制性T细胞的状况,检测了与间质性肺炎(IP)相关的风湿性疾病患者T细胞上CD25或CD28的表达。55例各种风湿性疾病患者和23例正常对照。IP患者的CD4+CD25+ T细胞显著低于非IP患者,IP患者的CD8+CD28− T细胞比例显著高于非IP患者或正常对照。CD8+CD28− T细胞的这些结果与CD8+CD28+ T细胞的减少雅阁,并且可能与活化诱导的CD8+CD28+ T细胞死亡有关。因此,CD4+CD25+调节性T细胞的异常可能与IP的发病机制以及CD8+ T细胞的存活和活化有关。
The expression of CD25 or CD28 on T cells was examined in patients with rheumatic diseases associated with interstitial pneumonitis (IP), in order to investigate the conditions of CD4+CD25+ regulatory T cells and CD8+CD28− suppressor T cells. Fifty-five patients with various rheumatic diseases and 23 normal controls were enrolled. CD4+CD25+ T cells of patients with IP were significantly decreased in comparison with non-IP patients, and the ratio of CD8+CD28− T cells in patients with IP was significantly higher than that in non-IP patients or normal controls. These results for CD8+CD28− T cells were in accord with the decrease in CD8+CD28+ T cells, and may be related to activation-induced CD8+CD28+ T-cell death. Thus, the abnormality of CD4+CD25+ regulatory T cells may be related to the pathogenesis of IP, and the survival and activation of CD8+ T cells.
