摘要 目的探讨外周血CD4+ T细胞中CD25表达率和CD8+ T细胞中CD28表达率在HIV/AIDS患者发病中的作用。方法应用流式细胞仪荧光染色技术检测35例HIV/AIDS患者CD4+ T细胞中CD25表达和CD8+ T细胞中CD28的表达,以41名健康体检人员做对照。结果HIV/AIDS患者和健康对照组之间CD4+ T细胞中CD25表达率(27.51±4.23)%,(44.41±9.17)%,CD4+25+ T细胞占淋巴细胞的比例(2.00±1.42)%,(16.62±4.60)%,CD4+25- T细胞占淋巴细胞的比例(5.16±3.37)%,(21.03±6.19)%,CD8+ T细胞中CD28中的表达率(25.12±6.33)%,(44.24±8.61)%,CD8+28- T细胞占淋巴细胞的比例(36.85±8.98)%,(13.33±4.58)%的差异均有显著性(P<0.01),CD8+ 28+ T细胞占淋巴细胞的比例(12.31±4.14)%,(10.51±3.71)%差异无显著性(P>0.05)。结论HIV/AIDS患者CD25在CD4+ T细胞与CD28在CD8+ T细胞的表达率降低可能与HIV感染后引起的免疫缺陷有关,CD8+ CD28- T细胞的增加有助于促进HIV/AIDS患者的炎性反应和免疫激活。 Objective To study the expressions of CD25 in CD4^ + T cells and CD28 in CD8^+ T cells in the peripheral blood of HIV/AIDS. Methods CD25 in CD4^ + T cells and CD28 in CD8^+ T cells in the peripheral blood of 35 HIV/AIDS and 41 normal eontrol were detected by flow eytonetr. Results It shows that in patients with HIV/AIDS and the normal subjects,the expression percent of CD25 in CD4 ^+T cells [ (27.51 ± 4.23 )%, (44.41 ±9. 17)% ],CD4^ +25^ + T cells[ (2. 00 ± 1.42)%, (16.62 ±4.60) % ] ,CD4^ +25^ - T eells[ (5.16 ± 3.37 ) %, (21.03 ± 6.19 ) % ] ,CD28 in CD8^+ T cells [ ( 25.12 ± 6.33 ) %, (44.24 ± 8.61 ) % ], CD8 ^+ 28 - T eells[ (36.85 ± 8.98) %, ( 13.33 ± 4.58 ) % ] had significantly different ( P 〈 0.01 ) ; CD8 ^+ 28 ^+ T cells[ ( 12.31 ± 4.14 ) %, ( 10.51 ± 3.71 ) % ] had no significantly different ( P 〉 0.05 ). Conclusions The low expression of CD25 in CD4^ + T cells and CD28 in CD8 ^+ T cells in HIV infection patients was elosely associated with Innunodefieieney by HIV infeetion, the inerease of CD8^+ 28^ - T cells help to promote HIV/ AIDS patients with inflammatory response and immune activation.
