抗病毒治疗后HIV 感染者NKT 样细胞衰老和体外增殖研究

目的:研究高效抗逆转录病毒治疗(Highly active antiretroviral therapy,HAART)后NKT 样细胞衰老和体外增殖情况。方法:选取未接受HAART 治疗、接受HAART 治疗的HIV 感染者以及健康人的外周血细胞,利用流式细胞仪检测接受HAARRT 治疗前后的HIV 感染者NKT 样细胞CD57 的表达情况以及体外增殖能力。结果:HIV 感染者在HAART 治疗前NKT 样细胞的百分数显著低于健康对照组(P<0.01),HAART 治疗后恢复(P<0.05);HAART 治疗前NKT 样细胞CD57 的表达明显高于健康对照组(P<0.01),HAART 治疗后恢复(P<0.05);HAART 治疗前NKT 样细胞体外增殖能力明显低于健康对照组,HAART 治疗后有所恢复。结论:经过HAART 治疗后,HIV 感染者NKT 样细胞的数量、CD57 表达以及体外增殖能力有所恢复。

Study on senescence and proliferation of NKT like cells in HIV infected patients after antiviral therapy

Objective: To better understand the changes of the NKT like cells after HIV infection and HAART Treatment.Methods: Peripheral blood from HIV-infected individuals, HAART-treatment AIDS patients and healthy controls were collected, the expression of CD57 and the proliferation ability of NKT like cells before and after HAART were analyzed by flow Cytometry.Results: We found that the percentage of NKT like cells before HAART was significantly lower than the healthy controls (P<0.01),and recovered after HAART treatment(P <0.05);the aging of NKT like cells was significantly higher before HAART compared with health individuals (P<0.01),and recovered after HAART treatment(P<0.05)the proliferation was significantly lower in vitro before HAART compared with healthy controls,and partial recovered after HAART.Conclusion: After HAART treatment,the number of NKT like cells,CD57 expression and the proliferation ability of HIV infected patients were restored.
