摘要
目的 探讨外周血T细胞抗原受体γδT细胞Vδ1与Vδ2亚群在HIV/AIDS疾病中的变化情况。方法 采用流式细胞术对55例HIV/AIDS患者、20例结核病患者以及21例正常健康对照的γδT细胞及其亚群Vδ1与Vδ2细胞的数量进行检测。结果 研究结果显示HIV/AIDS组的外周血TCR γδT细胞的百分率分别较正常对照组明显增高(P〈0.01);与正常组比较,HIV感染组、AIDS患者合并结核病以及肺结核患者组外周血γδT细胞中Vδ1亚群细胞均显著增多(P〈0.001),而Vδ2亚群细胞均显著减少(P〈0.001),均出现Vδ1亚群细胞与啦亚群细胞比例倒置的关系;同时以AIDS患者合并结核病组的γδT细胞亚群变化幅度最大,该组Vδ1细胞与Vδ2细胞分别明显高于(P〈0.001)和低于(P〈0.001)HIV感染组和单纯肺结核组。结论 机体在HIV-1或结核菌感染后,其外周血γδT细胞及其亚群的数量发生明显变化,且出现Vδ1/Vδ2细胞比值倒置,在合并结核病时其变化加剧。造成这种改变的机理有待进一步研究。
Objectlve To evaluate the profile of the γδT cell populations in patients with HIV-1 infection. Methods The study was performed in 55 cases ofHIV/AIDSpafients, The count of γδT cell. Vδ1 and Vδ2 T cell were analysed by Flow cytometry with 21 cases of blood donors and 20 cases of TB patients acted as controls. Results Abnormal expansion of γδT cell in HIV- 1 infected patients( P 〈 0.01 ) ; and HIV- 1 infection is associated with significant expansion of Vδ1 (P 〈 0.1301 ) was shown contraction of Vδ2( P 〈 0.1301 ) γδT cell populations in the peripheral blood, and inversion of Vδ1 to Vδ2 ratio was shown. In the meanwhile the γδT cell populations in HIV-TB coinfeefion group have changed significantly( P 〈 0.001) compared with HIV or TB infection group. Conclution HIV-1 infection and HIV-1/TB coinfection are associated with significant changes of the peripheral blood γδT cell populations. The factors driving these changes remain unknown.
