This retrospective study was designed to assess statin effects on T-cell activation from HIV-infected individuals. Peripheral blood mononuclear cells from antiretroviral therapy suppressed HIV-infected individuals receiving atorvastatin or pravastatin were evaluated for T-cell activation, exhaustion and function. Atorvastatin was associated with a significant reduction in CD8 T-cell activation (HLA-DR, CD38/HLA-DR) and exhaustion (TIM-3, TIM-3/PD-1) whereas pravastatin had no effect. In contrast, pravastatin increased antigen specific interferon γ production. These results suggest a differential effect of statins on immune activation and function.
这项回顾性研究旨在评估他汀类药物对HIV感染者T细胞激活的影响。对接受抗逆转录病毒治疗的HIV感染者服用阿托伐他汀或普伐他汀后外周血单个核细胞的T细胞激活、耗竭及功能进行了评估。阿托伐他汀与CD8 T细胞激活(HLA-DR、CD38/HLA-DR)及耗竭(TIM-3、TIM-3/PD-1)的显著降低相关,而普伐他汀则无此作用。相反,普伐他汀增加了抗原特异性干扰素γ的产生。这些结果表明他汀类药物对免疫激活和功能有不同的作用。
