人类免疫缺陷病毒 (HIV) 感染会破坏 γδ T 细胞亚群之间的平衡,导致 Vδ1+ 细胞增加,而循环 Vδ2+ 细胞大量减少。耗竭是 HIV 对 CD4 阴性 Vδ2 细胞的间接影响,但对 Vγ2-Jγ1 识别的磷酸抗原反应亚群具有特异性。 2(也称为 Vγ9-JγP)T 细胞受体重排。细胞损失和恢复的程度与临床状态密切相关,病毒控制者中存在最高水平的功能性Vδ2细胞(在没有抗逆转录病毒治疗的情况下检测不到病毒血症)。我们回顾了 HIV 疾病中 Vδ2 细胞耗竭的机制和临床后果。我们解决的问题是,尽管 HIV 介导的 Vδ2 细胞耗竭是感染的间接影响,但它是否是该病毒免疫逃避策略的重要组成部分。 Vδ2 细胞作为效应器和免疫调节器的重要作用,确定了受 HIV 影响的关键机制,并显示了 Vδ2 细胞损失与免疫缺陷疾病之间的密切关系。该领域正在朝着基于靶向 Vδ2 细胞的免疫疗法发展,我们现在有明确的目标和期望来指导介入临床试验。
Infection with human immunodeficiency virus (HIV) disrupts the balance among γδ T cell subsets, with increasing Vδ1+ cells and substantial depletion of circulating Vδ2+ cells. Depletion is an indirect effect of HIV in CD4-negative Vδ2 cells, but is specific for phosphoantigen-responsive subpopulations identified by the Vγ2-Jγ1. 2 (also called Vγ9-JγP) T cell receptor rearrangement. The extent of cell loss and recovery is related closely to clinical status, with highest levels of functional Vδ2 cells present in virus controllers (undetectable viremia in the absence of antiretroviral therapy). We review the mechanisms and clinical consequences for Vδ2 cell depletion in HIV disease. We address the question of whether HIV-mediated Vδ2 cell depletion, despite being an indirect effect of infection, is an important part of the immune evasion strategy for this virus. The important roles for Vδ2 cells, as effectors and immune regulators, identify key mechanisms affected by HIV and show the strong relationships between Vδ2 cell loss and immunodeficiency disease. This field is moving toward immune therapies based on targeting Vδ2 cells and we now have clear goals and expectations to guide interventional clinical trials.
