已经在小鼠和人中观察到慢性病毒感染期间T细胞应答的耗竭,并且已经归因于耗竭的T细胞表面上的PD-1的上调。在慢性人类HIV感染患者中,T细胞耗竭导致与AIDS相关的机会性感染。然而,并非所有耗尽的T细胞都表达PD-1,这表明其他分子可能参与了表型。一项新的研究现在证明了T细胞免疫球蛋白和含粘蛋白结构域的蛋白-3(TIM-3)在慢性HIV感染期间T细胞耗竭中的核心作用,并表明TIM-3可能是慢性病毒性疾病的新治疗靶点。
Exhaustion of T cell responses during chronic viral infections has been observed in both mouse and man and has been attributed to up-regulation of PD-1 on the surface of exhausted T cells. In patients with chronic human HIV infection, T cell exhaustion leads to opportunistic infections associated with AIDS. However, not all the exhausted T cells express PD-1, suggesting that other molecules may be involved in the phenotype. A new study now demonstrates a central role for T cell immunoglobulin and mucin domain–containing protein-3 (TIM-3) in T cell exhaustion during chronic HIV infection and suggests that TIM-3 may be a novel therapeutic target in chronic viral diseases.
