人们普遍认为,CD 4 + T细胞的作用是协调适应性免疫系统的不同分支,以形成针对病原体的有效反应并调节非必需或有害的活动。然而,越来越多的证据表明,效应CD 4 + T细胞本身可以直接显示出有效的抗病毒活性。溶细胞性CD 4 + T细胞的存在已在人类和动物模型中对许多病毒感染的免疫应答中得到证实,并且它们可能在体内病毒复制的控制中发挥关键作用。本文介绍了目前对病毒特异性溶细胞性CD 4 + T细胞的研究,重点是HIV-1感染和这种免疫反应对疫苗设计的影响。
It is generally believed that the role of CD4+ T cells is to coordinate the different arms of the adaptive immune system to shape an effective response against a pathogen and regulate nonessential or deleterious activities. However, a growing body of evidence suggests that effector CD4+ T cells can directly display potent antiviral activity themselves. The presence of cytolytic CD4+ T cells has been demonstrated in the immune response to numerous viral infections in both humans and in animal models and it is likely that they play a critical role in the control of viral replication in vivo. This article describes the current research on virus-specific cytolytic CD4+ T cells, with a focus on HIV-1 infection and the implications that this immune response has for vaccine design.
