流感病毒感染会诱导一种强大的初始先天免疫反应,从而限制病毒复制和传播的程度。然而,有效的(并最终)清除呼吸道内的病毒需要适应性免疫系统随后的激活、快速增殖、募集和表达效应器活性,该系统由产生抗体的B细胞和具有不同功能的流感特异性T淋巴细胞组成。这些T淋巴细胞随后的效应器活动最终决定(与抗体一起)宿主清除病毒的能力和组织损伤的程度。在这篇综述中,我们描述了这种效应T细胞对流感病毒感染的反应。基于大量在实验环境(即小鼠模型)中获得的信息,我们将阐述调节诱导获得性免疫T细胞对流感的反应的因素,这些被激活的T细胞所显示的效应活性,这些效应机制表达的潜在机制,以及这些T细胞在感染肺中的激活/分化的原位控制。
Influenza virus infection induces a potent initial innate immune response, which serves to limit the extent of viral replication and virus spread. However, efficient (and eventual) viral clearance within the respiratory tract requires the subsequent activation, rapid proliferation, recruitment, and expression of effector activities by the adaptive immune system, consisting of antibody producing B cells and influenza-specific T lymphocytes with diverse functions. The ensuing effector activities of these T lymphocytes ultimately determine (along with antibodies) the capacity of the host to eliminate the viruses and the extent of tissue damage. In this review, we describe this effector T cell response to influenza virus infection. Based on information largely obtained in experimental settings (i.e., murine models), we will illustrate the factors regulating the induction of adaptive immune T cell responses to influenza, the effector activities displayed by these activated T cells, the mechanisms underlying the expression of these effector mechanisms, and the control of the activation/differentiation of these T cells, in situ, in the infected lungs.
