不同亚群的记忆性CD8 + T细胞对感染黏膜部位的回忆应答所起的作用了解甚少。在此,我们分析了小鼠对呼吸道病毒感染的CD8 + T细胞回忆应答,并证明激活标志物,如CD27和CD43,界定了记忆性CD8 + T细胞的三个不同亚群,它们在引发回忆应答的能力上存在差异。这些亚群不同于效应记忆和中枢记忆亚群,协同表达与激活状态相关的其他标志物,包括CXCR3、CD127和杀伤细胞凝集素样受体G1,并且在预测记忆T细胞介导回忆应答的能力方面优于CD62L。此外,疫苗激发这些记忆T细胞亚群的能力可预测回忆应答的效果。这些发现拓展了我们对回忆应答如何产生的理解,并表明激活和迁移标志物界定了记忆T细胞不同且不相关的特征。
The contributions of different subsets of memory CD8+ T cells to recall responses at mucosal sites of infection are poorly understood. Here, we analyzed the CD8+ T cell recall responses to respiratory virus infection in mice and demonstrate that activation markers, such as CD27 and CD43, define three distinct subpopulations of memory CD8+ T cells that differ in their capacities to mount recall responses. These subpopulations are distinct from effector– and central–memory subsets, coordinately express other markers associated with activation status, including CXCR3, CD127, and killer cell lectin-like receptor G1, and are superior to CD62L in predicting the capacity of memory T cells to mediate recall responses. Furthermore, the capacity of vaccines to elicit these memory T cell subpopulations predicted the efficacy of the recall response. These findings extend our understanding of how recall responses are generated and suggest that activation and migration markers define distinct, and unrelated, characteristics of memory T cells.
