摘要
IL-15 属于常见的γ链细胞因子家族，具有多种免疫功能。IL-15 是一种平衡细胞因子，对 NK 细胞和记忆性 CD8+ T 细胞的发育和维持至关重要。此外，IL-15 还在 CD8+ T 细胞的活化、效应功能、组织驻留和衰老过程中发挥关键作用。IL-15 还能激活虚拟记忆 T 细胞、粘膜相关不变 T 细胞和 γδ T 细胞。最近，IL-15 被强调为 TCR 依赖性活化 T 细胞的主要触发因子。这一机制参与了包括病毒感染和慢性炎症性疾病在内的多种疾病的 T 细胞介导的免疫发病机制。深入了解 IL-15 介导的 T 细胞反应及其内在机制可优化治疗策略，改善 T 细胞介导的免疫发病机制对宿主造成的伤害。本综述重点介绍了最近在理解 IL-15 在各种宿主条件下与 T 细胞反应和免疫发病机制有关的作用方面取得的进展。
IL-15 belongs to the common gamma chain cytokine family and has pleiotropic immunological functions. IL-15 is a homeostatic cytokine essential for the development and maintenance of NK cells and memory CD8+ T cells. In addition, IL-15 plays a critical role in the activation, effector functions, tissue residency, and senescence of CD8+ T cells. IL-15 also activates virtual memory T cells, mucosal-associated invariant T cells and γδ T cells. Recently, IL-15 has been highlighted as a major trigger of TCR-independent activation of T cells. This mechanism is involved in T cell-mediated immunopathogenesis in diverse diseases, including viral infections and chronic inflammatory diseases. Deeper understanding of IL-15-mediated T-cell responses and their underlying mechanisms could optimize therapeutic strategies to ameliorate host injury by T cell-mediated immunopathogenesis. This review highlights recent advancements in comprehending the role of IL-15 in relation to T cell responses and immunopathogenesis under various host conditions.
