Several studies have demonstrated that memory T cells including stem cell memory (Tscm) T cells and central memory (Tcm) T cells show superior persistence and antitumor immunity compared with effector memory T (Tem) cells and effector T (Teff) cells. Furthermore, the Tcm/Teff ratio has been reported to be a predictive biomarker of immune responses against some tumors. Thus, a system-level understanding of the mechanisms underlying the differentiation of effector and memory T cells is of increasing importance for developing immunological strategies against various tumors. This review focuses on recent advances in efficacy against tumors, the origin, formation mechanisms of memory T cells, and the role of the gut microbiota in memory T cell formation. Furthermore, we summarize strategies to generate memory T cells in (ex) vivo that, might be applicable in clinical practice.
几项研究表明,与效应记忆 T(Tem)细胞和效应 T(Teff)细胞相比,记忆 T 细胞包括干细胞记忆(Tscm)T 细胞和中央记忆(Tcm)T 细胞表现出更好的持久性和抗肿瘤免疫。此外,Tcm/Teff 比值已被报道为一些肿瘤免疫反应的预测生物标志物。因此,系统地了解效应和记忆 T 细胞分化的机制对于开发针对各种肿瘤的免疫策略变得越来越重要。本综述重点介绍了针对肿瘤的治疗效果、记忆 T 细胞的起源和形成机制以及肠道微生物群在记忆 T 细胞形成中的作用的最新进展。此外,我们总结了在(ex)体内生成记忆 T 细胞的策略,这些策略可能适用于临床实践。
