摘要
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.
