IL7R and neoplasm: In the OT‐I transfer model, which is widely recognized as a traditional framework for investigating the functions of tumor‐specific CD8+ T cells,[83] we found that tumor‐specific TCM‐like cells in the TdLN expressed CD44, CD62L, CD127, and TCF‐1, while maintaining low expression of PD‐1, a phenotype consistent with the recently identified TdLN‐TTSM cell.[59] The proportion of tumor‐specific TCM‐like cells in the TdLN was significantly increased after combined treatment, suggesting that the combined treatment promotes the differentiation of TTSM cells.
