Enhanced anti-tumour immunity requires the interplay between resident and circulating memory CD8⁺ T cells.

ABSTRACT: The goal of successful anti-tumoural immunity is the development of long-term protective immunity to prevent relapse. Infiltration of tumours with CD8⁺ T cells with a resident memory (Trm) phenotype correlates with improved survival. However, the interplay of circulating CD8⁺ T cells and Trm cells remains poorly explored in tumour immunity. Using different vaccination strategies that fine-tune the generation of Trm cells or circulating memory T cells, here we show that, while both subsets are sufficient for anti-tumour immunity, the presence of Trm cells improves anti-tumour efficacy. Transferred central memory T cells (Tcm) generate Trm cells following viral infection or tumour challenge. Anti-PD-1 treatment promotes infiltration of transferred Tcm cells within tumou
