CD8 T cell subsets were identified using established gene signatures from ovarian cancer research,13 including naive T cells (GPR183+), effector memory T cells (Tem; GZMK+), tissue‐resident T cells (Trm; IFIT3+), central memory T cells (Tcm; DNAJB1+), exhausted T cells (Tex, CXCL13+), TEMRAs (CX3CR1+) and proliferating T cells. This evidence concerns the gene CD8A and ovarian carcinoma.
