CD8A and cancer: We found that the score strongly correlated with the infiltration of anti-cancer immune cells in the METABRIC and GSE96058 cohorts, including CD8+ T cells, CD4+ memory T cells, M1 macrophages, and plasmacytoid dendritic cells (pDC) (Fig. 2a; all spearman’s rank correlation (r) > 0.700, all p < 0.01), but not with T helper type 1 (Th1) cells or natural killer (NK) cells.
