5), we performed a flow cytometry analysis of seven T cells subpopulations (Helper T cells (Th) (CD45 +/CD5 +/CD4 +), Cytotoxic T cells (Tc) (CD45 +/CD5 +/CD8 +), Central Memory T cells (TCM) (CCR7 +/CD45RA-), Effector Memory T Cells (TEM) (CCR7-/CD45RA-), Terminal Effector T cells(TEMRA) (CCR7-/CD45RA +), Naïve T Cells (TN) (CCR7 +/CD45RA +) and Regulatory T Cells (Tregs), in a series of 31 tumor samples (Fig. 2A, B; Table S4). This evidence concerns the gene CD8A and neoplasm.
