CD8A and neoplasm: As shown, high-risk score led to lower levels of infiltrating immune cells, including active DCs (aDCs), B cells, CD8+T cells, dendritic cells (DCs), immature dendritic cells (iDCs), macrophages, neutrophils, natural killer (NK) cells, plasmacytoid DCs (pDCs), T helper cells, T follicular helper (Tfh) cells, Th1 cells, Th2 cells, tumor infiltrating lymphocyte (TIL), and regulatory cell (Treg) in two datasets (Figures 6A, B).
