As shown in Figure 11E, the levels of immune cell infiltration in the high-risk group were generally lower than those in the low-risk group, especially for CD8+T cells, neutrophils, natural killer (NK) cells, T helper (Th) cells (Tfh, Th1, and Th2 cells), tumor-infiltrating lymphocytes (TILs) and regulatory T (Treg) cells. This evidence concerns the gene CD8A and neoplasm.
