CD8A and neoplasm: Next, we discovered that the level of immune cell infiltration in the high-NRGPS group in TCGA cohort was higher, especially with respect to B-cells, CD8 T cells, dendritic cells, immature dendritic cells, Macrophages cells, mast cells, neutrophils, plasmacytoid dendritic cells, helper T cells, tumor-infiltrating lymphocytes, and regulatory T cells (than in the low-NRGPS group) (Figure 8C).
