CD8A and neoplasm: Compared with the low VEGF score subtype, the high VEGF score subtype had relatively higher immune cell infiltration, including cells contributing to anti-tumor immunity (e.g., activated CD8+ T cells, type 1 T helper cells, and natural killer cells) and cells contributing to pro-tumor suppression (e.g., regulatory T cells, immature dendritic cells, and myeloid-derived suppressor cells, MDSCs) (Figure 1C).
