CD8A and neoplasm: Comparing immune cell levels in the tumor and normal groups, the results showed that plasma cells (P = 0.016), CD8 T cells (P = 0.026), follicular helper T cells (P = 0.005), M0 macrophages (P < 0.001), M1 macrophages (p = 0.008), activated dendritic cells (P < 0.001), resting mast cells (P < 0.001), and neutrophils (P = 0.025) were significantly differentially enriched (Figures 3C, D).
