The proportions of CD8+ T cell (P = 0.004), resting memory CD4+ T cells (P = 0.006), gamma delta T cells (P < 0.001), resting NK cell (P = 0.001), monocytes (P = 0.004), M2 macrophages (P = 0.021), and neutrophils (P < 0.001) in HCC were significantly lower than in healthy controls (Figure 7(b)). This evidence concerns the gene CD8A and hepatocellular carcinoma.
