B cells naive (P<0.001), B cells memory (P=0.019), T cells CD8 (P=0.004), Macrophages M0 (P=0.017), Macrophages M2 (P<0.001), Dendritic cells resting (P<0.001), Mast cells resting (P=0.043), Mast cells activated (P=0.044), there were significant infiltration differences between HCC and normal tissues (Figure 1B). Here, CD8A is linked to hepatocellular carcinoma.
