As shown in Figure 7F, the infiltration of T cell gamma delta, T cell regulatory (Tregs), T cell follicular helper, T cell CD4+ memory activated, T cell CD8+, and Macrophage M0 were increased in HCC patients with high-risk, while T cell CD4+ naive and CD4+ memory resting cells were higher in the low-risk group. The gene discussed is CD8A; the disease is hepatocellular carcinoma.
