Next, we noticed that in human HCC, the OS of the patients with a higher proportion of CD103+CD8+T cells was better than that of patients with a lower proportion of CD103+CD8+T cells (P = 0.0795, HR = 0.577, 95% CI: 0.252–1.325, Fig. 3A). The gene discussed is ITGAE; the disease is hepatocellular carcinoma.
