As is shown in Figure 8(a), significant proportions of resting mast cells, neutrophils, CD8 T cells, and total T cells were found to be enriched in HCC patients with low risk score, while only activated mast cells were found to be enriched at patients with high risk score (all p < 0.05, Figure 8(a)). The gene discussed is CD8A; the disease is hepatocellular carcinoma.
