The results indicated that CEP55 expression was significantly related to the infiltration level of B cells (R = 0.475, p = 1.02e − 20), CD4+ T cells (R = 0.345, p = 4.57e − 11), CD8+ T cells (R = 0.367, p = 2.44e − 12), macrophages (R = 0.5, p = 6.20e − 23), neutrophils (R = 0.345, p = 4.53e − 13), and dendritic cells (R = 0.473, p = 2.37e − 20) in HCC (Figure 10(b)). This evidence concerns the gene CD4 and hepatocellular carcinoma.
