CD4 and hepatocellular carcinoma: Specifically, Nuf2 expression was positively correlated with infiltration of B cells (r=0.451, P=1.28e-18); DCs (r=0.417, P=9.35e-16); macrophages (r=0.408, P=4.30e-15); neutrophils (r=0.329, P=3.72e-10); CD4+ T cells (r=0.307, P=6.38e-09); and CD8+ T cells (r=0.298, P=1.83e-08) in HCC (Figure 3).
