Figure 4(b) shows the relationship between expression of EIF4G2 and 28 types of TILs across human cancers. As presented in Figures 4(c)–4(f), the expression of EIF4G2 was correlated with abundance of Type 2 T helper cells (Th2; r = 0.196, P = 6.17e − 05), activated CD4 T cells (Act _CD4; r = 0.163, P = 0.00086), effector memory CD4 T cells (Tem _CD4; r = 0.164, P = 0.000832), and immature DCs (iDCs; r = 0.122, P = 0.013). The gene discussed is CD4; the disease is cancer.
