GS levels were positively correlated with the infiltration fraction of several anti-cancer immune cells, including CD4+ memory T cells, dendritic cells (DCs), macrophage M1, and pro-cancerous T helper type 2 (Th2) cells, consistently in both the TCGA and GSE116918 cohorts (all p < 0.05) (Figure 4). The gene discussed is CD4; the disease is cancer.
