CD4 and prostate adenocarcinoma: As shown in the results, we found a significant positive association between SLC2A1 expression and the immune infiltration value of myeloid-derived suppressor cells (MDSCs) in ACC (r = 0.603), LUAD (r = 0.526), TGCT (r = 0.562) and PAAD (r = 0.564); endothelial cells in LGG (r = 0.501), common lymphoid progenitors in TGCT (r = 0.609); neutrophils in THCA (r = 0.528); CD4+ T cells in PRAD (r = 0.525) and cancer-associated fibroblast in UVM (r = 0.550) (Figure 10A).
