As shown in Figures 5B–D, FDX1 expression was negatively correlated with tumor infiltrating immune cells including CD8+ T cells, CD4+ T cells, macrophage etc. In a large part of tumor types we analyzed such as ACC, COAD, KIRC, LAML, LUAD, STAD, THCA. This evidence concerns the gene CD4 and adrenal cortex carcinoma.
