Figure 1.

Data from COAD and READ showed that the expression of M2 macrophage increases with the increasement of Treg cells. In Treg cells and M2 macrophage cells, PD-1 gene expression increases with the increasement of Tim-3.

Correlations between Tregs and M2 macrophages in colorectal cancer. (a) A positive correlation between Treg coding gene FOXP3 with M2 macrophage. M2 macrophage coding genes CD163 and MRC1 presented high positive correlations with tumor infiltrated Tregs in both COAD (n=458) and READ (n=166). (b) Cytokines IL-10 coding gene IL-10 and TGF-β coding gene TGF-β1 demonstrated a high positive correlation neither in Tregs or M2 macrophages in CRC patients’ cohorts (COAD and READ).
