Our investigation revealed a positive correlation between the expression of CLEC7A and monocyte chemoattractant factors (CCL2, CCL5) as well as factors implicated in M2 macrophage polarization (TGF-β1, CSF-1) in glioma samples obtained from both TCGA and CGGA databases (Figures 6G, H). Here, TGFB1 is linked to central nervous system cancer.
