TGFB1 and TGFB2 have been identified as the most highly expressed tumor-promoting cytokine in the TME of gliomas [47,48,49,50,51,52], prompting us to characterize the abundance of TGFB1 and TGFB2 mRNA addition to the upregulation of TAM cell surface markers. This evidence concerns the gene TGFB1 and central nervous system cancer.
