TAMs can promote the growth and survival of cancer cells and suppress the anti-tumour immune response through expression of arginase 1 (ARG1), inducible nitric oxide synthase (iNOS), IL-10, transforming growth factor β (TGFβ), and indoleamine 2,3 dioxygenase (IDO) [53]. The gene discussed is TGFB1; the disease is neoplasm.
