TAMs express chemokine (C-C motif) receptor type 2 (CCR2), a chemokine receptor that interacts with chemokine (C-C motif) ligand 2 (CCL2) and exerts a pro-tumoral role mediating tumor proliferation, angiogenesis, and chemotaxis of immune suppressive cells to the tumor stroma [35]. This evidence concerns the gene CCR2 and neoplasm.
