TGFB1 and neoplasm: We further revealed that Arg-1 (P < 0.001), NOX-2 (P < 0.05), TGF-β (P < 0.05), and PD-L1 (P < 0.05) were significantly higher from Lect2−/− EOC than Lect2+/+ EOC (Fig. 6B), supporting their potential for inhibiting the tumor-infiltrating lymphocytes and silencing the immune response.
