IFN-γ promotes the M2 polarization of macrophages. A The expression of CD68 was measured by RT‒qPCR; B The expression of CD163, CD206 and IDO1 was detected by Western blot; C The levels of IL-6, IL-10, IL-13 and TNF-α were measured by ELISA; D The phagocytosis of TAMs was detected by flow cytometry; E Phagocytic function of TAMs was observed by cell probe staining. Compared with the THP-1 group or NC group, ^*P < 0.05, ^**P < 0.01, ^***P < 0.001; compared with the IL-4 group,^#P < 0.05, ^##P < 0.01, ^###P < 0.001
