Figure Lengend Snippet: MIIP suppresses M2 macrophage polarization and decreases macrophage-derived IL10 levels in a co-culture system. MIIP knockdown in SW480 cells increased CD163 expression (A) and CD206 levels (B) in PMA-induced THP-1 cells, the CD163 level in the co-culture medium (C), the mRNA expression of IL-10 (D), and the IL10 levels (E) in PMA-induced THP-1 cells. MIIP overexpression in CT26 cells decreased the CD163 level in the co-culture medium of the co-cultured system (F) and macrophage-derived IL10 expression (G) and IL-10 levels in RAW264.7 cells (H). Effects of MIIP knockdown, STING knockdown, and dual MIIP and STING knockdown in CRC cells on CD163 expression in co-cultured PMA-treated THP-1 cells (I), CD163 levels in the co-culture medium (J), CD206 levels in PMA-treated THP-1 cells (K), and macrophage-derived IL10 expression (L) and IL-10 levels (M). All data are presented as the means ± SDs ( n = 3). * P < 0.05, ** P < 0.01, *** P < 0.001, and **** P < 0.0001; scale bar, 10 μm.
