Article Title: M2-type macrophage nanovesicles regulate the inflammatory response after necrotizing enterocolitis by inducing M1 to M2-like macrophage polarization

doi: 10.3389/fcimb.2025.1664897

Figure Lengend Snippet: Polarization and identification of M1- and M2- macrophages. After treatment with LPS/IL4. (A) The morphology of M0-, M1- and M2-type macrophages under microscope (bar:50μm). (B) The detection of CD86 and CD206 (M1- and M2-type macrophages marker) by flow cytometer. (C) The protein expression levels of CD86 and CD206, and β-actin are measured using western blot analysis and the relative expression levels are plotted. (D-G) The Inflammatory factor expression levels of IL4, TGFβ, IL6 and TNFα are measured using ELISA analysis and the relative expression levels are plotted. (H) The fluorescence signal change of TGFβ and TNFα was shown after the treatment of LPS/IL4 (bar:10μm). * p < 0.05 and ** p < 0.01 vs control.
