Airway remodeling in bronchial asthma can be inhibited by disrupting the epithelial mesenchymal transition (EMT) of activated airway cells. Exosomes, as key mediators intercellular communication, have been implicated pathophysiology asthma-related inflammation, remodeling, and hyperresponsiveness. This study aimed to investigate role M2 macrophage-derived exosomes (M2φ-exos) modulating TGF-β1-induced EMT (BEAS-2B) cells elucidate underlying molecular mechanism, if any. THP-1 were induced differentiate into macrophages via phorbol 12-myristate 13-acetate (PMA) IL-4. Exosomes subsequently isolated purified ultracentrifugation. M2φ-exos expression was characterized protein marker levels, transmission electron microscopy imaging, nanoparticle tracking analysis. BEAS-2B exposed determine latter's effects. successfully differentiated macrophages, confirmed vitro flow cytometry. The presented typical cup-shaped structures expressed CD81 TSG101. TGF-β1 induction altered morphological characteristics TGF-βRI/Smad2/3 signaling pathway, leading increased Snail, Vimentin Collagen 1 decreased E-cadherin. After exosome or SB431542 induction, reversed. GW4869, an release inhibitor, exhibited ability block beneficial effects exosomes. M2Φ-exos through pathway. novel insight may important implications for asthma, particularly addressing remodeling.
