Adipose-derived mesenchymal stem cell-exosomes attenuate lipopolysaccharide-induced acute lung injury in mice by regulating the TGFBR2/Smad4 axis to suppress NLRP3-mediated macrophage M1 polarization and pyroptosis
Objective This study investigated whether adipose-derived mesenchymal stem cells-exosomes (ADMSC-Exo) alleviate lipopolysaccharide (LPS)-induced acute lung injury (ALI) by regulating NLRP3 inflammasome-mediated macrophage M1 polarization and pyroptosis through the miR-19b-3p/TGFBR2/Smad4 signaling axis. Methods An LPS-...
