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
ADMSC-derived exosomes alleviate LPS-induced acute lung injury by delivering miR-19b-3p to inhibit the TGFBR2/Smad4 signaling pathway, thereby suppressing NLRP3-mediated macrophage M1 polarization and pyroptosis and reducing lung epithelial cell apoptosis.
