Alveolar Epithelial Cell-Derived Exosomes Regulate Autophagy through miR-450b-5p/HDAC7 to Improve Pulmonary Fibrosis

A cell fibrosis model was constructed using TGF-β, and a mouse fibrosis model was constructed with bleomycin, treated with alveolar epithelial cell-derived exosomes, which was interfered with by treatment with a miR-450b-5p inhibitor.
