found that miR-384-5p was enriched in bone marrow mesenchymal stem cell-derived exosomes and alleviated impaired autophagy in alveolar macrophages in an LPS-induced ALI model by targeting Beclin-1 (32).Besides, MiR-377-3p released from MSCs-derived exosomes attenuated lipopolysaccharide-induced ALI by targeting the regulatory-associated protein of mTOR to induce autophagy (66). Here, BECN1 is linked to acute respiratory distress syndrome.
