ABSTRACT
OBJECTIVE:
Researchers have investigated miR-130b-3p in lung disease pathology, such as lung fibrosis. The present study was performed to elucidate the miR-130b-3p-involved mechanism in acute lung injury (ALI) through delivery by mesenchymal stem cells-derived exosomes (MSCs-Exo).METHODS:
ALI mouse models were induced via intratracheal administration of lipopolysaccharide (LPS) and treated with MSCs-Exo. Lung dry-wet (W/D) ratio, inflammatory factors in the bronchoalveolar lavage fluid, pathological damage and apoptosis in the lung tissues were analyzed. Expression levels of miR-130b-3p and TGFBR1 were measured in the mouse lung tissues, and the interaction between miR-130b-3p and TGFBR1 was studied.RESULTS:
MSCs-Exo relieved LPS-induced ALI in mice by reducing lung W/D ratio and inflammatory response, and attenuating lung tissue pathological damage and reducing the alveolar cell apoptosis. miR-130b-3p delivery by MSCs-Exo reduced LPS-induced ALI in mice. TGFBR1 was determined to be a downstream target gene of miR-130b-3p. Inhibition of TGFBR1 could remit LPS-induced ALI in mice. The protection mediated by MSCs-Exo carrying miR-130b-3p could be rescued by elevating TGFBR1 expression.CONCLUSION:
miR-130b-3p delivery by MSCs-Exo confers protection on ALI in mice via the downregulation of TGFBR1.Palavras-chave
