Extracellular Vesicle microRNAs From Small Airways Promote Senescence and Fibrosis in COPD

Justine V. Devulder, Peter S Fenwick, Susan J. Monkley…·Peter John Barnes

This study identifies miRNA changes in COPD small airway cells and EVs, linking them to cellular senescence and fibrosis pathways.

Extracellular vesicles propagate aging in COPD airway epithelial cells by transfer of microRNA-34a

Justine V. Devulder, Jonathan R. Baker, Peter S Fenwick…·Peter John Barnes

This study shows that extracellular vesicles from COPD airway cells transfer miR-34a to healthy cells, inducing senescence by reducing SIRT1 and increasing p21CIP1.
