ON THE COVER
miRNA-21 expression increases in the lungs of patients with idiopathic pulmonary fibrosis and mice with bleomycin-induced fibrosis, according to Liu et al. Ablating miR-21 expression—even after disease onset— attenuated the severity of lung fibrosis in mice. The image depicts an abstraction of lung architecture free of fibrosis or inflammation after miR-21 ablation. Artwork by Rachel Urkowitz ([email protected]).
