LGMN regulates endothelial-to-mesenchymal transition via the p38 MAPK pathway to promote pulmonary fibrosis
Idiopathic pulmonary fibrosis (IPF) is a progressive, fatal lung disease driven by fibroblast activation and extracellular matrix deposition. Endothelial-to-mesenchymal transition (EndMT) critically contributes to vascular injury and fibrotic remodeling in IPF. Legumain (LGMN), a lysosomal cysteine protease involved in...
