Deskripsi
Severe COVID-19 is associated with epithelial and endothelial barrier dysfunction, however, the molecular pathways resulting in endothelial barrier dysfunction and vascular leakage are only sparsely understood. Here, Biering et al. show that SARS-CoV-2 spike protein is sufficient to induce barrier dysfunction and vascular leak. They show a role for integrins, TGF-beta, ECM remodeling enzymes, and glycosaminoglycans in this S-mediated barrier dysfunction.
