biostudies-literatureUnknown14Jandl K<h4>Background</h4>Immune cell recruitment, endothelial cell barrier disruption, and platelet activation are hallmarks of lung injuries caused by COVID-19 or other insults which can result in acute respiratory distress syndrome (ARDS). Basement membrane (BM) disruption is commonly observed in ARDS, however, the role of newly generated bioactive BM fragments is mostly unknown. Here, we investigate the role of endostatin, a fragment of the BM protein collagen XVIIIα1, on ARDS associated cellular functions such as neutrophil recruitment, endothelial cell barrier integrity, and platelet aggregation <i>in vitro</i>.<h4>Methods</h4>In our study we analyzed endostatin in plasma and post-mortem lung specimens of patients with COVID-19 and non-COVID-19 ARDS. Functionally, we investigated the effectFrontiers in immunology1188079https://www.ebi.ac.uk/biostudies/studies/S-EPMC10241244biostudies-literatureBasement membrane product, endostatin, as a link between inflammation, coagulation and vascular permeability in COVID-19 and non-COVID-19 acute respiratory distress syndrome.PMC10241244Berg JLOlschewski HWygrecka MHeinemann ASeeliger BZacharias MBorek IKwapiszewska GFliesser EBirnhuber ASchmidt JJGorkiewicz GJandl KDavid SWelte TfalseBasement membrane product, endostatin, as a link between inflammation, coagulation and vascular permeability in COVID-19 and non-COVID-19 acute respiratory distress syndrome.<h4>Background</h4>Immune cell recruitment, endothelial cell barrier disruption, and platelet activation are hallmarks of lung injuries caused by COVID-19 or other insults which can result in acute respiratory distress syndrome (ARDS).
