A disintegrin and metalloproteinase 15-mediated glycocalyx shedding contributes to vascular leakage during inflammation

摘要

AimsEndothelial hyperpermeability exacerbates multiple organ damage during inflammation or infection. The endothelial glycocalyx, a protective matrix covering the luminal surface of endothelial cells (ECs), undergoes enzymatic shedding during inflammation, contributing to barrier hyperpermeability. A disintegrin and metalloproteinase 15 (ADAM15) is a sheddase capable of cleaving the ectodomains of membrane-bound molecules. Herein, we tested whether and how ADAM15 is involved in glycocalyx shedding and vascular leakage during sepsis.
