Local VE-cadherin mechanotransduction triggers long-ranged remodeling of endothelial monolayers.

ABSTRACT: In this study, we present results demonstrating that mechanotransduction by vascular endothelial cadherin (VE-cadherin, also known as CDH5) complexes in endothelial cells triggers local cytoskeletal remodeling, and also activates global signals that alter peripheral intercellular junctions and disrupt cell-cell contacts far from the site of force application. Prior studies have documented the impact of actomyosin contractile forces on adherens junction remodeling, but the role of VE-cadherin in force sensation and its ability to influence endothelial cell and tissue mechanics globally have not been demonstrated. Using mechanical manipulation of VE-cadherin bonds and confocal imaging, we demonstrate VE-cadherin-based mechanotransduction. We then demonstrate that it requires homophilic VE-ca
