Cell–cell junctional mechanotransduction in endothelial remodeling

Mechanotransduction in endothelial cell migration.

The migration of endothelial cells (ECs) plays an important role in vascular remodeling and regeneration. EC migration can be regulated by different mechanisms such as chemotaxis, haptotaxis, and mechanotaxis. This review will focus on fluid shear stress-induced mechanotransduction during EC migration. EC migration and mechanotransduction can be modulated by cytoskeleton, cell surface receptors...

Flow-mediated endothelial mechanotransduction.

Mechanical forces associated with blood flow play important roles in the acute control of vascular tone, the regulation of arterial structure and remodeling, and the localization of atherosclerotic lesions. Major regulation of the blood vessel responses occurs by the action of hemodynamic shear stresses on the endothelium. The transmission of hemodynamic forces throughout the endothelium and th...

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

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 i...

Vascular Endothelial-Junctional Adhesion

Roles of YAP in mediating endothelial cell junctional stability and vascular remodeling

Angiogenesis is a complex process involving dynamic interaction of various cell to cell interactions. Endothelial cell interactions regulated by growth factors, inflammatory cytokines, or hemodynamic stress are critical for balancing vascular quiescence and activation. Yes-associated protein (YAP), an effector of Hippo signaling, is known to play significant roles in maintaining cellular homeos...
