摘要

During an inflammatory response, leukocytes and fluids from the blood must reach the affected tissue. Tight regulation of endothelial junctions of the vascular endothelium is a critical molecular mechanism for controlling such events. VE-cadherin is a vascular endothelial adhesion molecule, specifically and exclusively expressed by endothelial cells, that controls integrity of blood vessels. In this issue of Nature Immunology, Wessel et al. report constitutive phosphorylation of VE-cadherin at Tyr731 in vivo and demonstrate that dephosphorylation of that residue contributes to leukocyte extravasation, whereas mediator-induced phosphorylation of VE-cadherin at Tyr685 results in vascular permeability.
