  • Publication number: 20020173481
    Abstract: Vascular endothelia are subject to atherosclerotic and arteriostenotic effects transduced by molecules, such as thrombin, IL-3 and VEGF which can lead to vessel occlusion or stenosis. An endothelial signaling pathway involving the Bmx tyrosine kinase contributes to normal endothelial nonthrombogenic, inflammatory and growth conditions of arterial vessels, and regulation of the pathway can treat or prevent pathological conditions in the vessel walls.
