Dopamine affecting arteriole permeability5 answersDopamine has been shown to affect arteriole permeability. It has been found that dopamine inhibits vascular permeability factor/vascular endothelial growth factor (VPF/VEGF) induced permeability in endothelial cells by modulating the phosphorylation of tight junction proteins and weakening endothelial cell-cell adhesion. Dopamine acts through D2 dopamine receptors to induce endocytosis of VEGF receptor 2, preventing VPF/VEGF binding and subsequent signaling steps. Dopamine specifically inhibits the vascular permeabilizing and angiogenic activities of VPF/VEGF without affecting other mediators of microvascular permeability or endothelial cell proliferation or migration. Dopamine prevents the constriction of arterioles induced by noradrenaline by activating DA1 receptors, which activates adenylate cyclase. These findings suggest that dopamine plays a role in regulating arteriole permeability and may have potential therapeutic value in anti-angiogenesis therapy.
