>Dr. Venema: Great presentation. Hope you have fun at the meeting. With so many different regulators of eNOS - I wonder if there is a hierarachy for regulation at different sites.
>Dr. Grover: I believe there are different pools of eNOS in endothelial cells that are activated in different ways by different combinations of allosteric effectors. This may explain why NO release in response to Ca2+ ionophore is much greater than that in response to bradykinin or other hormones. NO release in response to shear stress is even greater still and can be up to 20 times greater than in response to a hormone agonist.
