Associate Professor, Cardiovascular Medicine and Pharmacology and Toxicology
The overall emphasis of Dr. David X. Zhang's research is to understand the cellular mechanisms by which the endothelium regulates blood vessel tone in both normal physiological conditions and disease states, such as ischemic heart disease and hypertension.
My current research is focused on understanding the transient receptor potential vanilloid 4 channels to angiotensin II-induced impairment of vasodilation in animals and humans. I am also interested in the role of vascular smooth muscle potassium channels in hydrogen peroxide-induced vasodilation in human arterioles, in health and disease.
My current research is focused on determining whether arachidonic acid (AA) serves as a key upstream mediator of flow-mediated dilation (FMD) in human coronary arteriole (HCA) and define the molecular mechanisms by which AA activates the transient receptor potential vallinoid type 4 (TRPV4) channel in coronary endothelial cells.
