Ph.D. Candidates

michael-cozartMichael Cozart, B.A.
Mentor: Fang Zheng, Ph.D.
Undergraduate Degree: Ouachita Baptist University

Research Interests: Determining the functions of canonical transient receptor potential channel 3 (TRPC3) in neurovascular coupling and stroke-induced neural damage. TRPC3 is a cation channel known to regulate intracellular calcium in neurons, astrocytes, vascular smooth muscle cells (VSMCs), and cerebral endothelial cells – all the principal members of the neurovascular unit. Blockage of TRPC3 has recently been shown to be neuroprotective in a hemorrhagic model of stroke. However, the role of TRPC3 remains unclear as other studies have shown that loss of TRPC3 function is associated with a loss of endothelium-dependent dilation of cerebral arteries, which should in theory lead to an increase in stroke-induced damage. Answering these questions may lead to a pharmacological target for stroke therapy.
