Profile

Summary of Current Research

My lab is interested in understanding the changes that occur in the cardiac innervation following myocardial infarction (a heart attack). Alterations in the sympathetic innervation of the heart after myocardial infarction can trigger arrhythmias and sudden cardiac death. These neuronal changes are not well understood, but blocking cardiac receptors for the neurotransmitter norepinephrine (NE) can help prevent arrhythmias. We are trying to understand the molecular basis for these changes in noradrenergic function, investigating the regulation of neuronal proteins that synthesize, store, and remove NE, and the genes that encode them. We are also examining the role of neurotrophins in post-infarct denervation and nerve sprouting/regeneration. Cardiac nerve sprouting in humans has been directly linked to cardiac pathology and sudden cardiac death. We use a variety of molecular, biochemical, and histological techniques to investigate the regulation of these proteins and genes, using cell lines, primary neuronal cultures, and whole animal studies.
