Research Interests

The objective of the research in this laboratory is to investigate the regulation of adrenergic neuroeffector events in the cardiovascular system. A variety of physiological, pharmacological, cellular and molecular techniques are used to define interaction of these neurohormonal systems in several experimental preparations of different species, both in vitro and in vivo.

The specific aims are: 1) characterization of receptors and the underlying signal transduction mechanisms (coupling of receptors to phospholipases via different G proteins) involved in adrenergically-induced release of arachidonic acid for prostaglandin synthesis; 2) investigation of the mechanism of action of arachidonic acid metabolites on release of the adrenergic transmitter ; and 3) examination of the mechanism of interaction of angiotensins and adrenergic nervous system in the regulation of cardiovascular function.
