Biography & Current Research

Research Synopsis

Our research program is focused on neurotransmitter regulation and function in the paraventricular nucleus of the hypothalamus in normotensive and hypertensive animals. The paraventricular nucleus serves as a crossroads in integrating homeostatic and allostatic sensory stimuli to regulate the sympathetic nervous system, neuroendocrine function, ingestive behavior, stress responses, and the immune system. Circulating hormones such as angiotensin, aldosterone, and leptin stimulate neural pathways that activate the paraventricular nucleus which, in turn, modulates descending pathways to regulate the sympathetic nervous system and blood pressure. Little is known about neurotransmission and signaling mechanisms in the paraventricular nucleus in response to these chemical and neural stimuli. We use a number of methodological approaches to study the whole animal response to experimental hypertension – microinjection, microdialysis of neural tissue, and biochemical and molecular analyses are employed to understand the relationship between neurotransmitter release and blood pressure control. Models of sodium-dependent hypertension and obesity-related hypertension are studied to gain insights into the factors triggering and sustaining the hypertensive process.
