Curriculum Vitae

The goal of research in this laboratory is to understand the mechanisms of attenuated parasympathetic control of the baroreflex in experimental diabetes and chronic heart failure (CHF). The arterial baroreflex is an important component of the body's neural cardiovascular control circuit. Aortic depressor afferent nerve-endings and the nodose ganglia (NG) containing the cell bodies of the aortic baroreceptor afferent nerve (AB neuron cell) serve as the primary afferent limb of the baroreceptor reflex. Dysfunction of the primary afferent limb of the baroreceptor reflex is likely to be involved in the blunted baroreflex sensitivity observed in the diabetes and CHF state. The changes in baroreflex, endogenous substances (such as angiotensin II, nitric oxide, etc), oxidative stress (such as reactive oxygen species, ROS), and cell function (such as cell membrane excitability and ion channel function) are investigated at the molecular, cell, organ and intact animal levels.
