Research Description

My research focuses on understanding how stress, obesity and aging affect neuroendocrine regulation of blood pressure with an aim to identify novel therapeutic targets for the treatment of hypertension and cardiovascular diseases.

The paraventricular nucleus of the hypothalamus (PVN) is a complex structure composed of several subgroups of neurons involved in maintaining homeostasis, regulating autonomic and endocrine responses to internal or external stressors and controlling food intake and energy expenditure. We are investigating these regulatory mechanisms within the PVN in order to better understand the ways stress, changes in diet, age and the combination of these factors lead to elevations in blood pressure. Ongoing projects are aimed to reveal the roles of neurotrophins such as brain-derived neurotrophic factor and nerve growth factor within the PVN and their involvement in acute stress responses, regulation of food intake and energy balance, neuroplasticity and enhancing antioxidant capacity.

We use whole animal and molecular techniques including radiotelemetric measurement of blood pressure in conscious animals, sympathetic nerve activity recording, stereotaxic brain injections of pharmacological agents and viral vectors for in vivo gene transfer, immunohistochemistry, fluorescent and confocal microscopy, Western blot, ELISA and quantitative real-time PCR.
