Research Description

Leptin-Angiotensin Interaction in Hypothalamic Control of Metabolism

Obesity represents an enormous biomedical, economic and social burden worldwide, and development of new therapeutic approaches depends upon understanding the molecular mechanisms that control energy balance.  Leptin is a well-known circulating hormone that contributes to energy homeostasis in part through the control of resting metabolic rate, and our team has demonstrated that the renin-angiotensin system within the arcuate nucleus of the hypothalamus mediates this control.  My ongoing work is focused on understanding the molecular connections that mediate this leptin-angiotensin cross-talk within the brain.
