Research Interest

My research interests focus on how cannabinoids regulate the hypothalamic feeding circuitry to affect changes in feeding behavior and energy homeostasis in male and female subjects, and how gonadal steroids modulate this interaction. I use state-of-the-art instrumentation to assess cannabinoid-induced changes in daily and hourly food intake, as well as meal size, frequency and duration, core body temperature and weight gain/loss, and how these changes correlate with alterations in neurotransmitter release and cell excitability at anorexigenic proopiomelanocortin (POMC) synapses within the hypothalamic arcuate nucleus. I recently have discovered that males are much more sensitive to the appetite-modulating properties of CB1 receptor agonists and antagonists than females, which correlates with marked sex differences in the pre- and post synaptic actions of cannabinoids at POMC synapses. These findings indicate that gender should be taken into account when considering the use of cannabinoids in the treatment of HIV/AIDS- or cancer-related cachexia, or obesity.
