Our laboratory is working on understanding how nerve systems (peripheral (e.g sciatic and vagus nerves) or central (brain)) sense and use nutrients (with a special interest for fat -either dietary or secreted by the gut microbiota (bacteria that lives in our gut)-). We know that this sensing is important for i) proper central control of energy balance and cognition, and ii) for proper peripheral nerve system function. Others and we found that this ‘’fat sensing’’ by nerve systems is altered in Aging and when Western-diet is consumed leading to overweight, type II Diabetes and pain. Our research goal is to use in vivo cell-specific mouse model and ex-vivo nerve system cultures (e.g brain slices) to unmask pathways leading to hyperphagia, glucose intolerance and pain observed in Obesity (and metabolic syndrome). Our aim is to find targets to decrease bodyweight, improve insulin sensitivity and peripheral pain. We strive to test interventions on Obese mice cohorts and to understand the molecular signatures underlying the improvement.
