Neuronal control of energy homeostsasis in obesity and diabetes
Using a polygenic model of diet-induced obesity (DIO)that mimics many of the characteristics of obesity and type 2 diabetes mellitus in humans, we examine the factors that predispose individuals who carry the genes for obesity to become obese. Current focus is on the effects of manipulating the maternal and postnatal environments to prevent the development of DIO. This includes altering maternal nutritional status, the hormonal milieu of the pups and postweaning exercise. In addition, we study the role that specialized metabolic sensing neurons in the brain play in the regulation of energy and glucose homeostasis. This includes neurons which alter their activity when ambient levels of glucose and long chain fatty acids change in their environment. These neurons appear to be critical sensors that allow the brain to monitor and then alter the metabolic status of the body.
