The effect of the melanocortin agonist, MT-II, on the defended level of body adiposity.

A wide range of experimental evidence implicates a critical role for melanocortin signaling in the control of food intake and body adiposity. Melanocortin receptor agonists such as MT-II potently reduce food intake and body weight, making such agonists potential therapeutics for obesity. The critical concept addressed by the present experiments is whether the homeostatic effects of melanocortin agonists directly regulate food intake or whether the effects on food intake are secondary, with the primary effects being the regulation of body weight and adiposity.
