Ablation of neurons expressing agouti-related protein, but not melanin concentrating hormone, in leptin-deficient mice restores metabolic functions and fertility [Physiology]

Leptin-deficient (Lepob/ob) mice are obese, diabetic, and infertile. Ablation of neurons that make agouti-related protein (AgRP) in moderately obese adult Lepob/ob mice caused severe anorexia. The mice stopped eating for 2 wk and then gradually recovered. Their body weight fell to within a normal range for WT mice, at which point food intake and glucose tolerance were restored to that of WT mice. Remarkably, both male and female Lepob/ob mice became fertile. Ablation of neurons that express melanin-concentrating hormone (MCH) in adult Lepob/ob mice had no effect on food intake,...
