Forging a link between brain and bone

The adipose-derived hormone leptin is well known for its influence on feeding behavior. Animals with genetic defects in leptin signaling become obese when supplied unlimited food. However, even when food supply is limited to prevent obesity, leptin still exerts profound effects on various organs, including the bones. These effects are mediated by the central nervous system, specifically hypothala...
