Sating the Ravenous Brain: Researchers Quell Hunger Neurons in Fruit Flies

Two decades ago, the discovery of neuropeptide Y ( NPY ), a peptide in the mammalian brain involved in food-seeking behavior, sparked a search for a weight-loss remedy that could interfere with its activity. Eventually the promise of other drug targets, along with the possible side effects of targeting NPY, put a damper on the effort--until now.
