Abstract/OtherAbstract:
The role of neuropeptide Y (NPY) in feeding behavior and zinc deficiency-induced anorexia has been controversial because hypothalamic NPY levels are elevated in both zinc deficiency and food restriction. A recent report shows that while NPY is released from terminals in the paraventricular nucleus of the hypothalamus of food-restricted animals, this release is significantly impaired in zinc-deficient animals. Zinc deficiency may therefore cause anorexia by inhibiting the release of NPY that is required for receptor activation.
