Description:
The endogenous neuropeptide cholecystokinin, when administered systemically or perispinally, potently antagonizes opiate analgesia produced by foot shock and morphine. Nonopiate foot-shock analgesia is not reduced by this neuropeptide. The spinal cord appears to be a critical site of cholecystokinin action. These experiments suggest a physiological role for cholecystokinin as a specific opiate antagonist in analgesia-mediating systems. A similar mode of action may explain other behavioral effects of cholecystokinin, such as suppression of food intake.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Faris, P L -- Komisaruk, B R -- Watkins, L R -- Mayer, D J -- New York, N.Y. -- Science. 1983 Jan 21;219(4582):310-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6294831" target="_blank"〉PubMed〈/a〉
