Description:
The endogenous opioid system is involved in stress responses, in the regulation of the experience of pain, and in the action of analgesic opiate drugs. We examined the function of the opioid system and mu-opioid receptors in the brains of healthy human subjects undergoing sustained pain. Sustained pain induced the regional release of endogenous opioids interacting with mu-opioid receptors in a number of cortical and subcortical brain regions. The activation of the mu-opioid receptor system was associated with reductions in the sensory and affective ratings of the pain experience, with distinct neuroanatomical involvements. These data demonstrate the central role of the mu-opioid receptors and their endogenous ligands in the regulation of sensory and affective components of the pain experience.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zubieta, J K -- Smith, Y R -- Bueller, J A -- Xu, Y -- Kilbourn, M R -- Jewett, D M -- Meyer, C R -- Koeppe, R A -- Stohler, C S -- R01 DE 12059/DE/NIDCR NIH HHS/ -- R01 DE 12743/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 2001 Jul 13;293(5528):311-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry and Mental Health Research Institute, Medical School, The University of Michigan, Ann Arbor, MI 48104-1687, USA. zubieta@umich.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11452128" target="_blank"〉PubMed〈/a〉
