Description:
Two groups of mediators, the neuropeptides substance P and K and the monocyte-derived cytokines, interact in the neural regulation of immunological and inflammatory responses. Substance P, substance K, and the carboxyl-terminal peptide SP(4-11) induce the release of interleukin-1, tumor necrosis factor-alpha, and interleukin-6 from human blood monocytes. The neuropeptide effects occur at low doses, are specific as shown by inhibition studies with a substance P antagonist, and require de novo protein synthesis. Since monocyte-derived cytokines regulate multiple cellular functions in inflammation and immunity and since neuropeptides can be released from peripheral nerve endings into surrounding tissues, these findings identify a potent mechanism for nervous system regulation of host defense responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lotz, M -- Vaughan, J H -- Carson, D A -- AI10386/AI/NIAID NIH HHS/ -- AR21175/AR/NIAMS NIH HHS/ -- AR25443/AR/NIAMS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1988 Sep 2;241(4870):1218-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Basic and Clinical Research, Research Institute of Scripps Clinic, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2457950" target="_blank"〉PubMed〈/a〉
