By definition, these neurons are designed to respond to noxious or tissue-damaging stimuli. A common feature of visceral inflammation is the elevation in production of sensory neuropeptides. Little is known, however, about the physiological characteristics of vagal sensory neurons induced by inflammation to produce substance P. In the present study, we show that allergic inflammation of guinea pig airways leads to the induction of substance P and CGRP production in large-diameter vagal sensory neurons. Electrophysiological and anatomical evidence reveals that the peripheral terminals of these neurons are low-threshold A\u03b4 mechanosensors that are insensitive to nociceptive stimuli such as capsaicin and bradykinin. Thus inflammation causes a qualitative change in chemical coding of vagal primary afferent neurons. The results support the hypothesis that during an inflammatory reaction, sensory neuropeptide release from primary afferent nerve endings in the periphery and central nervous system does not require noxious or nociceptive stimuli but may also occur simply as a result of stimulation of low-threshold mechanosensors. This may contribute to the heightened reflex physiology and pain that often accompany inflammatory diseases.<\/jats:p>","DOI":"10.1152\/ajplung.00353.2001","type":"journal-article","created":{"date-parts":[[2015,3,3]],"date-time":"2015-03-03T20:16:38Z","timestamp":1425413798000},"page":"L775-L781","source":"Crossref","is-referenced-by-count":143,"title":["Allergic inflammation-induced neuropeptide production in rapidly adapting afferent nerves in guinea pig airways"],"prefix":"10.1152","volume":"282","author":[{"given":"Allen C.","family":"Myers","sequence":"first","affiliation":[{"name":"Department of Medicine, The Johns Hopkins Asthma and Allergy Center, The Johns Hopkins University School of Medicine, Baltimore, Maryland 21224; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Radhika","family":"Kajekar","sequence":"additional","affiliation":[{"name":"Department of Anatomy, Physiology, and Cell Biology, School of Veterinary Medicine, University of California Davis, Davis, California 95616"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bradley J.","family":"Undem","sequence":"additional","affiliation":[{"name":"Department of Medicine, The Johns Hopkins Asthma and Allergy Center, The Johns Hopkins University School of Medicine, Baltimore, Maryland 21224; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"24","reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1002\/art.1780380519"},{"key":"B2","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.bja.a013473"},{"key":"B3","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-1838(97)00032-5"},{"key":"B4","doi-asserted-by":"publisher","DOI":"10.1038\/39807"},{"key":"B5","doi-asserted-by":"publisher","DOI":"10.1016\/0163-7258(88)90029-0"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(98)10463-4"},{"key":"B7","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.18-22-09471.1998"},{"key":"B8","doi-asserted-by":"publisher","DOI":"10.1172\/JCI119039"},{"key":"B9","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-051x.2000.027004262.x"},{"key":"B10","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4899-0744-8_1"},{"key":"B11","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.161.6.9908051"},{"key":"B12","doi-asserted-by":"crossref","first-page":"682","DOI":"10.1016\/S0022-3565(24)38188-1","volume":"289","author":"Kajekar R","year":"1999","journal-title":"J Pharmacol Exp Ther"},{"key":"B13","doi-asserted-by":"publisher","DOI":"10.1007\/BF02209015"},{"key":"B14","doi-asserted-by":"publisher","DOI":"10.1016\/0306-4522(92)90239-X"},{"key":"B15","first-page":"2161","volume":"38","author":"Lambiase A","year":"1997","journal-title":"Invest Ophthalmol Vis Sci"},{"key":"B16","doi-asserted-by":"publisher","DOI":"10.1016\/S0166-2236(96)10058-8"},{"key":"B17","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.96.16.9385"},{"key":"B18","doi-asserted-by":"publisher","DOI":"10.1038\/sj.bjp.0703172"},{"key":"B19","doi-asserted-by":"publisher","DOI":"10.1136\/gut.47.suppl_4.iv66"},{"key":"B20","first-page":"714","volume":"20","author":"Menkes CJ","year":"1993","journal-title":"J Rheumatol"},{"key":"B21","doi-asserted-by":"publisher","DOI":"10.1152\/ajpregu.2000.279.4.R1215"},{"key":"B22","doi-asserted-by":"publisher","DOI":"10.1111\/1523-1747.ep13071340"},{"key":"B23","doi-asserted-by":"publisher","DOI":"10.1038\/384360a0"},{"key":"B24","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1996.sp021703"},{"key":"B25","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1996.sp021234"},{"key":"B26","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm\/151.3_Pt_1.613"},{"key":"B27","first-page":"260","volume":"131","author":"Undem BJ","year":"1985","journal-title":"Am Rev Respir Dis"},{"key":"B28","doi-asserted-by":"publisher","DOI":"10.1007\/BF02355052"}],"container-title":["American Journal of Physiology-Lung Cellular and Molecular Physiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.physiology.org\/doi\/pdf\/10.1152\/ajplung.00353.2001","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,5,20]],"date-time":"2025-05-20T17:48:19Z","timestamp":1747763299000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.physiology.org\/doi\/10.1152\/ajplung.00353.2001"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2002,4,1]]},"references-count":28,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2002,4,1]]}},"alternative-id":["10.1152\/ajplung.00353.2001"],"URL":"https:\/\/doi.org\/10.1152\/ajplung.00353.2001","relation":{},"ISSN":["1040-0605","1522-1504"],"issn-type":[{"value":"1040-0605","type":"print"},{"value":"1522-1504","type":"electronic"}],"subject":[],"published":{"date-parts":[[2002,4,1]]}}}
