    • After unilateral adjuvant-induced inflammation, expression of neuropeptides believed to be involved in the inflammatory response, e.g. substance P and calcitonin gene-related peptide (CGRP), is upregulated in innervating sensory neurons. Islet amyloid polypeptide (IAPP) is structurally related to CGRP and constitutively expressed in sensory CGRP-containing neurons; the role of IAPP in sensory neurons is unknown. To examine whether IAPP could play a role in inflammation, IAPP expression in L5 dorsal root ganglion (DRG) and its distribution in the dorsal horn were investigated after unilateral adjuvant-induced inflammation in the rat paw and compared with CGRP, using in situ hybridization and immunocytochemistry. At 12 h and day 3, but not day 21, the percentage of nerve cell profiles expressing IAPP and CGRP mRNA was greater in the ipsilateral L5 DRG; these changes paralleled the occurrence of edema around the tarsotibial joint and a slight limp. IAPP expression in individual nerve cell profiles was higher in the ipsilateral L5 DRG at 12 h, but not at days 3 and 21; the corresponding CGRP mRNA level was higher at days 3 and 21. At day 3, the higher expression of IAPP and CGRP on the ipsilateral side was accompanied by increased numbers of immunoreactive DRG neurons and fibers in the spinal cord dorsal horn. Largely, expression of IAPP and CGRP seems to be co-ordinately regulated by localized inflammation, although the rapid, but transient, upregulation in DRG neurons of IAPP mRNA expression and the slower, but sustained, upregulation of CGRP mRNA expression may indicate dissociated regulation of the peptides. Thus, IAPP could play a role in the initial phase of localized inflammation.

  • Pituitary adenylate cyclase-activating peptide is upregulated in sensory neurons by inflammation
  • 1998
  • Ingår i: NeuroReport. - 0959-4965. ; 9:12, s. 2833-2836
  • Tidskriftsartikel (refereegranskat)abstract
    • The neuropeptide pituitary adenylate cyclase-activating peptide (PACAP) is expressed in sensory neurons. Expression of several neuropeptides is up-regulated in sensory neurons following inflammation. To examine whether also PACAP expression is regulated by inflammation, PACAP expression in L5 dorsal root ganglion (DRG) was determined, using in situ hybridization, after unilateral adjuvant-induced inflammation in the rat paw. At 12 h and day 3, but not day 21, the percentage of neurons expressing PACAP mRNA was greater in the innervating L5 DRG. Similarly, PACAP mRNA expression in individual neurons was higher in the innervating L5 DRG at 12 h and day 3, but not day 21. Up-regulated PACAP expression following adjuvant injection suggests a role for PACAP in inflammation.
