Galanin, a 29-amino-acid peptide expressed in dorsal root ganglia (DRG) and spinal dorsal horn interneurones, is regulated by nerve injury and peripheral inflammation. The functional significance of such regulation has been subject to intense studies, including the analysis of galanin null mice, with the production of apparently conflicting results. Here, we suggest that upregulation of galanin in DRG neurones following nerve injury results in antinociception via stimulation of galanin GAL1… CONTINUE READING
