There is currently some debate over a possible role of galanin in pain processing. It was recently reported that the levels of galanin in dorsal root ganglia (DRGs) seem related to development of allodynia after unilateral sciatic nerve constriction injury. In our present study, we aimed at characterizing the effect of exogenous and endogenous galanin on pain behavior in allodynic and non-allodynic rats in which the levels of galanin in DRG neurons are low and high, respectively [28]. The results show that in allodynic rats, the mechanical threshold increases dose-dependently after intrathecal (i.t.) injection of galanin, while no significant changes were observed in groups treated with the putative galanin antagonist M35 or saline. In non-allodynic rats i.t. injection of M35 induced a significant mechanical allodynic state, which did not occur after injection of galanin, bradykinin, the bradykinin fragment(2-9) or saline. The results suggest that in the present experimental paradigm exogenous galanin has an anti-allodynic effect in the allodynic rats, and that endogenous galanin has a tonic inhibitory effect in the non-allodynic group.
