| Outline of Final Research Achievements |
The aim of this study was to investigate the effect of quercetin on the neuropathic pain in the rat model. Pre-treatment of neuropathic pain by oral administrated quercetin prevented the development of pain behavior in the rat with spared nerve injury model. On the other hand, post-treatment failed to reverse the pain behavior. Immunohistochemisty and western blotting showed significant suppression of GFAP protein, a marker of astrocyte activation, in dorsal root ganglion in the treated rats. These results showed that the effect of quercetin on the neuropathic pain was mediated by the suppression of activation of satellite glial cells in dorsal root ganglia.
