| Outline of Final Research Achievements |
We determined the effects of nicotinic acetylcholine receptor (nAChR) signaling on regulation of macrophage phenotypes that contribute to chronic inflammatory disease such as neuropathic pain. Macrophages underlying neuropathic pain express nAChR, and nAChR ligands suppressed the production of inflammatory mediators in vivo and in vitro. Moreover, it is important that administration of nAChR ligands improved neuropathic pain. In conclusion, regulation of inflammatory macrophages through nAChR signaling may be effective pharmacotherapy for the relief of chronic inflammatory diseases.
