| Research Abstract |
(1) In this study, we examined the mechanism of neuropathic pain in spinal cord and brain. Especially, we demonstrated how the muscarinic receptors in spinal cord and brain involve in neuropathic pain. Activation of spinal muscarinic M_1, receptors produces analgesic effect to nociceptive stimulation and, at least in part, through neuronal pathways involving spinal GABA_A receptors. In addition, Activation of muscarinic M_1 receptors in the the cinglate cortex attenuated the neuropathic pain and the analgesic effect was mediated by both GABA_A and GABA_B receptors. (2) In addition, we examined the functional role of chemokines in neuropathic pain. Pre-administrations of microglia inhibitor minocycline inhibited the allodynia. This result supports that Chemotactic Cytokine Ligand (CCL)-1 in the spinal cord contributes to the development of neuropathic pain.
