| Outline of Final Research Achievements |
On the state of neuropathic pain, histamine-evoked pain-sensation, which is mediated through the direct activation of polyamine-recognition site of NMDA receptor in spinal cord by histamine, is enhanced. On the other hand, the super-sensitivity of TRPV1 receptor on the planter skin of paw was revealed to induce the neuropathic pain. The results of this project suggest that the spinal polyamine-recognition site of NMDA receptor and TRPV1 receptor on the skin may be key targets to develop the new therapy for neuropathic pain.
