| Outline of Final Research Achievements |
To study the mechanism of generation of neuropathic pain, a role of adenosine-triphosphate (ATP) on a novel heat-activated K+ channel (Kheat) in dorsal root ganglion neurons of the rat was examined using a patch-clamp technique. Kheat was isolated by Ba2+ or tetraethylammonium. Under the isolation of Kheat, ATP did not affect to Kheat, as well as to TRPV1 receptors.
The reason of the less effect of ATP might be attribute to using normal rats but not neuropathic pain model rats in this study. To clear the problem, similar experiments will be continue in neuropathic pain model rats.
