| Outline of Final Research Achievements |
This study was performed to reveal mechanisms of spinal itch transmission using in vivo electrophysiological, pharmacological and behavior methods. We found that SP, GRP, and glutamate each partially contribute to histamine-independent itch, whereas histamine-evoked itch is mediated primarily by glutamate. Co-application of NK-1, GRP, and AMPA receptor antagonists may prove beneficial in treating chronic and intractable itch such as atopic dermatitis. We are currently trying to investigate antipruritic therapeutic effects in chronic itch models such as dry skin and atopic dermatitis.
