Outline of Final Research Achievements

To clarify the transmission mechanism of acute itch and chronic itch, we analyzed the neural network that transmits itch connecting the spinal cord and the brain focusing on the spinal cord and brainstem, which are important relay points of the sensory nervous system in itch hypersensitive model animals. Our study revealed that the change of the itch sensitivity alters the patterns of itch transmission in the gastrin-releasing peptide system of the spinal sensory system and itch transmission was regulated by not only afferent pathway but also efferent pathway.

Academic Significance and Societal Importance of the Research Achievements

慢性化した痒みは日常生活に支障を与えるのみでなく精神面にも大きな影響を与えるが、これまでの痒み研究は皮膚を中心に解明が進んでおり、皮膚から知覚神経系を介した脳へ痒みを伝達する神経ネットワークには不明な点が多い。痒み高感受性モデル動物における知覚神経系の痒み伝達様式の変化と脊髄と脳の痒み伝達クロストーク解析から、今後の痒み伝達機構の解明および治療につながることが期待される。
