Research Abstract

モルヒネやフェンタネストなどのオピオイドと吸入麻酔薬の相互作用は不明である。アフリカツメガエル卵母細胞発現系を利用し、オピオイド受容体に対する麻酔薬の作用を電気生理学的に解析した。現在までの検討で、これらのGq/GiキメラG蛋白結合μオピオイド受容体の高率の発現を示し、麻酔薬ハロセンなどはμオピオイド受容体に影響することを明らかにした。現在までハロセンは多くのG蛋白結合受容体をリン酸化酵素プロテインキナーゼC(PKC)によって抑制することが報告されているため、μオピオイド受容体の機能にも燐酸化酵素によって影響があるかどうか検討している。これらの結果をもとにμオピオイド受容体への麻酔薬の作用の全貌を明らかにしたいと考えている。
