Research Abstract

研究成果の概要:麻薬性鎮痛薬であるオキシコドンは、特殊なトランスポーター(運び屋タンパク質)によって脳内へ運ばれ、鎮痛作用を発揮することが示された。このトランスポーター分子を探索したところ、血液と脳の間の関門に、新たなトランスポーターを発見した。このトランスポーターは薬物のみでなく、セロトニンなどの神経伝達物質を脳から血液に汲み出すことにより、脳内の神経伝達物質の濃度を調節すると考えられた。研究成果の概要:麻薬性鎮痛薬であるオキシコドンは、特殊なトランスポーター(運び屋タンパク質)によって脳内へ運ばれ、鎮痛作用を発揮することが示された。このトランスポーター分子を探索したところ、血液と脳の間の関門に、新たなトランスポーターを発見した。このトランスポーターは薬物のみでなく、セロトニンなどの神経伝達物質を脳から血液に汲み出すことにより、脳内の神経伝達物質の濃度を調節すると考えられた。
