Research Abstract

AMPA受容体は興奮性シナプス伝達ならびに学習・記憶の細胞モデルであるシナプス伝達長期増強現象 (LTP) 発現に最も重要なイオンチャネル型グルタミン酸受容体の一つである。LTP発現の一要因としてAMPA受容体traffickingが注目されているが、その作用機序の詳細は不明である。本研究はAMPA受容体traffickingにおけるO-GlcNAc化の役割解明を目的とした。O-GlcNAc化はAMPA受容体の細胞膜表面への特異輸送ガイダンスシグナルとして働き、AMPA受容体エンドサイトーシスを阻害することによって細胞膜表面AMPA受容体数を増加させた。この作用はLTP維持に重要であることが示唆された。
