Research Abstract

アルツハイマー病(AD)では、アミロイドβ蛋白(Aβ)の脳内蓄積機構の解明が重要な課題となっている。我々は、Angiotenisn-converting enzyme(ACE)が、重合能の強いAβ42を神経保護作用をもつAβ40に変換する活性(Aβ変換活性)を有することを見いだした。更に、Aβ変換活性とアンギオテンシン変換活性がACEの異なるドメインに存在することを明らかにした。
プレセニリン(PS)は家族性ADの主な原因遺伝子であり、γセクレターゼ複合体の中で中心的な役割を担っている。我々はPS 1,2欠損細胞を用いて、プレセニリンが蛋白特異的にtraffickingやmaturationを制御することを明らかにした。
