Research Abstract

パーキンソン病はアルツハイマー病に次いで頻度の高い神経変性疾患であり、根本的治療がなく、高齢化社会に伴い大きな問題になっている。我々は、その機序を解明するため、家族性のパーキンソン病の原因遺伝子でもあり、弧発型パーキンソン病のレビー小体にも存在するアルファ・シヌクレインをウイルスペクターにより黒質神経細胞に過剰発現させ片側パーキンソン病モデルラットを作製し解析した。その結果、黒質神経細胞死の原因としてリン酸化がkeyであることをすでに明らかにしている。この病理像は、パーキンソン病剖検脳では確認されているが、アルファ・シヌクレインTgマウスはその発現量が少ないため細胞死はほとんど生じず、リン酸化も黒質では認めていない。このモデルラットを用いて、リン酸化アルファ・シヌクレインを制御する薬剤をスクリーニングする。スクリーニングに、リン酸化制御薬剤に加えアルファ・シヌクレインのリボザイムを用いて、その効果を判定した。アルファ・シヌクレインのリボザイムをアデノ随伴ウイルスベクターに搭載し投与し、パーキンソン病モデルマウスにて治療効果を確認し報告した(Hayashita-Kinoh H et al. BBRC 2007)。これは、アルファ・シヌクレインを制御することが治療薬になることを示した。これを対照として、その他の薬剤の治療効果について現在も効果判定を続けている。
またこの方法を用いるとパーキンソン病猿のモデルを作成することが可能になる。我々は、大型動物でパーキンソンI病の新規薬剤の治療効果が判定できることを報告した(Yasuda T et al. Neuroscience 2007)。これは、人への安全性を検討する上で非常に学術的に優れた方法である(722字)。
