Keywords網膜色素変性 / リモデリング / トランスジェニックウサギ / 自己網膜パッチ
Outline of Annual Research Achievements

視覚再生の対象の一つである、網膜色素変性の中型モデルである、我々の開発したTgウサギにおける残存神経機能の評価において、ヒトでも可能なEEPで示される電気生理学的値に比較し、解剖で得られた軸索の数は、それ以上に残存していることがわかり、末期の残存神経機能は想定以上に賦活化される可能性があることを見出した。
さらに、我々はこれまで、3年までのP347L Tgウサギについては、組織学的な変化を報告しているが、さらに5年の長期観察により、より進行した網膜色素変性患者の網膜変化を動物モデルで捉えることができたと考えた。すなわち、TgウサギのERGの振幅は徐々に減少し、30~54ヶ月の間に10μVに達した。長期間経過後の組織学的分析では、視細胞は消失していたわけだが、しかしながら、内境界膜とouter plexiformとの間の厚さは、WTウサギの厚さよりも約1.7倍厚かった。この肥厚は、顕著なグリオ-シスによって引き起こされたことがlight transmission microscopeでわかった。さらに、immunohistochemicalな解析では、高齢のP347L Tgウサギにはglial fibrillary acid proteinの過剰な染色があったが、杆体ONバイポーラ細胞および水平細胞は依然として内部核層に存在していた。以上のように、進行した末期の網膜色素変性であっても依然として視覚再生の道は開ける可能性があると判断した。
巨大な黄斑円孔に対して他院で行われた自己網膜パッチに対し、微小黄斑局所ERGや機能検査、SS-OCTなどを行い、良好な視機能の発生する期限について調べ、発表準備中である。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

動物実験により自己網膜パッチを計画していたが、シリコーンオイル抜去後網膜剥離が発生してパッチの状態を調べることができなかった。

Strategy for Future Research Activity

自己網膜パッチの視機能に関する論文を仕上げる。当院で行われた5例の自己網膜パッチ症例の長期経過についてまとめて、論文とする。
家兎において、自己網膜パッチの移植手術を成功させてcomputational molecular phenotypingを用いた細胞構成の観察を行う。

Causes of Carryover

動物実験の成果がまだ出ていないため、海外の学会での発表の準備ができていないので、海外旅費に使わなかった。
次年度成果が出れば、学会旅費(海外も含む)、投稿準備、論文掲載料として使用予定である。
