Outline of Research at the Start

網膜疾患に対する再生医療は、社会的にも学術的にも大きな期待が寄せられているが、中枢神経系である網膜は、複雑な回路の形成過程や可塑的性質を有し、構造的にも機能的にも再生は容易ではない。網膜再生技術の確立には、正常・病変・再生網膜のいずれに対しても機能・機能不全の仕組みを明らかにし、網膜の設計図となる構成論的理解が必要不可欠である。本研究は、網膜回路動態の神経科学的解析および網膜再生技術の開発と連携し、網膜回路特有の動的特性が実現する情報処理機構および機能構築に関する数理モデルの構築を目指す研究である。

Outline of Final Research Achievements

Retinitis pigmentosa is a representative disease of the retina, which eventually leads to blindness. The therapy of this disease has not yet been developed. Regenerative medicine and other therapies have been being developed, but their effectiveness depends on the condition of the patient's retina. Studies on animal models of the disease have shown that abnormal autonomic neural activity is observed in the diseased retina. In order to understand the patient retinal condition, we clarified the mechanism of the abnormal autonomic neural activity by which the diseased neural activity occurs by means of electro-physiological experiments, histological analysis, and mathematical model simulations.

Academic Significance and Societal Importance of the Research Achievements

網膜色素変性症の治療には、その疾患により脱落する視細胞を再生技術により再生した視細胞の移植により補填することが試みられているが、その効果は視細胞の下流にあたる網膜神経の状態に依存する。本研究により、2次変性部位と病変神経活動の原因がその変性であることを明らかにできたので、治療のターゲットを同定できることにより、より確実な治療法の開発に寄与すると期待できる。
