Outline of Research at the Start

本研究では、CHS患者由来iPS細胞から分化させた神経細胞を用い、LYST変異により形成された異常ミトコンドリア、異常オートファゴソームが、リソソームへの輸送障害、リソソーム機能低下、オートファジー機能低下により処理できず、神経細胞内に異常な細胞内小器官および細胞代謝物(老廃物)が蓄積し、神経変性に陥るという仮説を証明し、CHSにおける神経変性疾患発症の病態解明さらに治療薬開発につなげる。

Outline of Annual Research Achievements

Chediak東症候群(CHS)は神経変性および免疫不全を呈する疾患である。原因遺伝子はLYSTであるが、神経変性の発症機序は不明である。本研究ではChediak東症候群(CHS)患者6症例からiPS細胞を樹立し、神経細胞に分化させ細胞内小器官の解析を行なった。6症例のLYST遺伝子変異は全て異なり、5症例で神経症状があり1例は幼児のため神経症状は判定不能であった。
患者由来iPS細胞から分化誘導した神経細胞の解析で、リソソームの巨大化、PAS染色陽性物の沈着などの形態異常を認め、機能解析でカルシウム依存性エキソサイトーシス障害を認めた。ミトコンドリアは、電子顕微鏡の解析で、巨大化、不整化などの形態異常を認めた。また核周囲への局在化、分布異常も認めた。オートファゴソームは、DAP Green染色による蛍光顕微鏡の解析で、輝度が亢進した異常オートファゴソームの著明な増加を認めた。以上、Chediak東症候群(CHS)の神経細胞では細胞内小器官の異常があることを明らかにした。
このことから、CHSの神経細胞ではLYST変異により異常ミトコンドリア、異常オートファゴソームが形成され、リソソームの処理機能低下やオートファジー機能低下により、異常な細胞内小器官や細胞代謝物(老廃物)が細胞内に沈着し、神経変性の原因となっていると考えられた。
予定していた研究内容を実施することができた。
