Outline of Final Research Achievements

In this study, we developed a method for gene knockdown of CACNA1A which is the responsible gene for spinocerebellar ataxia type 6 (SCA6) using CRISPR interference(CRISPRi)technology. We also engineered non-toxic herpes simplex virus-based (HSV) vectors encoding the CACNA1A-CRISPRi expression system. Our results would help develop for non-toxic HSV vector-mediated SCA6 therapy.

Academic Significance and Societal Importance of the Research Achievements

本研究の特色は、これまでに医療応用が難しかったHSVベクターを無毒化することで、CRISPR技術との融合を可能にした点である。HSVベクターは遺伝子治療ベクターとして研究開発されるようになり久しいが、それにも拘わらずその応用範囲が極めて限定的であったのは、その高い細胞障害性が原因であった。申請者らが開発した無毒化HSVベクターは、細胞障害性を完全に排除しているため、安全かつ効率的にCRISPR-Cas9システムを神経細胞に導入することができる。本技術が確立すれば、これまで根治が不可能であった脊髄小脳失調症6型(SCA6)などの神経変性疾患に対する治療技術の有力な選択肢の一つとなり得る。
