Outline of Research at the Start

KIF1Aは神経細胞内の物質輸送を担うモータータンパク質である。KIF1Aの遺伝子変異は運動神経の異常、感覚神経障害、自閉症などの様々な病気の原因となる。KIF1A遺伝子の変異の位置によってこれらの様々な疾患が引き起こされる原因は明らかになっていない。この研究では神経細胞や脳神経の病気のモデル生物として広く用いられている線虫を用いることでこの問いの答えを明らかにする。

Outline of Final Research Achievements

In recent years, as genome sequencing has become easier, mutations in KIF1A have been reported in a number of arcuate congenital neurological diseases. We analyzed KIF1A-associated neurological diseases using single-molecule-level molecular motor motility analysis methods and the nematode Caenorhabditis elegans to elucidate the molecular mechanisms underlying the pathogenesis of these diseases and to gain new insights into the molecular mechanisms of axonal transport.

Academic Significance and Societal Importance of the Research Achievements

軸索輸送は神経機能の維持に重要な役割を持っている。軸索輸送の異常はアルツハイマー病や筋萎縮性側索硬化症などの様々な疾患の原因となっている。また、近年では老化によって軸索輸送の量が減ることが老化による神経機能の低下に関係しているとも言われている。この研究では軸索輸送を担うモータータンパク質の異常が引き起こす疾患について解析を行い、その原因を解明した。本研究の成果は軸索輸送の異常が原因で起こる他の神経疾患のメカニズムの解明にもつながると期待される。
