Outline of Final Research Achievements

Motor neurons derived from patients with familial ALS are prone to aggregate formation and cell death. As A2a cells,a mouse neuroblastoma cells, into which the mutant SOD1 gene was incorporated, have shown intracellular aggregates and insoluble abnormal proteins, an ALS model cell system has been established. Administration of human deciduous dental pulp stem cell culture supernatant (SHED-CM) was found to suppress the accumulation of insoluble abnormal protein.In addition, ethanol extract components of Brazilian green propolis, as well as its selective components of kaempferol and also α7nAChR, a nicotinic acid receptor, have revealed to activate autophagy and suppress cell death. We have prepared differentiation to motor neurons using iPS cells derived from a patient with SOD1 mutation, a patient with sporadic ALS, and a healthy control.

Academic Significance and Societal Importance of the Research Achievements

筋萎縮性側索硬化症(ALS)はこれまで多くの研究がなされ、モデル細胞やモデル動物を使って多くの創薬が提言されてきたが、ヒトにおいて臨床上満足のいく有効な薬剤は見出されていない。ヒトiPS細胞を使った研究は新たな創薬への道を切り開いている。ALSの病態は複数の要因が多面的に作用しており、単一薬剤での十分な有効性は得がたい。SHED-CMは多くの有効成分を含み、自然が作りだした複合剤で、神経難病への活用に期待が大きい。SHED-CMの有効性についてN2a細胞モデル系を使って証明し、作用機序、有効成分について検索した。ALS患者由来のiPS細胞についても準備し、創薬スクリーニング系を立ち上げた。
