Outline of Research at the Start

ヒドロキシプロピルメチルセルロース(HPMC)は、薬剤のカプセルや糖衣、食品添加物とし
て広く、長く用いられている。プリオン感染モデルマウスにおいて、非常に顕著な延命効果をもたらすことを見出した。また、ワクチンのように単回投与で長期間の予防効果が得られる。これまでの研究から貪食性の細胞の関与を示すデータが得られている。生体内での細胞の状態を穏やかに変化させることにより、プリオン感染を防止する作用は、発症時期とリスクの予想が困難なプリオン病の予防薬として理想的である。プリオン感染モデルマウスにおいて治療・予防の根拠となる因子を明らかできれば、蛋白質異常沈着を伴う他疾患の治療の芽ばえとなる。

Outline of Final Research Achievements

We have found that cellulose ether, which is routinely ingested as a capsule and thickener for pharmaceuticals, has significant anti-prion activity in mice. In this study, we investigated what biological functions are involved in this unexpected effect. Investigations of brain proteins have identified a protein called glial maturation factor b, and investigations of cell types have identified several receptors on T cells as relevant candidates for the anti-prion activity.

Academic Significance and Societal Importance of the Research Achievements

プリオン病をはじめとする神経変性疾患の実効的な治療手段が求められている。セルロースエーテルは、本来、生体不活性な化合物として日常生活に広く用いられているうえ、幾つかの特性は、プリオン病のような特殊な疾患に適している。抗プリオン活性に関与する応答などが見つかられは、プリオン病とはじめとする神経変性疾患に対抗する手段を提供できることとなる。
