Outline of Final Research Achievements

Although dogs have remarkable olfactory acuity, their molecular mechanism, which realize the ultra-sensitivity to odorants, have been still unknown. We investigated the extracellular components, which affect on the olfactory sensitivity in the olfactory organ, and developed the vapor odorant detection system using the heterologous gene expression system and the method for electrochemical measurements of aqueous odorants. Functional olfactory receptor gene expression revealed the extracellular component, which sensitize the olfactory response, but not the response to non-volatile molecules. To analyze the molecular mechanism of this sensitization, we developed the vapor odorant stimulation and the response recording system at the single-cell level. We also developed the electrochemical method for the rapid detection of aqueous odo

Academic Significance and Societal Importance of the Research Achievements

近年、イヌなどの様々な動物の嗅覚を用いた病気診断や環境測定の社会的ニーズが急速に増大している。しかし現場では生きた動物が必要となり、普及の足かせになっている。嗅覚の優れたしくみを解析し、それを人工的に再現することは、このような社会的ニーズに応える重要研究目標である。本研究により嗅覚に関わる分子機構の一端が明らかにされたとともに、人工的なセンサー開発に向けた重要基盤要素である、人工的な細胞に気体状匂い刺激を検知させる装置開発が加速することが期待できる。
