Outline of Final Research Achievements

In this study, we have worked on the development of a biosensor using cells with hTAS2R in order to bring it closer to the human taste receptor response.
Plasmid vectors with TAS2R10 and TAS2R14 gene sequences as hTAS2R were transfected into HEK293 cells, and stable cultured cells were established. Polyvinyl chloride, an existing polymer support, was used as the base of the sensor chip of taste sensor, and a support containing iron oxide was fabricated to enhance the conductivity of the support.

Academic Significance and Societal Importance of the Research Achievements

苦味物質によっては従来の味覚センサと反応しにくい物質も存在するため、ヒト官能試験の実施が不可欠であり、その試験結果と味覚センサの測定結果との相関性を考慮することが必要である。しかし、倫理的な観点から、ヒト官能試験を行うことのできない医薬品や新規開発医薬品などが存在するため、新規バイオセンサはヒト官能試験の代替法としても利用可能である。
