| Outline of Final Research Achievements |
Although there are many nutritional metabolites with preventive effects on lifestyle-related diseases, the molecular mechanism has yet to be elucidated. In this study, we aimed to identify new molecular targets for orphan nutritional metabolites by utilizing our unique assay of transporter. We identified several nutritional metabolites that strongly inhibit a vesicular nucleotide transporter to control purinergic chemical transmission. The nutritional metabolites showed preventive and therapeutic effects on lifestyle-related diseases by selectively blocking the vesicular ATP release. We propose a new preventive care of lifestyle-related diseases by blocking purinergic chemical transmission.

| Academic Significance and Societal Importance of the Research Achievements |
生活習慣病は日本で2000万人の罹患者・予備軍がいるにも関わらず、副作用の少ない、有効な予防・治療薬がない。プリン作動性化学伝達は、慢性疼痛、糖尿病、脂質異常症、潰瘍性大腸炎、非アルコール性脂肪肝炎、アトピー性皮膚炎、アルツハイマー病、パーキンソン病等の難治性疾患の発症に関与している。そのため、本研究で得た知見は、オーファン栄養代謝物の分子標的の同定という学術的意義に加えて、生活習慣に起因する幅広い難治性疾患に対して、副作用が少なく、有効な予防法の確立に寄与するものである。
