Outline of Final Research Achievements

Free fatty acid receptors play an important role in regulating energy metabolisms and immune systems. In this study, I investigated the function of a novel free fatty acid receptor, GPR164, in maintaining intestinal homeostasis using Caco-2 cells or GPR164 knockout mice. As a result, I reveal that GPR164 is a crucial for the intestinal barrier function. To my knowledge, there are no previous reports described the function of GPR164 using GPR164 knockout mice. Therefore, this study provides new understanding of the physiological functions of GPR164.

Academic Significance and Societal Importance of the Research Achievements

GPR164は機能未知な脂肪酸受容体であることから、腸管バリア機能制御という生体での機能を明らかにできたという点において学術的意義の高い研究であると考える。また、腸は腸管局所だけでなく、全身の生体機能に大きく影響を与えることから、GPR164は様々な生体機能に関与する可能性がある。GPR164はこれまで最も創薬の標的とされてきたGPCRであることから、GPR164と疾患との関りを明らかにすることは、治療標的を提示することに繋がり、社会的意義が大きいと考える。
