Outline of Final Research Achievements |
To clarify the involvement of long-chain fatty acid receptor (GPR40/FFAR1) in stress-induced chronic pain, we aimed to generate mice with selective GPR40/FFAR1 knockout in intestinal epithelial cells. First, GPR40-Floxed/Neo(+) were mated with Actb-FLp mice to delete neomycin. And then, C57BL6N mice were mated with GPR40-Floxed/Neo (-)FLP(+) mice to generate GPR40-Floxed/Neo (-)FLP(-) mice. GPR40-Floxed/Neo (-)FLP(-) mice were crossed with Vil1 Cre/ERT mice, which express Cre recombinase and mutant estrogen receptor (ERT) in intestinal epithelial cells. Finally, we got intestinal epithelial cell-specific GPR40/FFAR1-deficient mice.

Academic Significance and Societal Importance of the Research Achievements |
本研究は、腸管上皮細胞特異的に GPR40/FFAR1 を欠損させたGPR40CKOマウスの作製に成功した。本マウスは、腸管GPR40/FFAR1の新たな役割の発見やその生理学的意義の解明に貢献できるため、その社会的意義は大きい。さらに、GPR40-Floxed マウスと他のCreドライバーマウスを交配させることで、様々な組織におけるGPR40/FFAR1をノックダウンまたはノックインできる。本研究成果は、新たなGPR40/FFAR1の生理作用の解明につながることが期待される。
