| Outline of Final Research Achievements |
In this study, we focused on sterile inflammation, which is a pathogen-free inflammation that is known to be deeply involved in the induction of tissue damage caused by obesity and type 2 diabetes. The innate immune system, which originally exists to protect us, mistakenly attacks ourselves through sterile inflammation. Autophagy, the intracellular clearance mechanism, suppresses sterile inflammation and prevents the onset of disease. Through analysis of these mechanism, we elucidated the mechanism of induction of renal damage caused by innate inflammation associated with obesity and type 2 diabetes.

慢性腎臓病の有効な治療法はいまだになく、現状では血圧コントロールや血糖コントロール、食事療法などの保存的な治療に頼らざるをえない。本研究では、自然炎症とオートファジーに着目し、①脂肪酸が自然炎症を惹起する機序において、骨髄系細胞内のオートファジーがどの様な役割を演じるのか、②オートファジーによる新たな自然炎症の制御メカニズムを明らかにし、当該機構を標的とする新たな腎臓病治療の開発に資する基盤的研究を推進する。
