Outline of Final Research Achievements

Elucidation of the contribution of the NLRP3 inflammasome to arteriosclerosis using a model mouse created by our laboratory that has an existing genetic mutation inserted into Muckle-Wells syndrome, one of the diseases in which the inflammasome is constantly activated. The goal was to Stimulation of splenocytes with LPS resulted in higher IL-1β release compared to wild-type mice. I confirmed that there is These mice were used to obtain phenotypic transitions, blood, and histological samples over a long period of time from the fetal period to 12 months of age. We found that hemodynamics and cardiac morphology changed dramatically in the long-term course.

Academic Significance and Societal Importance of the Research Achievements

心血管疾患、特に動脈硬化症やうっ血性心不全は高齢化社会において克服すべき大きな課題である。これらの疾患の病態には慢性炎症が関与している。炎症抑制、特にIL-1βを抑制することで心血管イベントの二次予防になることが大規模臨床研究で統計学的に明らかになり、IL-1βが治療標的と考えられるようになった。しかしながらIL-1βは多様な免疫応答の要であり阻害による免疫抑制はリンパ増殖性疾患などの原因となりうる。NLRP3インフラマソームの動脈硬化症への寄与が明らかとなれば、NLRP3インフラマソームのみを標的とした分子標的治療が可能となり、副作用のないプレシジョンメディスンが実現する。
