Outline of Final Research Achievements |
Resolvins are products of ω-3 fatty acids with potent anti-inflammatory properties. ResolvinE3 (RvE3) is a newly identified anti-inflammatory lipid mediator. We also investigated the role of RvE3 in a murine model of HDM-induced airway inflammation. We created RvE3 derivatives and analyzed its effect at the cellular level. We designed and synthesized RvE3 derivatives as oxidatively stable congeners to avoid the unstable bisallylic structure. They suppressed the production of IL-23 from bone marrow derived dendritic cells and suppressed the production of TGF-TGF-β from monocyte. These findings suggest that RvE3 derivatives may be key substituents for the potent anti-inflammatory effect.

Academic Significance and Societal Importance of the Research Achievements |
RvE3は炎症収束の効果が期待できる内在性の炎症収束物質であり、副作用が少なく、安全性が高い、これまでにない新しい創薬研究につながると期待できる。本研究は、生体が本来持つ恒常性維持機能を利用して炎症を制御するという特異なアプローチであり、学術的独自性がある。さらに、RvE3の臨床応用への障壁であった生体内での不安定性を改善した誘導体を作製しており、これらを用いた細胞レベルでの解析の結果、抗炎症性作用を確認できたことは、創薬の対象として検討できる可能性があると考えている。
