◆新しいアプローチはセリアナノ粒子(Ce NPs)と幹細胞由来のナノ小胞(MSCNVs)を組み合わせたもので、これらの成分は炎症の即時の緩和と免疫の修復を実現し、症状の再発を防ぐことを目指しています。
◆マウスモデルでの実験で、Ce-MSCNVシステムはRAの包括的な治療と予防に成功し、一回の投与で改善が見られたと報告されています。このアプローチは、効果的なRA治療法の開発に寄与する可能性があります。

Abstract
Commencing with the breakdown of immune tolerance, multiple pathogenic factors, including synovial inflammation and harmful cytokines, are conjointly involved in the progression of rheumatoid arthritis. Intervening to mitigate some of these factors can bring a short-term therapeutic effect, but other unresolved factors will continue to aggravate the disease. Here we developed a ceria nanoparticle-immobilized mesenchymal stem cell nanovesicle hybrid system to address multiple factors in rheumatoid arthritis. Each component of this nanohybrid works individually and also synergistically, resulting in comprehensive treatment. Alleviation of inflammation and modulation of the tissue environment into an immunotolerant-favourable state are combined to recover the immune system by bridging innate and adaptive immunity. The therapy is shown to successfully treat and prevent rheumatoid arthritis by relieving the main symptoms and also by restoring the immune system through the induction of regulatory T cells in a mouse model of collagen-induced arthritis.
