Keywords関節リウマチ / 抗シトルリン化タンパク質抗体 / N-結合型糖鎖 / 破骨細胞 / モノクローナルACPA
Outline of Research at the Start

関節リウマチは、成人人口の0.5-1%が罹患し、主に30-50歳代の働き盛りの女性に多く見られる。関節リウマチには、特徴的な自己抗体が見つかっており、この自己抗体が関節リウマチの原因と考えられている。しかしながら、自己抗体と関節リウマチ発症の因果関係は未だ不明である。本研究は、この自己抗体と関節リウマチ発症の因果関係を明らかにすることを目的とする。この成果により、明らかにした機序に基づいた新しい治療法、予防法の開発に繋がることが期待される。

Outline of Final Research Achievements

The variable region of most ACPA IgG molecules in the serum of RA patients carries N-glycan Nevertheless, important issues on the effects of N-glycan on the pathological function of soluble ACPAs in RA are still unclear. The present study showed a monoclonal ACPA, CCP-Ab1, derived from the peripheral blood B-cells of patient with RA promoted osteoclast differentiation, enhanced bone resorption capacity and augmented the exacerbation of experimental arthritis in SKG mice. This insight provides clues to how ACPAs are related to the onset and exacerbation of RA. The inhibition of osteoclast-induced signalling by N-glycans is expected to lead to the development ofnew therapeutic agents for RA.

Academic Significance and Societal Importance of the Research Achievements

ACPA-IgG可変領域のN-結合型糖鎖の新しい意義として、リウマチ学における新たな研究領域の形成に繋がることが期待される。さらに、RAの病因とAPCAによる病態メカニズムの関係を研究する上で重要な結果の一つになり、関連する基礎・臨床医学の発展に寄与することが期待される。また、 ACPAにより破骨細胞への分化を促進するシグナル伝達を対象としたRAの新たな予防や診断、治療の研究への発展に繋がることが期待される。
