Outline of Final Research Achievements

The roles of fractalkine (FKN) on rheumatoid arthritis was analyzed. FKN did not alter production of inflammatory cytokines by peripheral blood monocytes. FKN upregulated osteoclast differentiation from peripheral blood CD16- monocytes. Furthermore, FKN upregulated osteoclast formation from dendritic cells derived from peripheral blood CD16- monocytes. These results suggest that FKN might have roles of not only inflammatory cell accumulation, but also bone destruction, on rheumatoid arthritis.

Academic Significance and Societal Importance of the Research Achievements

現在、抗フラクタルカイン(FKN)抗体による関節リウマチに対する治験が行われている。本研究結果は関節リウマチにおけるFKNの作用の一つを明らかにしたものであり、今後、抗FKN抗体が関節リウマチに使用できるようになった際には、その期待できる治療効果を予測したり、また適応患者の選択にも役立つ。
