| Outline of Final Research Achievements |
Rheumatoid arthritis (RA) is a disease that requires assistance and nursing care due to chronic inflammation caused by autoantigens that lead to joint destruction. The problem is that there are patients who are refractory to RA treatment and patients who are forced to undergo treatment with expensive medication and suffer from financial anxiety, so it is important to prevent the disease in the long term from the onset stage. In this study, we selected a pre-stage group with RA risk factors from participants in a health checkup and identified a molecule specific to this pre-stage group. We then found that this molecule increases as RA progresses, indicating that it could be a future therapeutic target.

長崎大学が実施する離島健康診断の参加者には「未病の関節リウマチ予備群」が含まれるというユニークな発想を起点に、未病期から進行に応じて増加する分子を特定した。関節リウマチの治療は抗体医薬で進歩したが、長期の治療では高額な医療費が必要となり、抗体医薬を使う患者のほぼ全員に経済的不安があるとされる。今回の研究で特定した分子は、未病期からの予防治療に適した薬のデザインに欠かせない情報であり、現在の治療に不応でQOLが低下する不安や経済的不安を抱える将来の患者に向けた新たな予防戦略を立てる研究に発展する。
