| Outline of Final Research Achievements |
A novel nanomaterial-based system that could selectively recognize macrophages and effectively remove antibodies in the blood through macrophages was developed. This system consisted of a main body that could target macrophages and a grafted protein that could bind with blood antibodies such as immunoglobulin G. Injection of system into mouse models of experimental autoimmune myocarditis decreased the levels of blood immunoglobulin G compared with those in the phosphate-buffered saline (PBS)-injected group, although this treatment failed to show a statistically significant difference.

| Academic Significance and Societal Importance of the Research Achievements |
装置に頼らない、より簡便で、持ち運びや保存に便利な血中抗体の除去システムは自然災害など免疫吸着療法の実施が困難な緊急時にも使用可能である。患者の生体内に存在するマクロファージに血中抗体を選択的に運んで分解・除去するシステムの開発は非常に独創的な研究であり、心筋炎動物モデルを用いた評価でその可能性を確認したことに大きな意義がある。
