Outline of Research at the Start

自己免疫疾患の診断には特異的な自己抗体の検出が有用である一方で、自己抗体自身の臓器病変への影響は不明なままである。本研究では、シェーグレン症候群をはじめ自己免疫疾患のモデル動物を用いて自己抗体の病原性に関する詳細な検討を加えることにより、自己反応性B細胞ならびに自己抗体を基盤とした自己免疫病変への新たな病因を探索する。診断への応用が中心であった自己抗体を起点として、病態制御の可能性を探ることは新たな治療法に向けての重要な内容と言える。さらに、本研究は、自己抗体の過剰産生機構を応用したワクチン開発、アレルギー疾患など多角的な臨床応用が可能になる。

Outline of Final Research Achievements

We focused on the pulmonary lesions in a mouse model of Sjogren’s syndrome in which B cells related to autoantibody production were accumulated unlike the salivary gland lesions. Anti-CD4 mAb, but not anti-CD19 mAb, could regulate the inflammatory lesions of the lung in SS model mice. In addition, CD23+B cells were mainly infiltrated in the pulmonary lesions (Front Immunol 2023). Furthermore, the early B cell differentiation was impaired in the bone marrow tissue of SS model mice, suggesting that autoreactive or abnormal B cells may exist in the bone marrow (in preparation for publication).

Academic Significance and Societal Importance of the Research Achievements

自己免疫疾患における血清中の自己抗体の検出は診断のマーカーとして極めて重要であることはよく知られている一方で、その詳細な産生機構あるいは病原性に関しては不明な点が多い。シェーグレン症候群の自己抗体として抗SS-Aあるいは抗SS-B抗体が知られているが、病態との関連性はよく分かっていない。本研究では、骨髄での初期B細胞分化の異常ならびに末梢でのCD4+T細胞とCD23+B細胞の相互作用を介した自己抗体に関連した自己免疫病変の形成機序が存在することが示された。本研究の成果は自己免疫疾患のB細胞を介した新たな発症機序の解明と臨床応用へつながる可能性が示された。
