Outline of Final Research Achievements

Aberrant production of the anti-neutrophil cytosolic autoantibody (ANCA) causes the ANCA related vasculitis (AAV). To analyze the previously identified QTL on chromosome 1 for production of ANCA, we introduced the QTL to B6/lpr and proved the pathogenic function of the QTL (Autoimmunity 52:208, 2019). We identified two candidate genes for abnormal production of ANCA using the next generation sequencer. One was the structual gene for a proteinase inhibitor and it had non-synonymous polymorphisms. We produced recombinant proteins of wild and variant types to analyze their fuctional changes. Another one was the gene coding membrane surface protein on peripheral blood mononuclear cells.
We are going to develop these items into the medication experiment to animal individuals, and the surface character analysis of PBMC in a human AAV case. The results can possibly be the seeds for the development of therapautic medicines.

Academic Significance and Societal Importance of the Research Achievements

本研究により得たタンパク、遺伝子欠損マウスを用いて、活性化顆粒球やNETsによる細胞傷害試験への影響、AAVモデルマウスへの治療的投与実験が可能となった。
折しも、新型コロナウイルス感染がパンデミックとなっており、感染者の急速かつ重篤な全身炎症が広く報告されている。この遺伝子が持つタンパク分解酵素阻害活性は、治療薬開発の糸口となる可能性がある。これらを発展させ、リード薬作製へつなげていきたい。
