Outline of Research at the Start

遺伝子変異によってPyrin蛋白に構造変化をもつ家族性地中海熱(FMF)患者において、Pyrinインフラマソームが直接活性化され、炎症が生じていることが近年証明された。Pyrin蛋白をコードする遺伝子MEFVのエクソン2は、Pyrinインフラマソームの活性化に大変重要な部位であり、多くの遺伝子多型が存在する。本研究では、Pyrinインフラマソームの活性化機構を解明するために、特に本邦に多いMEFVエクソン2変異の意義を検討する。さらに、Pyrinインフラマソームの活性化後に誘導される下流の分子を同定することで、Pyrinインフラマソーム活性化後の慢性炎症の機序を解明したい。

Outline of Final Research Achievements

We analyzed the activation mechanism of the Pyrin inflammasome, which is important for the pathophysiology of familial Mediterranean fever (FMF), and the significance of the MEFV exon 2 variant E148Q, which is especially common in Japan. First, we established the iPS cells derived from the first PAAND (pyrin-associated autoinflammation with neutrophic dermatosis) patient in Japan and were able to differentiate into neutrophils, but we could not secure a sufficient number. In the clinical picture of patients with fever of unknown origin and analysis of gene variants, the compound heterozygotes group containing the E148Q variant had a significantly higher FMF diagnosis rate than the E148Q variant heterozygotes group. It was suggested that the E148Q variant acts as a modifier of other risk alleles by adding other MEFV variants to the E148Q variant, lowers the threshold for disease susceptibility, and contributes to the onset of FMF.

Academic Significance and Societal Importance of the Research Achievements

本邦初のPAAND患者由来のiPS細胞を樹立(細胞バンク登録)できたことは、今後のPyrinインフラマソーム解析に役立つツールとなると考えられる。本邦に多いMEFVエクソン2変異の解釈として、E148Q変異が疾患感受性に対する閾値を低下させ、FMF発症に寄与する可能性が示唆されたことは、学術的にも意義がある。本邦で臨床的にも変異の解釈で問題となっているE148Q変異への考え方に一石を投じたと思われる。
