Outline of Final Research Achievements

We have identified the mutation in NLRC4 as the causative mutation of familial cold autoinflammatory syndorome. The mutation increased the pyroptosis of cells, which is associated with the increased cytokine secretion leading to the inflammation. We also identified the causative gene of familial pulmonary fibrosis and the mutation increased the cell death of type 2 alveolar epithelial cells. The Notch signaling controls the expression of Atp8a2 that has flippase activity. The Notch-mediated expression of Atp8a2 helps the escape of intraepithelial lymphocytes in the small intestine from the engulfment of macrophages.

Academic Significance and Societal Importance of the Research Achievements

細胞死の機能異常が関わる遺伝性疾患の原因遺伝子を同定することに成功し、その解析から各種の細胞死の機能異常が重篤な炎症病態を引き起こしうることが明らかになった。その成果から、重篤な炎症性疾患の治療標的として細胞死の分子経路が該当すると考えられ、今回の研究成果は創薬開発にとって極めて重要な知見をもたらしたと考えられる。
