Outline of Final Research Achievements

Using genome-edited rats, we determined the origin of intimal smooth muscle cells in pulmonary vascular lesions of PAH and elucidated whether CCR2 is essential for the formation of intimal lesions in PAH in vivo.(A) Effect of PAH on pulmonary vascular lesions in CCR2 knock-out rats: Hemodynamics was evaluated by echocardiography and cardiac catheterization, and hemodynamic and tissue lesions were improved in knock-out rats. (B) Fate mapping analysis of differentiated smooth muscle cells in a PAH model using Myh11-Cre rats: We have now succeeded in generating Myh11-Cre-ERT2 knock-in rats using genome editing technology.

Academic Significance and Societal Importance of the Research Achievements

CCR2を介した炎症がラット肺高血圧の肺血管病変の発症、進展に必須であることが判明した。これにより、肺高血圧の病変形成の機序の解明における、CCR2を介した経路の解明につながる。さらに、CCR2ないしその下流の重要な経路を標的とする分子標的治療の可能性を開く。さらに肺高血圧の閉塞性肺血管病変の血管平滑筋由来の細胞の関与が明らかになれば、その分化、遊走が内膜肥厚の形成に繋がるか否かの検討が初めて可能となる。それを踏まえて、内膜形成における分子標的治療の開発への可能性が広がる。
