| Outline of Final Research Achievements |
We created a mouse model (PAOV model) in which left pneumonectomy increased pulmonary blood flow in the remaining right pulmonary artery, causing quantitative volume loading (high flow) in the right pulmonary artery. The left pneumonectomy increased pulmonary blood flow in the remaining right pulmonary artery, causing a quantitative volume load in the right pulmonary artery (PAOV model). This model represents vascular remodeling in the absence of thrombus due to the concentration of blood flow in the right lung. In this model, vascular remodeling was found to occur, and the involvement of macrophages in the mechanism was clarified. These results were presented in a paper.
