Outline of Final Research Achievements

Idiopathic pulmonary fibrosis is defined as progressive interstitial pneumonia with poor prognosis. However, the mechanism of it remains unclear. Angiopoietin-like protein 2 (Angptl2) is a chronic inflammatory mediator, which when deregulated is associated with various pathologies. However, little was known about its potential lung function. To examine the role of Angptl2 for lung function, we generated a rabbit monoclonal antibody that specifically recognizes mouse Angptl2 and then evaluated protein expression in mouse lung tissue. We observed abundant Angptl2 expression in both alveolar epithelial type I and type II cells and in alveolar macrophages under normal conditions. Next, we examined Angptl2 lung function in a mouse interstitial pneumonia model and found that Angptl2 deficiency made fibrosis caused by bleomycin exacerbated fibrosis. Overall, our findings suggest that Angptl2 expression in lung epithelial cells may function in repair of damaged tissue.
