Abstract
Exaggerated levels of VEGF (vascular endothelial growth factor) are present in persons with asthma, but the role(s) of VEGF in normal and asthmatic lungs has not been defined. We generated lung-targeted VEGF165 transgenic mice and evaluated the role of VEGF in T-helper type 2 cell (TH2)-mediated inflammation. In these mice, VEGF induced, through IL-13–dependent and –independent pathways, an asthma-like phenotype with inflammation, parenchymal and vascular remodeling, edema, mucus metaplasia, myocyte hyperplasia and airway hyper-responsiveness. VEGF also enhanced respiratory antigen sensitization and TH2 inflammation and increased the number of activated DC2 dendritic cells. In antigen-induced inflammation, VEGF was produced by epithelial cells and preferentially by TH2 versus TH1 cells. In this setting, it had a critical role in TH2 inflammation, cytokine production and physiologic dysregulation. Thus, VEGF is a mediator of vascular and extravascular remodeling and inflammation that enhances antigen sensitization and is crucial in adaptive TH2 inflammation. VEGF regulation may be therapeutic in asthma and other TH2 disorders.
