Official title

Pulmonary Vascular Disease in Cystic Fibrosis

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

In this project, the investigators seek to understand the role of endothelial cells in Cystic Fibrosis (CF) lung disease. This objective will be achieved by conducting a cross sectional clinical study to define the morphology of the pulmonary circulation across a range of lung function coupled with a mechanistic study of the effect of dysfunctional cystic fibrosis transmembrane conductance regulator (CFTR) in endothelial cells on vasculogenesis, epithelial morphogenesis and epithelial CFTR function. Toward that end, the investigators propose the following hypotheses; (a). Loss of pulmonary small blood vessels begins early in the CF lung and worsens with disease progression, (b).VEGFR2-CFTR interactions happen at the plasma membrane of endothelial cells and is likely to be involved in transendothelial ion transport (c) impaired VEGFR2-CFTR interactions on the endothelial cells will have a profound effect on vasculogenesis, epithelial morphogenesis and ion transport. The first hypotheses will be tested through this clinical study. The following 2 hypotheses will be tested through laboratory studies that do not involve human subjects.
