Cystic fibrosis is a genetic disease characterized by a dehydration of airway mucus leading to increased viscosity, significant inflammation, lung infections and tissue damage. Because progression of the disease cannot be solely explained by genetic factors, some studies are now interested in the intrinsic and extrinsic factors that exacerbate CF symptoms. Among those factors, reduced levels of specialized proresolving lipid mediators (SPM) in CF airway and exposure to air pollution have been reported. In addition, some pollutants have been shown to impact SPM biosynthesis. However, the possible role of air pollution on SPM metabolism dysregulation in CF and the role of SPM in protecting CF airways from air pollution induced damages have not been explored.
In our project, we use Scnn1b transgenic mice as a model for CF airway disease. In collaboration with the LISA (Interuniversity Laboratory of Atmospheric Systems / Laboratoire Interuniversitaire des Systèmes Atmosphériques), we study how exposure to a polluted atmosphere can impact the SPM and, more generally, the resolution of inflammation in the airway.
