Airway epithelial cell–pathogen interactions

AbstractCystic fibrosis (CF) airway becomes colonized with only a limited number of bacterial pathogens. It is of paramount importance to establish in vitro and in vivo models to better understand bacterial–host interactions under CF-like conditions. In this article, in vitro methods suitable to study Pseudomonas aeruginosa (Pa) and Staphylococcus aureus (Sa) adherence to and uptake by airway epithelial cells are described. Acute and chronic respiratory infection models, which have been used in CF transgenic mice and mimic human CF lung pathology, are also taken into consideration
