Pseudomonas aeruginosa vesicles associate with and are internalized by human lung epithelial cells

Abstract excerpt

BACKGROUND: Pseudomonas aeruginosa is the major pathogen associated with chronic and ultimately fatal lung infections in patients with cystic fibrosis (CF). To investigate how P. aeruginosa-derived vesicles may contribute to lung disease, we explored their ability to associate with human lung cells. RESULTS: Purified vesicles associated with lung cells and were internalized in a time- and dose-dependent manner....
