Summary
Cystic fibrosis (CF) is the most common autosomal recessive disorder in humans, affecting 1:2000 people. Mortality is often caused by Pseudomonas aeruginosa lung infections which have recently been shown to occur not only environmentally but also via person-person contact, usually during CF clinic visits. This project will elucidate the molecular traits responsible for these 'epidemic' P. aeruginosa infections, with the aim of finding novel therapeutics and infection control strategies.
The lung in people with the genetic disorder cystic fibrosis (CF) contains increase amounts of iron, which promotes bacterial infection. In this research project we are using mouse models of CF and airway cells obtained from people with CF to investigate the underlying mechanism of abnormal iron regulation. We are also examining the therapeutic potential of compounds that interfere with the ability of bacteria to obtain iron to see whether this can overcome antibiotic resistance.
