Abstract

Pseudomonas aeruginosa is an opportunistic pathogen known for its ability to cause chronic lung infections in patients with cystic fibrosis.  Such infections lead to chronic inflammation, deteriorating lung function and increased morbidity and mortality. P. aeruginosa is also a major cause of nosocomial infections. It is problematic to manage clinically as it is intrinsically resistant to many antibiotics. Recently, the WHO named P. aeruginosa as a Priority 1 pathogen for which new antibiotics and treatments are desperately needed. Antibodies normally protect individuals against infection. However, we recently identified patients with chronic P. aeruginosa infection that produced specific antibody that protected the infecting bacterium from both serum- and cell-mediated killing. We demonstrated that these ‘inhibitory antibodies’ (iAb) belong to the IgG2 subclass and target lipopolysaccharide on the bacterial surface. Importantly, patients with iAb had worse lung function than infected patients with normal serum killing. Here we describe the successful treatment of patients with chronic P. aeruginosa infections by modulating antibodies. These findings have important consequences for vaccine development and the treatment of multidrug resistant infections.

Professor Henderson's research group studies bacteria and their interaction with humans and animals. Their research is focused on the discovery of genes that are important for building the cell membrane of bacteria. Using genetic, biochemical and structural techniques they study the activity, regulation and function of these genes and their products. Using mice as a model they assess if the products of these genes are important for infectious disease. The group's purpose is to apply this understanding to the diagnosis, prevention and treatment of infections that can lead to life-threatening disease in humans and animals. Professor Henderson seeks targets for developing new antibiotics, vaccines and novel therapies.
