Contribution to Science
The focus of my research is on the antibacterial innate immunity of the airway epithelia, in particular how does the lack of a chloride channel ‘CFTR’ results in pulmonary lung infections. I have divided the research in my laboratory into four main areas.
First, to investigate the antimicrobial properties of the airway surface liquid and how they affect bacterial colonization in cystic fibrosis. My laboratory investigates this question using primary cultures of human airway epithelia at the air liquid interface, animal models including mice and pigs with deletion of the CFTR gene, and humans with cystic fibrosis. We are currently studying the effect pH on airway innate immunity.

Second, I investigate the development of vectors for gene therapy in cystic fibrosis. I initially worked on non viral vectors, and described the molecular mechanism for transfection. I also tested a non-viral vector and an adenovirus vector in human experiments to investigate the proof of principle for gene transfer to the airways of patients with CF. Currently, I have been using ‘directed evolution’ to select adeno-associated viruses that efficiently target the airway epithelia of humans and pigs. The porcine model of Cystic Fibrosis will allow us to ask the question if ‘gene transfer’ can result in ‘gene therapy’.

Third, my laboratory also investigates how the receptor for adenovirus regulates epithelial functions as well as pathogenesis of adenovirus airway infection.

Finally, I have been investigating the effect of an endogenous lactonase ‘paraoxonase’ that can degrade quorum-sensing molecules used by Pseudomonas Aeruginosa. This family of proteins is ubiquitously expressed in the airways and may represent a novel form of innate immunity against quorum-sensing bacteria.
