Vulnerable from the first breath - epithelial dysfunction and respiratory outcomes in children

We have been studying the importance of the epithelial cells lining the airways in the nose and lungs.

Innate inflammatory responses of pediatric cystic fibrosis airway epithelial cells: Effects of nonviral and viral stimulation

There is controversy regarding whether cystic fibrosis (CF) airway epithelial cells (AECs) are intrinsically proinflammatory.

Deep inspiration and airway physiology: human, canine, porcine, or bovine?

Airway Epithelial Research

The Airway Epithelial Research Team is investigating the role of the epithelium in the development of airway diseases including asthma, cystic fibrosis and lung transplant rejection.

Toxicity of plastic diesel exhaust in primary human airway epithelial cell cultures

Plastic pyrolysis oil, which can be produced with similar properties as diesel fuel (plastic diesel), can be used as an alternative to mineral diesel (ULSD) to run a diesel engine. This presents a potential method for recycling waste plastic. Typically plastic diesel is blended with mineral diesel, and oxygenated fuel additives such as ethers added to improve resulting fuel properties.

Stochastic models indicate rapid smallpox spread and mass mortality of Indigenous Australians after colonial exposure

The impact of smallpox (variola) on Aboriginal communities in Australia beginning in 1789 was catastrophic and continues to cause intergenerational trauma. Historically biased perspectives and contemporary misinformation of the disease's introduction and spread impede modern-day truth-telling and efforts towards reconciliation and national healing.

Regulating the Irregular: Phage Therapy and the Case for a Regulatory Sandbox Approach in Australia

Bacteriophages (phages) are viruses that selectively kill bacteria and offer a promising option to address the growing global pandemic of antimicrobial-resistant infections. However, phage therapy does not easily align with traditional regulatory pathways designed for fixed-composition chemical drugs or biologics with fixed non-evolving compositions.

High prevalence of mgrB-mediated colistin resistance among carbapenem-resistant Klebsiella pneumoniae is associated with biofilm formation, and can be overcome by colistin-EDTA combination therapy

The global prevalence of colistin-resistant Klebsiella pneumoniae (ColRkp) facilitated by chromosomal and plasmid-mediated Ara4N or PEtN-remodeled LPS alterations has steadily increased with increased colistin usage for treating carbapenem-resistant K. pneumoniae (CRkp).

Pseudomonas aeruginosa modulates neutrophil granule exocytosis in an in vitro model of airway infection

A population of neutrophils recruited into cystic fibrosis (CF) airways is associated with proteolytic lung damage, exhibiting high expression of primary granule exocytosis marker CD63 and reduced phagocytic receptor CD16. Causative factors for this population are unknown, limiting intervention. Here we present a laboratory model to characterize responses of differentiated airway epithelium and neutrophils following respiratory infection.

Primary Nasal Epithelial Cells as a Surrogate Cell Culture Model for Type-II Alveolar Cells to Study ABCA-3 Deficiency

ATP Binding Cassette Subfamily A Member 3 (ABCA-3) is a lipid transporter protein highly expressed in type-II alveolar (AT-II) cells. Mutations in ABCA3 can result in severe respiratory disease in infants and children. To study ABCA-3 deficiency in vitro, primary AT-II cells would be the cell culture of choice although sample accessibility is limited. Our aim was to investigate the suitability of primary nasal epithelial cells, as a surrogate culture model for AT-II cells, to study ABCA-3 deficiency.
