Blocking Notch3 Signaling Abolishes MUC5AC Production in Airway Epithelial Cells from Asthmatics

We demonstrate that NOTCH3 is a regulator of MUC5AC production

Cystic Fibrosis Early Surveillance Program

Researchers are able to track the progress of lung disease through a comprehensive longitudinal set of biological samples, images and data archives.

Rhinovirus Infection Is Associated With Airway Epithelial Cell Necrosis and Inflammation via Interleukin-1 in Young Children With Cystic Fibrosis

This study found rhinovirus infection drives necrotic cell death in cystic fibrosis airway epithelial cells

A structure-function analysis of interspecies antagonism by the 2-heptyl-4-alkyl-quinolone signal molecule from Pseudomonas aeruginosa

Here we show that antibacterial activity of 4-hydroxy-2-heptylquinoline against Vibrionaceae is species-specific

Advancing Innovation in Respiratory Health

The Advancing Innovation in Respiratory (AIR) Health Team is a multi-disciplinary group with skills in clinical medicine, physiology, psychology, and in cellular and molecular biology, that are committed to improving the lives of children with respiratory diseases and their families.

Changing Prevalence of Lower Airway Infections in Young Children with Cystic Fibrosis

Aspergillus species and P. aeruginosa are commonly present in the lower airways from infancy

Exposure to bile leads to the emergence of adaptive signaling variants in the opportunistic pathogen pseudomonas aeruginosa

Adaptive variants of P. aeruginosa that arise following long term bile exposure enables the emergence of ecologically competitive sub-populations

Conservation of gene expression patterns between the amniotic and nasal epithelium at birth

Amniotic epithelial cells are fetal-derived stem cells, capable of differentiating into all three germ layers, including mature epithelial cell populations. Here, we hypothesised that the amniotic epithelium might serve as a surrogate tissue source for investigating transcriptional profiles in the respiratory epithelium of newborns.

Bile acids in the lower airways is associated with airway microbiota changes in chronic obstructive pulmonary disease: an observational study

Chronic obstructive pulmonary disease (COPD) is a complex disorder with a high degree of interindividual variability. Gastrointestinal dysfunction is common in patients with COPD and has been proposed to influence the clinical progression of the disease. Using the presence of bile acid(s) (BA) in bronchoalveolar lavage (BAL) fluid as a marker of gastric aspiration, we evaluated the relationships between BAs, clinical outcomes and bacterial lung colonisation.

Phage therapy to treat cystic fibrosis Burkholderia cepacia complex lung infections: perspectives and challengesge

Burkholderia cepacia complex is a cause of serious lung infections in people with cystic fibrosis, exhibiting extremely high levels of antimicrobial resistance. These infections are difficult to treat and are associated with high morbidity and mortality.
