Substrate-dependent metabolomic signatures of myeloperoxidase activity in airway epithelial cells: Implications for early cystic fibrosis lung disease

Myeloperoxidase is released by neutrophils in inflamed tissues. MPO oxidizes chloride, bromide, and thiocyanate to produce hypochlorous acid, hypobromous acid, and hypothiocyanous acid, respectively. These oxidants are toxic to pathogens, but may also react with host cells to elicit biological activity and potential toxicity. In cystic fibrosis and related diseases, increased neutrophil inflammation leads to increased airway MPO and airway epithelial cell exposure to its oxidants.

From hype to hope: Considerations in conducting robust microbiome science

Microbiome science has been one of the most exciting and rapidly evolving research fields in the past two decades. Breakthroughs in technologies including DNA sequencing have meant that the trillions of microbes (particularly bacteria) inhabiting human biological niches (particularly the gut) can be profiled and analysed in exquisite detail.

Hypoxia and sterile inflammation in cystic fibrosis airways: Mechanisms and potential therapies

In this review, we consider recent evidence regarding hypoxia and sterile inflammation in cystic fibrosis airways

Ultra low dose CT screen-detected non-malignant incidental findings in the Western Australian Asbestos Review Programme

The prevalence of LDCT-detected indeterminate lung nodules in 906 individuals with significant asbestos exposure was 8.5%, lower than many other CT studies

Genome Sequences of Two Lytic Staphylococcus aureus Bacteriophages Isolated from Wastewater

Two lytic double-stranded DNA (dsDNA) bacteriophages, belonging to the family Herelleviridae, were isolated from wastewater in Western Australia. Biyabeda-mokiny 2 appears to belong to the genus Kayvirus, and Koomba-kaat 1 to Silviavirus.

Automatic bronchus and artery analysis on chest computed tomography to evaluate the effect of inhaled hypertonic saline in children aged 3-6 years with cystic fibrosis in a randomized clinical trial

SHIP-CT showed that 48-week treatment with inhaled 7% hypertonic saline (HS) reduced airway abnormalities on chest CT using the manual PRAGMA-CF method relative to isotonic saline (IS) in children aged 3-6 years with cystic fibrosis (CF). An algorithm was developed and validated to automatically measure bronchus and artery (BA) dimensions of BA-pairs on chest CT. Aim of the study was to assess the effect of HS on bronchial wall thickening and bronchial widening using the BA-analysis.

Interleukin-1 is associated with inflammation and structural lung disease in young children with cystic fibrosis

Our data associates IL-1α with early structural lung damage in CF and suggests this pathway as a novel anti-inflammatory target

Use of a primary epithelial cell screening tool to investigate phage therapy in cystic fibrosis

This study demonstrates the feasibility of utilizing pre-clinical in vitro culture models to screen therapeutic candidates

Reduced transforming growth factor β1 (TGF-β1) in the repair of airway epithelial cells of children with asthma

Evidence into the role of TGF-β1 in airway epithelial repair in asthma is still controversial. This study tested the hypothesis that the reduced TGF-β1 levels previously observed in paediatric asthmatic airway epithelial cells directly contribute to the dysregulated repair seen in these cells.

Alpha-1 antitrypsin mitigates the inhibition of airway epithelial cell repair by neutrophil elastase

Free NE activity is deleterious for epithelial homeostasis and support the hypothesis that proteases in the airway contribute to CF structural lung disease
