Stability Considerations for Bacteriophages in Liquid Formulations Designed for NebulizationPulmonary bacterial infections present a significant health risk to those with chronic respiratory diseases including cystic fibrosis and chronic-obstructive pulmonary disease. With the emergence of antimicrobial resistance, novel therapeutics are desperately needed to combat the emergence of resistant superbugs.

Novel intranasal phage-CaEDTA-ceftazidime/avibactam triple combination therapy demonstrates remarkable efficacy in treating Pseudomonas aeruginosa lung infectionGiven the rise of multidrug-resistant (MDR) Pseudomonas aeruginosa infections, alternative treatments are needed. Anti-pseudomonal phage therapy shows promise, but its clinical application is limited due to the development of resistance and a lack of biofilm penetration.

Productive infection of human embryonic stem cell-derived nkx2.1+ respiratory progenitors with human rhinovirus.Our experiments provide proof of principle for the use of PSC-derived respiratory epithelial cells in the study of cell-virus interactions.

Effect of human rhinovirus infection on airway epithelium tight junction protein disassembly and transepithelial permeabilityHRV-1B infection directly alters human airway epithelial TJ expression leading to increased epithelial permeability potentially via antiviral response of IL-15

Defective cell migration as a mechanism of dysregulated asthmatic airway repairThe findings from this study show that in children with asthma this protective barrier is different from children without asthma.

ACE2 expression is elevated in airway epithelial cells from older and male healthy individuals but reduced in asthmaCOVID-19 is complicated by acute lung injury, and death in some individuals. It is caused by SARS-CoV-2 that requires the ACE2 receptor and serine proteases to enter AEC. We determined what factors are associated with ACE2 expression particularly in patients with asthma and COPD. We obtained lower AEC from 145 people from two independent cohorts, aged 2-89 years, Newcastle (n = 115) and Perth (n = 30), Australia. The Newcastle cohort was enriched with people with asthma (n = 37) and COPD (n = 38). Gene expression for ACE2 and other genes potentially associated with SARS-CoV-2 cell entry was assessed by qPCR, and protein expression was confirmed with immunohistochemistry on endobronchial biopsies and cultured AEC.

Persistent induction of goblet cell differentiation in the airways: Therapeutic approachesHere we review the current knowledge of key molecular pathways that are dysregulated during persistent goblet cell differentiation
Research
Accumulation mode particles and LPS exposure induce TLR-4 dependent and independent inflammatory responses in the lungWe aimed to delineate the effects of LPS and AMP on airway inflammation, and potential contribution to airway disease by measuring airway inflammatory responses
Research
Conditionally reprogrammed primary airway epithelial cells maintain morphology, lineage and disease specific functional characteristicsHere, we show that conditionally reprogrammed airway epithelial cells (CRAECs) can be established from both healthy and diseased phenotypes.

Ancestral SARS-CoV-2, but not Omicron, replicates less efficiently in primary pediatric nasal epithelial cellsChildren typically experience more mild symptoms of Coronavirus Disease 2019 (COVID-19) when compared to adults. There is a strong body of evidence that children are also less susceptible to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection with the ancestral viral isolate.
