The longitudinal microbial and metabolic landscape of infant cystic fibrosis: the gut-lung axis

In cystic fibrosis, gastrointestinal dysfunction and lower airway infection occur early and are independently associated with poorer outcomes in childhood. This study aimed to define the relationship between the microbiota at each niche during the first 2 years of life, its association with growth and airway inflammation, and explanatory features in the metabolome.

Azithromycin reduces bronchial wall thickening in infants with cystic fibrosis

COMBAT-CF showed that children aged 0-3 years treated with azithromycin did clinically better than placebo but there was no effect on CT-scores. We reanalysed CTs using an automatic bronchus-artery (BA) analysis.

Oxidative stress and abnormal bioactive lipids in early cystic fibrosis lung disease

Several lipid biomarkers of early cystic fibrosis lung disease were identified, which point toward potential disease monitoring and therapeutic approaches

Early lung surveillance of cystic fibrosis: what have we learnt?

Newborn screening (NBS) for cystic fibrosis (CF) provides an opportunity to commence management and therapeutic interventions significantly earlier

Research

Infective respiratory syncytial virus is present in human cord blood samples and most prevalent during winter months

Human respiratory syncytial virus (RSV) remains the most common cause of severe lower respiratory tract disease amongst infants, and continues to cause annual epidemics of respiratory disease every winter worldwide.

Airway epithelial repair in health and disease: Orchestrator or simply a player?

This review attempts to highlight migration-specific and cell-extracellular matrix (ECM) aspects of repair used by epithelial cells

Autophagy modulates growth and development in the moss Physcomitrium patens

Physcomitrium patens apical growing protonemal cells have the singularity that they continue to undergo cell divisions as the plant develops. This feature provides a valuable tool to study autophagy in the context of a multicellular apical growing tissue coupled to development. Herein, we showed that the core autophagy machinery is present in the moss P. patens, and characterized the 2D and 3D growth and development of atg5 and atg7 loss-of-function mutants under optimal and nutrient-deprived conditions.

Association between early respiratory viral infections and structural lung disease in infants with cystic fibrosis

Infants with cystic fibrosis (CF) develop structural lung disease early in life, and viral infections are associated with progressive lung disease. We hypothesized that the presence of respiratory viruses would be associated with structural lung disease on computed tomography (CT) of the chest in infants with CF.

Lipopolysaccharide-induced interferon response networks at birth are predictive of severe viral lower respiratory infections in the first year of life

Appropriate innate immune function is essential to limit pathogenesis and severity of severe lower respiratory infections (sLRI) during infancy, a leading cause of hospitalization and risk factor for subsequent asthma in this age group.
