Macrophage PD-1 associates with neutrophilia and reduced bacterial killing in early cystic fibrosis airway disease

Macrophages are the major resident immune cells in human airways coordinating responses to infection and injury. In cystic fibrosis, neutrophils are recruited to the airways shortly after birth, and actively exocytose damaging enzymes prior to chronic infection, suggesting a potential defect in macrophage immunomodulatory function.

DNA Methylation Profiles of Airway Epithelial Cells and PBMCs from Healthy, Atopic and Asthmatic Children

Allergic inflammation is commonly observed in a number of conditions that are associated with atopy including asthma, eczema and rhinitis.

The safety and feasibility of the inhaled mannitol challenge test in young children

Mannitol challenge tests are used clinically to diagnose asthma and, in particular, exercise-induced broncoconstriction (EIB) in adults and children above 6...

Elastase Exocytosis by Airway Neutrophils Associates with Early Lung Damage in Cystic Fibrosis Children

Protease elastase exocytosis by airway neutrophils occurs in all cystic fibrosis children, and its cellular measure correlates with early lung damage

CF derived scoring systems do not fully describe the range of structural changes seen on CT scans in PCD

Structural changes identified on CT scans in primary ciliary dyskinesia are not identical to those previously described in cystic fibrosis patients

Clinical investigation of respiratory system admittance in preschool children

We compared the ability of Ars, to standard oscillatory outcomes, to determine respiratory disease and differentiate responses to inhaled bronchial challenges.

Persistent activation of interlinked type 2 airway epithelial gene networks in sputum-derived cells from aeroallergen-sensitized symptomatic asthmatics

Our findings provide new insight into the molecular mechanisms operative at baseline in the airway mucosa in atopic asthmatic with natural aeroallergen exposure

Initial acquisition and succession of the cystic fibrosis lung microbiome is associated with disease progression in infants and preschool children

We characterized the lower airways microbiome using BAL samples obtained from clinically stable CF young children who underwent bronchoscopy and chest CT.

Protocol For Study Of Information Needs Of Parents Of Infants Newly Diagnosed With Cystic Fibrosis

This study aimed to investigate the information needs, priorities, and information-seeking behaviours of parents of infants newly diagnosed with CF.

Parental experiences of early pulmonary surveillance for children with cystic fibrosis: A research proposal for improved family psychosocial outcomes

The proposed study intends to explore parental experiences, including coping, related to their child's involvement in the early surveillance program.
