Investigating How Asthma Evolves and Affects Children

Bronchial Epithelial Cells

Bronchial epithelial cells differentiated at an ALI

Dr. Jason Debley's research has used epidemiological, clinical and molecular methods to understand how asthma evolves in early childhood, evaluate asthma's effect on airway structure and function, and investigate new ways to diagnose asthma in infants and toddlers with recurrent wheezing. He pioneered the measurement of exhaled nitric oxide in infants and his research has assessed the utility of this and other biomarkers for predicting asthma and decline in lung function among preschool children at risk for asthma.

The Debley Laboratory is engaged in an array of translational work investigating the role of the airway epithelium in childhood asthma. Nasal and bronchial airway epithelial cells are obtained from carefully characterized children with and without asthma, then differentiated in vitro using an air-liquid interface technique to allow for experiments investigating differential expression of innate and immunomodulatory factors by asthmatic epithelial cells, as well as differential asthmatic epithelial regulation of lung fibroblast expression of extracellular matrix, fibroblast- to-myofibroblast transformation, and airway smooth muscle proliferation.
