Proximal and Distal Bronchioles Contribute to the Pathogenesis of Non-Cystic Fibrosis Bronchiectasis.

Non-cystic fibrosis bronchiectasis (NCFB) may originate in bronchiolar regions of the lung. Accordingly, there is a need to characterize the morphology and molecular characteristics of NCFB bronchioles. Test the hypothesis that NCFB exhibits a major component of bronchiolar disease manifest by mucus plugging and ectasia.

Secretory Cells Dominate Airway CFTR Expression and Function in Human Airway Superficial Epithelia.

Identification of the specific cell types expressing CFTR (cystic fibrosis [CF] transmembrane conductance regulator) is required for precision medicine therapies for CF. However, a full characterization of CFTR expression in normal human airway epithelia is missing. To identify the cell types that contribute to expression and function within the proximal-distal axis of the normal human lung.
