CFTR expression decreases with age in several airway cell types.

ABSTRACT: The mucociliary clearance (MC) system is a vital host defense against infection in the lung. MC system function is dependent on ciliary density, structure, and function and airway surface liquid (ASL) composition and hydration. Animal and human studies indicate that MC rate decreases with age which may contribute to the increased rates of pulmonary infection experienced by older people. The Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene encodes an anion channel on epithelial surfaces that plays a key role in maintaining ASL hydration. Failure or dysfunction of CFTR could result in the dehydration of airway mucus, depressing MC. Here we use two available databases including bulk (GTEx) and single-cell (CELLxGENE) sequencing data from the lung to determine if CFTR expression
