CFTR encodes the cystic fibrosis transmembrane conductance regulator, an ATP-gated chloride channel expressed primarily in epithelial cells. CFTR regulates chloride ion transport across epithelial surfaces, maintaining salt and water homeostasis. Although primarily studied in lung and pancreas, CFTR is also expressed in the brain, particularly in astrocytes and certain neurons. Brain CFTR may regulate neuronal excitability, astrocytic volume, and neuroinflammation. CFTR dysfunction may contribute to neurodegenerative processes.
Expression in brain is lower than in epithelial tissues but detectable. Found in astrocytes, microglia, and some neurons. CFTR expression in brain may be upregulated under inflammatory conditions.
