Abstract Loss-of-function mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene cause cystic fibrosis (CF). The middle ear and eustachian tube could be adversely affected in CF. In this study, we provide evidence of the role of CFTR function in conductive hearing. We developed an in-situ model to determine CFTR dependent fluid secretion in the middle ear using native mouse auditory capsule.

The World Health Organization(WHO) has reported a worldwide surge in cases of cholera caused by the intestinal pathogen Vibrio cholerae, and, combined, such surges have claimed several million lives, mostly in early childhood. Elevated cAMP production in intestinal epithelial cells challenged with cholera toxin (CTX) results in diarrhea due to chloride transport by a cAMP-activated channel, the cystic fibrosis transmembrane conductance regulator (CFTR).
