Cystic fibrosis transmembrane conductance regulator (CFTR) is a cAMP-regulated chloride channel located primarily on the apical surface of epithelial cells that line various organs, including the airways and the gut. CFTR dysfunction is detrimental and may result in life-threatening medical disorders. Dr. Naren's laboratory studies two such disorders; (1) Cystic fibrosis, a lethal genetic disease that affects mostly the Caucasian population (>30,000 in USA), in which the CFTR chloride channel is HYPO-functional and (2) Secretory diarrhea, a disease affecting millions of children worldwide, in which HYPER-function of the CFTR chloride channel can occur due to infectious toxins, such as cholera toxin and E. coli enterotoxin. His lab is interested in identifying interactions between CFTR and its binding partners and defining how spatiotemporal regulation of CFTR-containing macromolecular complexes in the apical compartment of polarized epithelial cells lining the secretory epithelia regulates overall fluid secretion. Our studies will identify new drug targets for cystic fibrosis, secretory diarrhea, and other diseases resulting from CFTR dysfunction and provide insights into the etiology of diseases associated with CFTR-interacting molecules.
