Salt reabsorption by the human sweat duct is markedly reduced in cystic fibrosis (CF). We used fluorescence-digital imaging microscopy in combination with a halide-specific fluorescent dye [6-methoxy-N-(3-sulfopropyl)quinolinium (SPQ)] to determine if this defective salt reabsorption is referable to a reduced plasma membrane Cl- permeability of the epithelial cells that line the sweat duct. Sweat duct cells were cultured from explants of normal and CF reabsorptive duct and loaded with SPQ, the… CONTINUE READING
