Swelling-induced, CFTR-independent ATP release from a human epithelial cell line: lack of correlation with volume-sensitive cl(-) channels.


To examine a possible relation between the swelling-induced ATP release pathway and the volume-sensitive Cl(-) channel, we measured the extracellular concentration of ATP released upon osmotic swelling and whole-cell volume-sensitive Cl(-) currents in a human epithelial cell line, Intestine 407, which lacks expression of cystic fibrosis transmembrane… (More)
