Receptor regulation of the volume-sensitive efflux of taurine and iodide from human SH-SY5Y neuroblastoma cells: differential requirements for Ca(2+) and protein kinase C.

Abstract

The basal (swelling-induced) and receptor-stimulated effluxes of (125)I(-) and taurine have been monitored to determine whether these two osmolytes are released from human SH-SY5Y cells under hypotonic conditions via common or distinct mechanisms. Under basal conditions, both (125)I(-) (used as a tracer for Cl(-)) and taurine were released from the cells in… (More)
