Abstract
The effect of bradykinin on cytoplasmic Ca2+ concentration in rabbit papillary collecting tubule cells was determined using the fluorescent indicator Quin 2. Bradykinin stimulated a rapid increase in intracellular Ca2+. The rise in Ca2+ was dose dependent, persisted for less than 90 seconds and was independent of extracellular calcium. The ED50 for bradykinin induced changes in [Ca2+]i paralleled that observed previously for hormone-induced PGE2 formation as well as for inositol trisphosphate labelling. These studies provide additional support for the role of Ca2+ as a second messenger for bradykinin in renal papillary collecting tubule cells.
