Lack of direct evidence for a functional role of voltage-operated calcium channels in juxtaglomerular cells [PDF]

open access: yes, 1990
In this study we have examined the role of voltage-gated calcium channels in the regulation of calcium in juxtaglomerular cells. Using a combination of patch-clamp and single-cell calcium measurement we obtained evidence neither for voltage-operated ...
