Differential ANG II calcium responses suggest segment-specific arteriolar control in rodents; leaves open translation to human glomerular hemodynamics.
The magnitude of [Ca2+]i responses to ANG II in renal glomerular arterioles is related to the activation of dihydropyridine-sensitive voltage-operated calcium channels and muscular morphology, suggesting differential regulation of local renal microcirculation.
