Does dopamine connect the dots in ADPKD?

Abstract

Healthy autosomal dominant polycystic kidney disease (ADPKD) patients with normal kidney function demonstrate reduced endothelial-dependent vasodilation that improves with increasing local dopamine levels. Dopamine regulates renal sodium excretion, and dopamine receptors are located on primary cilia in both vascular and renal tubular epithelial cells. The study by Lorthioir and colleagues links endothelial function and dopamine availability in ADPKD patients.
