Intratubular Renin-Angiotensin System in Hypertension

Author(s): Yuki Suzaki, Minolfa C. Prieto-Carrasquero, Hiroyuki Kobori.

Abstract:

It is well recognized that the renin-angiotensin system plays an important role in the regulation of arterial pressure and sodium homeostasis. Recent years, many studies have shown that local tissue angiotensin II levels are differentially regulated and cannot be explained on the basis of circulating concentrations. All of the components needed for angiotensin II generation are present within the various compartments in the kidney including the renal interstitium and the tubular network. The cascade of the renin-angiotensin system demonstrates three major possible sites for the pharmacological interruption of the renin-angiotensin system: the interaction of renin with its substrate, angiotensinogen, the angiotensin converting enzyme, and angiotensin II type 1 receptors. This brief article will focus on the role of the intratubular renin-angiotensin system in the pathophysiology of hypertension and the responses to the renin-angiotensin system blockade by renin inhibitors, angiotensin converting enzyme inhibitors and angiotensin II type 1 receptor blockers.

Keywords: Renin-angiotensin system, hypertension, kidney, angiotensin converting enzyme inhibitors, angiotensin II type 1 receptor blockers
