Physiological aspects of angiotensin II-dependent hypertension: an overview


Hypertension is one of the main causes of death in developed and developing countries, inducing great impact in human health. Oxidative stress has been implicated as a key mechanism in Angiotensin II-dependent hypertension, since it modulates the baroreflex function in many pathophysiological processes. This study aimed to conduct a literature review addressing the recent mechanisms that promote changes in Angiotensin II-dependent hypertension. Here we highlighted two Angiotensin II-dependent hypertension models: two kidney-one-clip (2K1C) and deoxycorticosterone (DOCA-salt) hypertension. Bases on latest studies presented in important data base, it is possible to suggest that Angiotensin II is one of the main agents in hypertension development and the increase of this peptide is derived by multiple causes, which, in particular, acts as an inductor in oxidative stress production, in turn, it induces changes in a metalloprotease 17 (ADAM-17) and disruption of ACE2 compensatory activity. Thus, new tools that induce a reduction of oxidative stress promote beneficial effects, providing novel therapeutic targets to prevent and treat the Angiotensin II-dependent hypertension.
