The importance of the (pro)renin receptor (PRR) in the function of the central nervous system is increasingly evident because PRR seems to play a role in neuronal control of cardiovascular function. PRR expression is elevated in the nucleus of the solitary tract (NTS) of spontaneously hypertensive rats (SHR). In this study, we tested the hypothesis that(More)
Angiotensin (Ang)-(1-7) is now recognized as a biologically active component of the renin-angiotensin system (RAS). The discovery of the angiotensin-converting enzyme homologue ACE2 revealed important metabolic pathways involved in the Ang-(1-7) synthesis. This enzyme can form Ang-(1-7) from Ang II or less efficiently through hydrolysis of Ang I to(More)
In this study, we evaluated whether the activation of endogenous angiotensin-converting enzyme 2 (ACE2) would improve the cardiovascular autonomic dysfunction of diabetic rats. Ten days after induction of type 1 diabetes (streptozotocin, 50 mg kg(-1) i.v.), the rats were treated orally with(More)
We evaluated the hypothesis that activation of endogenous angiotensin-converting enzyme (ACE) 2 would improve cardiac dysfunction induced by diabetes. Ten days after diabetes induction (streptozotocin, 50 mg/kg, i.v.), male Wistar rats were treated with the ACE2 activator(More)
Diminished release and function of endothelium-derived nitric oxide coupled with increases in reactive oxygen species production is critical in endothelial dysfunction. Recent evidences have shown that activation of the protective axis of the renin-angiotensin system composed by angiotensin-converting enzyme 2, angiotensin-(1-7), and Mas receptor promotes(More)
AT1 receptor subtype a (AT1Ra) expression is increased in the nucleus of the solitary tract (NTS) in spontaneously hypertensive rat (SHR) compared with Wistar Kyoto controls. However, the chronic role of AT1Ra in the NTS for cardiovascular control is not well understood. In this study, we investigated the hypothesis that the NTS AT1Ra is involved in the(More)
INTRODUCTION Angiotensin (Ang) A was first identified in human plasma and it differs from Ang II in Ala(1) instead of Asp(1). Here, we hypothesized that the actions of this peptide might explain, at least partially, the limited effects of AT1R antagonists in certain cardiovascular diseases. MATERIALS AND METHODS The effects of Ang A and Ang II on blood(More)

E ndothelial cells play a central role in maintaining vascular homeostasis and their dysfunction is associated with many forms of cardiovascular and metabolic diseases. 1 Diminished production and function of endothelium-derived nitric oxide and other vasoprotective factors and the exaggerated production of reactive oxygen species (ROS) and vasoconstrictors(More)
P ro)renin receptor (PRR) is highly expressed in many tissues , including those of the heart and brain, 1,2 and plays an important role in the maintenance of cardiovascular homeo-stasis in the periphery. 3,4 However, the role of PRR in the brain remains poorly understood. Despite intrinsically low renin concentrations in the brain, the ability of renin to(More)
Undernutrition during critical stages of development and childhood has important effects on cardiovascular homeostasis. The present study was undertaken to evaluate the in vivo and ex vivo cardiac function of rats submitted to postnatal protein restriction. Male Wistar rats (28 days old) were fed a regular (20%) or low-protein (6%) diet over 5 weeks. After(More)
