β-Adrenergic and angiotensin II type 1A receptors are therapeutic targets for the treatment of a number of common human diseases. Pharmacological agents designed as antagonists for these receptors have positively affected the morbidity and mortality of patients with hypertension, heart failure, and renal disease. Antagonism of these receptors, however, may only partially explain the therapeutic...

BACKGROUND Guidelines recommend continuation or initiation of guideline-directed medical therapy, including angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACEi/ARB), in hospitalized patients with heart failure with reduced ejection fraction. METHODS AND RESULTS Using the Get With The Guidelines-Heart Failure Registry, we linked clinical data from 16 052 heart failu...

AIMS Endothelial dysfunction is considered a surrogate marker for cardiovascular disease. Angiotensin II, the principal hormone of the renin angiotensin system, is known to promote atherogenesis. However, other angiotensin peptide fragments such as angiotensin IV possess biological activity that may in fact counter-regulate the actions of angiotensin II. Therefore, we investigated the role of a...

Angiotensin II (ANG II) is known to be a potent growth promoting factor for vascular smooth muscle cells and fibroblasts but little is known about its influence on growth in endothelial cells. We studied the effects of ANG II on endothelial growth and the role of the angiotensin receptor subtypes involved. Proliferation of rat coronary endothelial cells (CEC) and rat vascular smooth muscle cell...

Introduction Angiotensin II (ANG II) is known to be a potent growth promoting factor for vascular smooth muscle cells and fibroblasts but little is known about its influence on growth in endothelial cells. We studied the effects of ANG II on endothelial growth and the role of the angiotensin receptor subtypes involved. Proliferation of rat coronary endothelial cells (CEC) and rat vascular smoot...

Preeclampsia (PE) is a prevalent life-threatening hypertensive disorder of pregnancy associated with increased complement activation. However, the causative factors and pathogenic role of increased complement activation in PE are largely unidentified. Here we report that a circulating maternal autoantibody, the angiotensin II type 1 receptor agonistic autoantibody, which emerged recently as a p...

It is well known that angiotensin-(1-7) (Ang-(1-7)) counterbalances vasoconstrictive and proliferative functions of angiotensin II (Ang II), some of those actions are via inhibition of Ang II induced activation of mitogen-activated protein kinases(MAPK). This study investigated the effects of Ang-(1-7) on Ang II-mediated cell signaling pathways in mouse bone marrow-derived dendritic cells (DC)....
