Physiology and Pathophysiology of the Intrarenal Renin-Angiotensin System: An Update.

open access: yesJournal of the American Society of Nephrology, 2017
The renin-angiotensin system (RAS) has a pivotal role in the maintenance of extracellular volume homeostasis and blood pressure through complex mechanisms.

HNF3α Targets Nckap1l and Promotes Renal Fibrosis Following Ischemia‐Reperfusion Injury

open access: yesAdvanced Science, EarlyView.
Hepatocyte Nuclear Factor 3 alpha (HNF3α) is significantly upregulated in renal tubular epithelial cells of CKD patients and fibrotic mice. Deletion of HNF3α mitigates IRI‐induced renal fibrosis, while overexpression worsens it. HNF3α directly regulates NCK‐associated protein 1‐like (Nckap1l), whose overexpression exacerbates fibrosis.

Perivascular adipose tissue inflammation in vascular disease [PDF]

open access: yes, 2017
Perivascular adipose tissue (PVAT) plays a critical role in the pathogenesis of cardiovascular disease. In vascular pathologies, perivascular adipose tissue increases in volume and becomes dysfunctional, with altered cellular composition and molecular ...

Angiotensin Receptors and the Vagal System

open access: yesClinical and Experimental Hypertension. Part A: Theory and Practice, 1988
Angiotensin II (Ang II) is known to attenuate the vagal component of the baroreflex at both central and peripheral cardiac sites. Ang II receptor binding sites occur in both the nucleus of the solitary tract (NTS), where they are associated with vagal afferent terminals, and in the dorsal motor nucleus of vagus.

Mas Signaling Potentiates Neutrophil Extracellular Traps Formation Induced by Endothelial Cells Derived S1P in Mice with Acute Liver Failure

open access: yesAdvanced Science, EarlyView.
In mice challenged with lipopolysaccharide/D‐galactosamine (L/G), Mas signaling increased SHP2 in hepatic Col4a1+ endothelial cells, inhibiting farnesoid X receptor (FXR), potentially due to enterogenic deoxycholic acid. This inhibition activates sphingosine‐1‐phosphate‐induced Raf/MEK/ERK signaling in Cldn1+CD177+ neutrophils, causing neutrophil ...

Vascular fibrosis in aging and hypertension: molecular mechanisms and clinical implications [PDF]

open access: yes, 2016
Aging is the primary risk factor underlying hypertension and incident cardiovascular disease. With aging, the vasculature undergoes structural and functional changes characterized by endothelial dysfunction, wall thickening, reduced distensibility, and ...

PRMT1 Ablation in Endothelial Cells Causes Endothelial Dysfunction and Aggravates COPD Attributable to Dysregulated NF‐κB Signaling

open access: yesAdvanced Science, EarlyView.
This study investigates the role of protein arginine methyltransferase 1 (PRMT1) in endothelial cells (ECs) in chronic obstructive pulmonary disease (COPD). Mice with endothelial‐specific PRMT1 deletion develop pulmonary hemorrhage, inflammation, and apoptosis, driven by excessive nuclear factor kappa B activation.

Endothelial Vasodilator Angiotensin Receptors are Changing in Mice with Ageing

open access: yesResearch in Molecular Medicine, 2014
Background: The vascular function of Angiotensin II-type-2 receptors in adults is controversial. We sought their location and function in mouse aortic rings at young and old mice.

G protein-coupled receptor dimerisation: molecular basis and relevance to function [PDF]

open access: yes, 2007
The belief that G protein-coupled receptors exist and function as monomeric, non-interacting species has been largely supplanted in recent years by evidence, derived from a range of approaches, that indicate they can form dimers and/or higher-order ...

hESCs‐derived Organoids Achieve Liver Zonation Features through LSEC Modulation

open access: yesAdvanced Science, EarlyView.
This article addresses the absence of zonation features in current organoid models by co‐culturing human embryonic stem cell‐derived hepatocytes with liver sinusoidal endothelial cells exhibiting distinct zonal characteristics. It demonstrates that differential WNT2 signaling from endothelial cells modulates hepatocyte zonation and metabolic functions,
