Real‐world characteristics and treatment of cardiac transthyretin amyloidosis: A multicentre, observational study

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1203-1216, April 2025.
The 366 patients diagnosed with transthyretin amyloidosis cardiomyopathy (ATTR‐CM) were analyzed regarding their clinical characteristics in the first year after approval of tafamidis 61 mg for ATTR‐CM in Germany. Nearly two‐thirds of the patients were in an advanced disease stage and 64% met the key criteria of the “Transthyretin Amyloidosis ...

PET Imaging of the AT1 receptor with [11C]KR31173 [PDF]

open access: yesNuclear Medicine and Biology, 2006
The goal of this study was to investigate the binding characteristics of [(11)C]KR31173 and its applicability for PET studies of the AT(1) receptor (AT(1)R).Ex vivo biodistribution and pharmacology were tested in mice. PET imaging was performed in mice, beagle dogs and a baboon.

Holistic bone developing microenvironment engineered apoptotic extracellular vesicles recapitulate multidimensional developmental signatures in adult and senile bone repair

open access: yesInterdisciplinary Medicine, EarlyView.
The developing bone was identified as an M2a‐like macrophage driven immune microenvironment with multidimensional developmental signatures. hME‐ApoEVs were successfully fabricated via stimulating the M2a‐like developing microenvironment in vitro and confirmed its recapitulation of developmental features.

Coexpression of AT1 and AT2 receptors by human fibroblasts is associated with resistance to angiotensin II

open access: yes, 2005
Angiotensin II (AngII) is considered as a cytokine-like factor displaying a variety of proinflammatory and profibrotic cellular effects. Most of these effects seem mediated by AT1 signaling, whereas AT2 expression and function in adult human cells remain

Design of a MCoTI-Based Cyclotide with Angiotensin (1-7)-Like Activity

open access: yesMolecules, 2016
We report for the first time the design and synthesis of a novel cyclotide able to activate the unique receptor of angiotensin (1-7) (AT1-7), the MAS1 receptor.

Antibodies against AT1 receptors are associated with vascular endothelial and smooth muscle function impairment: protective effects of hydroxysafflor yellow A. [PDF]

open access: yesPLoS ONE, 2013
Ample evidence has shown that autoantibodies against AT1 receptors (AT1-AA) are closely associated with human cardiovascular disease. The aim of this study was to investigate mechanisms underlying AT1-AA-induced vascular structural and functional ...

Modeling the lung‒brain axis in critical illness: Multifactorial crosstalk through organoids and organ‐on‐a‐chip system

open access: yesVIEW, EarlyView.
Patients in intensive care units often experience lung injuries, complicated by brain problems. Advanced laboratory tools, organoids, and organs‐on‐chips facilitated the study of multiorgan interactions, help us understand the communication between the lungs and brain.

Angiotensin II type 1 receptor blocker losartan prevents and rescues cerebrovascular, neuropathological and cognitive deficits in an Alzheimer’s disease model

open access: yesNeurobiology of Disease, 2014
Angiotensin II (AngII) receptor blockers that bind selectively AngII type 1 (AT1) receptors may protect from Alzheimer’s disease (AD). We studied the ability of the AT1 receptor antagonist losartan to cure or prevent AD hallmarks in aged (~18 months at ...

Manifold active-state conformations in GPCRs: Agonist-activated constitutively active mutant AT1 receptor preferentially couples to Gq compared to the wild-type AT1 receptor

open access: yes, 2007
The angiotensin II type I (AT1) receptor mediates regulation of blood pressure and water-electrolyte balance by Ang II. Substitution of Gly for Asn111 of the AT1 receptor constitutively activates the receptor leading to Gq-coupled IP3 production ...

The potential for biased signalling in the P2Y receptor family of GPCRs

open access: yesBritish Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora
