Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Negative impact of β-arrestin-1 on post-myocardial infarction heart failure via cardiac and adrenal-dependent neurohormonal mechanisms [PDF]

open access: yes, 2014
β-Arrestin (βarr)-1 and β-arrestin-2 (βarrs) are universal G-protein-coupled receptor adapter proteins that negatively regulate cardiac β-adrenergic receptor (βAR) function via βAR desensitization and downregulation.

Mechanism of β-Adrenergic Receptor Desensitization in Cardiac Hypertrophy Is Increased β-Adrenergic Receptor Kinase [PDF]

open access: yesJournal of Biological Chemistry, 1997
Pressure overload cardiac hypertrophy in the mouse was achieved following 7 days of transverse aortic constriction. This was associated with marked beta-adrenergic receptor (beta-AR) desensitization in vivo, as determined by a blunted inotropic response to dobutamine. Extracts from hypertrophied hearts had approximately 3-fold increase in cytosolic and

Semaglutide normalizes increased cardiomyocyte calcium transients in a rat model of high fat diet‐induced obesity

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1386-1397, April 2025.
Sequeira et al. reveal how the glucagon‐like peptide‐1 receptor agonist (GLP‐1‐RA) semaglutide restores cardiomyocyte function in rats subjected to a high‐fat/high‐fructose diet (HFD). Employing fluorescence‐ and patch‐clamp technology in isolated cardiac myocytes, they demonstrate that semaglutide reverses HFD‐induced activation of L‐type calcium ...

Contribution of the sympathetic nervous system to the pathogenesis of salt-sensitive hypertension [PDF]

open access: yes, 2016
Dysregulation of the sodium-chloride cotransporter (NCC) is believed to significantly impact blood pressure. Recent studies have implicated overactivity of the sympathetic nervous system as a mechanism driving renal NCC dysregulation to evoke the ...

Cilostazol in patients with heart failure and preserved ejection fraction—The CLIP‐HFpEF trial

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1437-1446, April 2025.
• Cilostazol is an oral PDE‐3 inhibitor that may have advantageous effects in heart failure with preserved ejection fraction (HFpEF). • Cilostazol significantly improved short‐term heart failure‐related health status scores (KCCQ‐12) and NT‐proBNP levels when compared to placebo.

Nanodelivery of a functional membrane receptor to manipulate cellular phenotype. [PDF]

open access: yes, 2018
Modification of membrane receptor makeup is one of the most efficient ways to control input-output signals but is usually achieved by expressing DNA or RNA-encoded proteins or by using other genome-editing methods, which can be technically challenging ...

Status epilepticus: Updates on mechanisms and treatments

open access: yesEpilepsia Open, EarlyView.
Abstract Status epilepticus (SE) consists of prolonged, self‐sustaining seizures and is a common neurological emergency that causes respiratory compromise and neuronal injury. Without prompt treatment, the seizures can become resistant to benzodiazepines, leading to the progressive evolution of established, refractory, and super‐refractory SE.

β-adrenergic receptors and G protein-coupled receptor kinase-2 in Alzheimer's disease: a new paradigm for prognosis and therapy? [PDF]

open access: yes, 2013
Alzheimer's disease (AD) is a devastating form of dementia that imposes a severe burden on health systems and society. Although several aspects of AD pathogenesis have been elucidated over the last few decades, many questions still need to be addressed ...

Mechanisms of Action Involved in the In Vivo Gastroprotective Response of Fruits: A Systematic Review

open access: yesFood Frontiers, EarlyView.
ABSTRACT Gastrointestinal diseases remain a significant global health concern, primarily due to the limitations of current pharmacological treatments, which often come with adverse side effects and high recurrence rates. This situation highlights the urgent need for safer and more effective alternatives.
