Beta-Adrenergic Receptor Blockade By Propranolol Enhances Retention In A Multitrial Passive-Avoidance Procedure [PDF]

open access: yes, 2000
The effect of beta -adrenergic receptor blockade on retention in a mildly aversive passive-avoidance procedure was investigated. Rats were given passive-avoidance training-1 trial per day for 4 days-and were administered saline, the centrally and ...

Mapping the druggable allosteric space of G-protein coupled receptors: a fragment-based molecular dynamics approach. [PDF]

open access: yes, 2010
To address the problem of specificity in G-protein coupled receptor (GPCR) drug discovery, there has been tremendous recent interest in allosteric drugs that bind at sites topographically distinct from the orthosteric site. Unfortunately, structure-based

Augmented β2-adrenergic signaling dampens the neuroinflammatory response following ischemic stroke and increases stroke size

open access: yesJournal of Neuroinflammation, 2019
Background Ischemic stroke provokes a neuroinflammatory response and simultaneously promotes release of epinephrine and norepinephrine by the sympathetic nervous system.

Targeting the ARRDC3–DRP1 Axis via hUMSC‐Derived Exosomal CRYAB for Neuroprotection in Cerebral Ischemia/Reperfusion Injury

open access: yesAdvanced Healthcare Materials, EarlyView.
Intranasally administered hUMSC‐derived exosomes modulate the CRYAB–ARRDC3–Drp1 axis, alleviating mitochondrial dysfunction and ferroptosis, enhancing neuronal survival, reducing oxidative stress, and promoting functional recovery in ischemia‐reperfusion injury, offering a promising therapeutic strategy for ischemic stroke.

Anti-adrenergic effects of endothelin on human atrial action potentials are potentially anti-arrhythmic [PDF]

open access: yes, 2006
Endothelin-1 (ET-1) is elevated in patients with atrial fibrillation (AF) and heart failure. We investigated effects of ET-1 on human atrial cellular electrophysiological measurements expected to influence the genesis and maintenance of AF.

A Tri‐Culture Heart‐on‐a‐Chip Platform With iPSC‐Derived Cardiac Cells for Predictive Cardiotoxicity Testing

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents the first entirely isogenic heart‐on‐chip, unifying cardiomyocytes, fibroblasts, and endothelial cells from a single iPSC source. The platform reveals a critical biological insight: the endothelium actively shields cardiac tissue from drug‐induced toxicity, challenging the predictive accuracy of conventional, avascular models for ...

Synthesis, Docking Study and β-Adrenoceptor Activity of Some New Oxime Ether Derivatives

open access: yesMolecules, 2014
A new series of oxime ethers 4a–z was designed and synthesized to test the blocking activity against β1 and β2-adrenergic receptors. Docking of these ether derivatives into the active site of the identified 3D structures of β1 and β2-adrenergic receptors

Serum Activity Against G Protein–Coupled Receptors and Severity of Orthostatic Symptoms in Postural Orthostatic Tachycardia Syndrome

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Postural orthostatic tachycardia syndrome (POTS) is characterized by excessive heart rate increase on standing and orthostatic intolerance. Previous data indicate autoimmune involvement.

A Systematic Review on the Role of Adrenergic Receptors in Angiogenesis Regulation in Health and Disease

open access: yesInternational Journal of Translational Medicine, 2021
Angiogenesis is essential during development or when tissue restoration and oxygenation is required. Limited or excessive formation of blood vessels is a hallmark of several pathologies, and many angiogenesis-related pathways are being studied to ...
