Beta 2-adrenergic pathway combats Alzheimer’s disease: Restoring cognition and synaptic integrity

Neural Regeneration Research
Alzheimer’s disease is typified by amyloid-beta oligomer-mediated synaptic disruption, neuroinflammation, and mitochondrial loss of function, culminating in cognitive decline.

Urology Residency Directors' Awareness of Association between α-Adrenergic Antagonists and Floppy Iris Syndrome and Practice Patterns Regarding Prophylactic α-Adrenergic Antagonists

Journal of Academic Ophthalmology, 2019
Purpose The use of prophylactic α-adrenergic receptor antagonists prior to surgery is associated with reduced postoperative urinary retention. However, α-adrenergic receptor antagonists have been associated with intraoperative floppy iris syndrome (IFIS).

Receptor-mediated enhancement of beta adrenergic drug activity by ascorbate in vitro and in vivo. [PDF]

PLoS ONE, 2010
RATIONALE: Previous in vitro research demonstrated that ascorbate enhances potency and duration of activity of agonists binding to alpha 1 adrenergic and histamine receptors.

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

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

Involvement of Toll-Like Receptor 4 in Decreased Vasopressor Response Following Trauma/Hemorrhagic Shock

Critical Care Explorations, 2021
OBJECTIVES:. Refractory vascular failure due to the inability of vascular smooth muscle to respond to vasoconstrictors such as phenylephrine is a final common pathway for severe circulatory shock of any cause, including trauma/hemorrhagic shock ...

BIOMARKER IDENTIFICATION IN BREAST CANCER: BETA-ADRENERGIC RECEPTOR SIGNALING AND PATHWAYS TO THERAPEUTIC RESPONSE

Computational and Structural Biotechnology Journal, 2013
Recent preclinical studies have associated beta-adrenergic receptor (β-AR) signaling with breast cancer pathways such as progression and metastasis. These findings have been supported by clinical and epidemiological studies which examined the effect of ...

β-Adrenergic agonist and antagonist regulation of autophagy in HepG2 cells, primary mouse hepatocytes, and mouse liver. [PDF]

PLoS ONE, 2014
Autophagy recently has been shown to be involved in normal hepatic function and in pathological conditions such as non-alcoholic fatty liver disease. Adrenergic signalling also is an important regulator of hepatic metabolism and function.

β-Adrenergic receptors as immunomodulators in T cells: mechanisms of neuroimmune crosstalk and pathophysiological implications

Molecular Medicine
Regulation of T cell function by the sympathetic nervous system via β-adrenergic receptors is a pivotal research focus in neuroimmunology, with most studies centered on β2-adrenergic receptors. However, the roles of other subtypes remain unclear.

Adrenergic Autoantibody‐Induced Postural Tachycardia Syndrome in Rabbits

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Previous studies have demonstrated that functional autoantibodies to adrenergic receptors may be involved in the pathogenesis of postural tachycardia syndrome.

Role of β-adrenergic receptors in insulin resistance: Induction or protection?

Zagazig Journal of Pharmaceutical Sciences, 2021
β Adrenergic receptors, in particular β2 subtype, are key regulators of glucose homeostasis. Previous studies showed that activation of hepatic and adipose tissue β adrenergic receptors mediates insulin desensitizing effects.
