Functional alteration of the beta-adrenergic receptor during desensitization of mammalian adenylate cyclase by beta-agonists. [PDF]

Proceedings of the National Academy of Sciences, 1984
Exposure of several mammalian cell lines to isoproterenol resulted in a desensitization of the beta-adrenergic receptor-adenylate cyclase system in membranes isolated from the cells. Under the experimental conditions chosen, desensitization was accompanied by a minimal loss of beta-receptors.

LBMON186 Beta-agonist Profiling Reveals Novel Biased Signaling Phenotypes For The Beta 2-adrenergic Receptor With Implications In The Treatment Of Asthma

Journal of the Endocrine Society, 2022
Abstract Asthma involves chronic airway inflammation and airway smooth muscle (ASM) cell contraction. Treatment include agonists of the beta 2-AR, a GPCR that induces the Gs/cAMP pathway leading to ASM relaxation. These agonists can also promote severe side effects which have been correlated with beta-arrestins (barr) activation ...

Beta-Adrenergic Agonists

Pharmaceuticals, 2010
Inhaled β2-adrenoceptor (β2-AR) agonists are considered essential bronchodilator drugs in the treatment of bronchial asthma, both as symptoms-relievers and, in combination with inhaled corticosteroids, as disease-controllers.

Inhibition of the lipolytic action of beta-adrenergic agonists in human adipocytes by alpha-adrenergic agonists.

Journal of Lipid Research, 1981
The aim of this study was to define the role of the alpha-adrenergic receptor in the regulation of lipolysis by human adipocytes. Glycerol production by isolated human adipocytes was stimulated by the pure beta-adrenergic agonist isoproterenol in a dose ...

Beta-adrenergic receptor antagonism is proinflammatory and exacerbates neuroinflammation in a mouse model of Alzheimer's Disease

Neurobiology of Disease, 2020
Adrenergic systems regulate both cognitive function and immune function. The primary source of adrenergic signaling in the brain is norepinephrine (NE) neurons of the locus coeruleus (LC), which are vulnerable to age-related degeneration and are one of ...

The (--)[3H]dihydroalprenolol binding to rat adipocyte membranes: an explanation of curvilinear Scatchard plots and implications for quantitation of beta-adrenergic sites

Journal of Lipid Research, 1982
In rat adipocyte membranes, both beta-adrenergic agonists and beta-adrenergic antagonists competed with (--)[3H]dihydroalprenolol for high affinity (KD 2-4 nM) and low capacity binding sites.

Inverted Variant of Takotsubo Syndrome Caused by Inhaled Adrenergic Beta-2 Agonists

European Journal of Case Reports in Internal Medicine, 2018
Takotsubo syndrome (TS) is an acute and reversible clinical syndrome characterized by transient hypokinesis of the left ventricular (LV) apex. Variant forms of LV dysfunction have been reported, including inverted Takotsubo syndrome (ITS), which ...

Trafficking of β2-adrenergic receptors: insulin and β-agonists regulate internalization by distinct cytoskeletal pathways [PDF]

Journal of Cell Science, 2004
Insulin and β-adrenergic agonists stimulate a rapid phosphorylation and sequestration of the β2-adrenergic receptors (β2ARs). Although the expectation was that a common pathway would be involved in the trafficking of the β2AR in response to either hormone, studies reported herein show the existence of unique cytoskeletal requirements for ...
