The rate and extent of the agonist-dependent phosphorylation of beta 2-adrenergic receptors and rhodopsin by beta-adrenergic receptor kinase (beta ARK) are markedly enhanced on addition of G protein beta gamma subunits.

Biotechnology of β-adrenergic receptors [PDF]
Molecular Neurobiology, 1990 This article discusses the structural and functional features of a new family of membrane receptors including alpha-adrenergic and beta-adrenergic receptors for catecholamines, muscarinic receptors for acetylcholine, and receptors for histamine, dopamine, serotonin, and neuropeptides such as angiotensin.

Beta adrenergic receptors in the parathyroid glands
Naunyn-Schmiedeberg's Archives of Pharmacology, 1980The location of beta-adrenoceptors in human parathyroid gland was studied using an immunohistochemical method. Frozen sections of human parathyroid glands, taken from surgical samples, were treated with (-)-alprenolol, washed and exposed to (-)-alprenolol antibodies conjugated with fluorescent dyes.

The beta-adrenergic receptors of the myocardium play an important role in the regulation of heart function. The beta-adrenergic receptors belong to the family of G-protein coupled receptors. Three subtypes have been distinguished (beta1-, beta2-, and beta3-adrenoceptors).

β-Adrenergic receptors (β-ARs) have a key position not in to the overall regulation of cardiac function and have been shown to play an important role in various cardiac diseases and heart failure in particular. Beta adrenergic receptors (β-ARs) belong to the G protein-coupled receptor (GPCR) superfamily with widespread expression and cardiovascular ...

The catecholamines epinephrine and norepinephrine evoke specific beta-adrenergic responses in a variety of tissues.Examples of processes modulated by these agonists are chronotropic and inotropic cardiac responses, relaxation of smooth muscle, and lipolysis in adipose tissue.The facts that beta-adrenergic responses are limited to specific tissues and ...

Decreased beta-adrenergic receptor
Journal of Anesthesia, 1991We investigated alterations in the number and affinity of cardiac beta-adrenergic receptors during hemorrhagic shock. Forty male Wistar rats were divided into two groups: (1) a shock group (n=20), in which mean arterial blood pressure was decreased to 40\2-50 mmHg by bleeding and kept constant for 6 h; and (2) a control group (n=20), which underwent a ...

Autoantibodies and Beta-Adrenergic Receptors
New England Journal of Medicine, 1981IN recent years it has been recognized that autoantibodies to cell-surface receptors for hormones or neurohumoral agents can develop spontaneously and give rise to clinical states of altered endocrine or neuromuscular function. For example, autoantibodies to receptors for acetylcholine in skeletal muscle are associated with myasthenia gravis, those to ...

Beta adrenergic receptors in lymphocyte subpopulations
Journal of Allergy and Clinical Immunology, 1980To further evaluate the potential utility of lymphocyte beta adrenergic receptor assays in the study of receptor alterations in human disease, we studied highly purified populations of B and T lymphocytes in peripheral blood to see if differences existed in the concentration or affinity of beta adrenergic receptors and catecholamine-responsive cAMP ...
