Adrenergic receptors in the veins of the dog
European Journal of Pharmacology, 1969Abstract The actions of catecholamines and adrenergic blocking drugs on the veins of the dog (posterior vena cava, portal vein, femoral vein, lateral saphenous vein) were studied in vitro . In these experiments quantitative and qualitative differences were found. Superficial veins were more sensitive.

Molecular mechanisms of adrenergic receptors
Journal of Theoretical Biology, 1972Abstract Molecular models indicate that a simple complex of two pentapeptide segments of protein chain, plus one molecule of ATP and one of PGE, can construct a receptor for adrenaline that explains much of the SAR data on β-agonists and antagonists. A similar complex but without the PG can exert a cognate role for the α-receptor.

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 ...

The physiological effects of epinephrine and norepinephrine are caused by the interaction of these compounds with specific receptor molecules on the external surface of target cells. Since both epinephrine and norepinephrine are found in large quantities in the adrenal gland, these receptors are called adrenergic receptors.

Adrenergic receptors in the forehead microcirculation
Clinical Autonomic Research, 1996The presence of alpha- and beta-adrenoceptors in the forehead microcirculation was investigated in 49 healthy subjects. Local vascular responses to noradrenaline, isoprenaline and adrenergic antagonists, administered transcutaneously by iontophoresis, were monitored via laser Doppler flowmetry.

α1-Adrenergic receptors (ARs) exist in three distinct molecular subtypes: A, B, and D. They are expected to have distinct physiological roles in vivo, but this has been hard to prove because the pharmacological tools to distinguish the subtypes are limited and not always very selective. For this reason, several laboratories have turned to the knockout (
