Anti-alprenolol anti-idiotypic antibodies bind to beta-adrenergic receptors and modulate catecholamine-sensitive adenylate cyclase.
Rabbit antibodies induced against alprenolol, a potent beta-adrenergic antagonist, bind to other antagonists, and, with less avidity, to catecholamine agonists. Anti-idiotypic antibodies were raised against the anti-alprenolol immunoglobulins. The anti-idiotypic antibodies specifically bind and agglutinate turkey erythrocytes; this is not observed for human agglutinate turkey erythrocytes; this...
متن کاملAdrenergic Receptors
Neurons in the paraventricular nucleus (PVN) that project to the brainstem and spinal cord are important for autonomic regulation. The excitability of pre-autonomic PVN neurons is controlled by the noradrenergic input from the brainstem. In this study, we determined the role of " 2 adrenergic receptors in the regulation of excitatory and inhibitory synaptic inputs to spinally projecting PVN neu...
متن کاملAdrenergic Receptor Ligands
Yohimbine is a potent and relatively nonselective 2-adrenergic receptor (AR) antagonist. In an earlier report, we demonstrated that dimeric yohimbine analogs containing methylene and methylene-diglycine tethers were highly selective human 2C-AR ligands. Little work has been done to examine the role of the tether group or the absence of the second yohimbine pharmacophore on selectivity for human...

ion fluxes in these cells, we have now examined the possibility that the decrease in beta receptor number might be associated with concomitant changes in catecholamine-dependent potassium ion transport. Hypothyroid turkey erythrocytes display decreased sensitivity to isoproterenol-stimulated potassium influx. Half-maximal stimulation of potassium influx occurs at 9.2±+1.7 nM in hypothyroid cell...

Although quinidine is known to have antiadrenergic effects in the cardiovascular system, the precise mechanism by which it exerts these effects is not well defined. We asked whether quinidine binds directly to adrenergic receptors. Radioligand-binding assays were used to identify <*i -adrenergic receptors ([H]prazosin-binding sites) on membranes prepared from rat heart and kidney, a2-adrenergic...
