This release, which is independent of central sympathetic activity and from extracellular calcium, occurs in two steps: First, noradrenaline escapes from its intracellular storage vesicles and accumulates in the cytoplasm of the neuron. In a second, rate-limiting step, noradrenaline is

Treatment with the partial agonist pindolol did not cause up-regulation of β-receptors, and did not block ischemia-induced externalization..In the second part of this study, we have begun to examine post-receptor events in a rat mod

In acute myocardial ischemia, cardiac β-adrenoceptors increase; this increase is — at least in early acute myocardial ischemia — accompanied by an increased β-adrenocept

Both the G.-linked GTPase-activity and the binding of [γ-.S]GTP are reduced by 25–30% without any loss of the total protein. Stimulatory effects prevail at the G-protein level since in the early period of ischemia the st

Selective β-adrenergic receptor activation demonstrated that both β.- and β.-adrenergic receptors elicit dilation of large coronary arteries, and that the vasodilation was direct, i.e., it was not mediated by increases in coronary blood flow. Biochemical characterization of adrenergic subtype d

These effects could not be attributed to baroreceptor unloading. In dogs studied under resting conditions with norepinephrine infusion to produce an increas
