Alpha receptor agonists are substances that activate the sympathetic nervous system by stimulation of alpha receptors, similar to the effects of epinephrine and norepinephrine. Alpha receptors are ...

The Vaughan Williams classification system divides these agents based on their mechanisms of action at the cell membrane ― ion channels and sympathetic receptors ― and their effects on the ...

They also identified that the activation of CRH receptors, specifically CRH receptor ... Then, the team investigated the sympathetic innervation of the liver and demonstrated that sympathetic ...

Within this receptor family, the structural and functional ... in synaptic signaling in both the neuromuscular junction and sympathetic ganglia, there is a scarcity of reports which detail ...

The overall goal of medication is to dampen the sympathetic outflow or act as the parasympathetic system. Thus, sedatives, opiate receptor agonists, beta-blockers, and CNS depressants have been used.

"Our next step is to determine which cells with the alpha 2 receptor are receiving signals from the sympathetic nervous system and play a role in C. difficile-mediated disease," Petri said.

Ephedrine sulfate is a sympathomimetic amine that directly acts as an agonist at α-and ß-adrenergic receptors and indirectly causes the release of norepinephrine from sympathetic neurons.
