The alpha-3 beta-4 nicotinic receptor, also known as the α3β4 receptor and the ganglion-type nicotinic receptor, [1] is a type of nicotinic acetylcholine receptor, consisting of α3 and β4 subunits.
The adrenergic receptors or adrenoceptors are a class of G protein-coupled receptors that are targets of many catecholamines like norepinephrine (noradrenaline) and epinephrine (adrenaline) produced by the body, but also many medications like beta blockers, beta-2 (β 2) antagonists and alpha-2 (α 2) agonists, which are used to treat high ...
Nicotinic receptors get their name from nicotine which does not stimulate the muscarinic acetylcholine receptors but selectively binds to the nicotinic receptors instead. [3] [4] [5] The muscarinic acetylcholine receptor likewise gets its name from a chemical that selectively attaches to that receptor—muscarine. [6]

The alpha-4 beta-2 nicotinic receptor, also known as the α4β2 receptor, is a type of nicotinic acetylcholine receptor implicated in learning, [1] consisting of α4 and β2 subunits. [2] It is located in the brain, where activation yields post-and presynaptic excitation, [2] mainly by increased Na + and K + permeability.
The alpha-3 beta-2 nicotinic receptor, also known as the α3β2 receptor, is a type of nicotinic acetylcholine receptor, consisting of α3 and β2 subunits. It occurs alongside the more common α3β4 nicotinic receptor in autonomic ganglia, and as an facilitatory presynaptic autoreceptor at the neuromuscular junction (NMJ). At the NMJ, it is ...
Neuronal acetylcholine receptor subunit alpha-4, also known as nAChRα4, is a protein that in humans is encoded by the CHRNA4 gene. [5] [6] The protein encoded by this gene is a subunit of certain nicotinic acetylcholine receptors (nAChR). Alpha4-containing nAChRs (specifically the alpha4beta2 subtype) appear to play a crucial role in the ...
Alpha-adrenergic agonists are a class of sympathomimetic agents that selectively stimulates alpha adrenergic receptors. The alpha-adrenergic receptor has two subclasses α 1 and α 2. Alpha 2 receptors are associated with sympatholytic properties. Alpha-adrenergic agonists have the opposite function of alpha blockers.
