acetylcholine receptor

[ə‚sed·əl ′kō‚lēn ri‚sep·tər]
(cell and molecular biology)
A receptor in the membranes of certain cell structures, such as synapses or the neuromuscular junction, to which the transmitter substance acetylcholine binds. Nicotinic acetylcholine receptors are gated ion channels that open in response to acetylcholine, leading to an increase in membrane conductance; muscarinic acetylcholine receptors are G-protein-linked receptors inducing membrane ion channel changes or intracellular processes such as smooth muscle contraction.

The drug's action on central muscarinic cholinergic receptors could be responsible for its effect on mood.
Varenicline-Nicotinic Receptor Partial Agonist: Varenicline is a nicotinic receptor partial agonist acting mainly on the [alpha][beta][beta]2 subtype of the nicotinic cholinergic receptor. As a partial agonist, it both reduces cravings for smoking and decreases the pleasurable effects of cigarettes and other tobacco products.
Tobacco and alcohol use may be related at least partially because both nicotine and alcohol affect brain nicotinic cholinergic receptors (Collins 1990; Little 2000).
The cerebellar changes in the later stages of development, however, could not have been the result of cholinesterase inhibition because the cerebellum is not innervated with cholinergic receptors like the forebrain is (Crumpton et al.

The reduction in presynaptic activity was not compensated by up-regulation of cholinergic receptors, as we found no significant alteration of [m.sub.2]AChR binding.
With the present work in developing sea urchins, chlorpyrifos elicited developmental anomalies similar to those seen previously for cholinergic receptor agonists (55) such as nicotine (47).
The inhibition of these enzymes increases the availability of Ach, which in turn can stimulate cholinergic receptors producing both nicotinic and muscarinic effects in the organism such as muscle contractions and secretions in many glands (5).
Selective serotonin reuptake inhibitors (SSRIs) are mainly selective for 5-hydroxytryptamine (5-HT) receptor, but they have extremely weak effect on a[sub]1 adrenergic or cholinergic receptors. Therefore, they are usually considered to have little effect on IOP.
The company, which was founded by PureTech Health, focuses on muscarinic cholinergic receptors for the treatment of psychosis and cognitive impairment across central nervous system disorders, including schizophrenia and Alzheimer's disease, as well as neuropathic pain.
Glycopyrronium blocks sweat production "by inhibiting the interaction between acetylcholine and the cholinergic receptors responsible for sweat gland activation," the company said in a February press release.
