The muscarinic acetylcholine receptor M 2, also known as the cholinergic receptor, muscarinic 2, is a muscarinic acetylcholine receptor that in humans is encoded by the CHRM2 gene. [5] Multiple alternatively spliced transcript variants have been described for this gene. [5] It is G i-coupled, reducing intracellular levels of cAMP.
Atropine - an antagonist. Muscarinic acetylcholine receptors, or mAChRs, are acetylcholine receptors that form G protein-coupled receptor complexes in the cell membranes of certain neurons [1] and other cells. They play several roles, including acting as the main end-receptor stimulated by acetylcholine released from postganglionic fibers.
Nicotinic acetylcholine receptors (nAChR, also known as "ionotropic" acetylcholine receptors) are particularly responsive to nicotine. The nicotine ACh receptor is also a Na +, K + and Ca 2+ ion channel. Muscarinic acetylcholine receptors (mAChR, also known as "metabotropic" acetylcholine receptors) are particularly responsive to muscarine.
Diabetes. The muscarinic M 3 receptor regulates insulin secretion from the pancreas [7] and are an important target for understanding the mechanisms of type 2 diabetes mellitus. Some antipsychotic drugs that are prescribed to treat schizophrenia and bipolar disorder (such as olanzapine and clozapine) have a high risk of diabetes side-effects.
The muscarinic acetylcholine receptor M 1, also known as the cholinergic receptor, muscarinic 1, is a muscarinic receptor that in humans is encoded by the CHRM1 gene. [5] It is localized to 11q13. [5] This receptor is found mediating slow EPSP at the ganglion in the postganglionic nerve, [6] is common in exocrine glands and in the CNS. [7] [8]
Cholinergic crisis. Cholinergic crisis. Other names. Cholinergic toxicity, cholinergic poisoning, SLUDGE syndrome. A cholinergic crisis is an over-stimulation at a neuromuscular junction due to an excess of acetylcholine (ACh), [1] as a result of the inactivity of the AChE enzyme, which normally breaks down acetylcholine.
Aceclidine, for glaucoma. Arecoline, an alkaloid present in the Betel nut. Pilocarpine is a drug that acts as a muscarinic receptor agonist that is used to treat glaucoma. Cevimeline (AF102B) (Evoxac®) is a muscarinic agonist that is a Food and Drug Administration (FDA)- approved drug and used for the management of dry mouth in Sjögren's ...
Cholinergic. Cholinergic agents are compounds which mimic the action of acetylcholine and/or butyrylcholine. [1] In general, the word "choline" describes the various quaternary ammonium salts containing the N, N, N -trimethylethanolammonium cation. Found in most animal tissues, choline is a primary component of the neurotransmitter ...
