Nicotinic Receptor – an overview | ScienceDirect Topics

Nicotinic acetylcholine receptors (nAChRs) are cholinergic receptors that form ligand-gated ion channels in the plasma membranes of certain neurons and on the postsynaptic side of the neuromuscular junction. As ionotropic receptors, nAChRs are directly linked to ion channels and do not use second messengers.

Prucalopride increased EFS-induced tritium and [3H]-acetylcholine efflux in whole tissue and in isolated CM strips. All effects of prucalopride were antagonized by the selective 5-HT4 receptor antagonist GR113808. The results obtained indicate the presence of excitatory 5-HT4 receptors on cholinergic nerves within the CM of human colon.

Nicotinic Receptor – Pathway Medicine

Nictotinic Receptors bind acetylcholine and are located in the CNS, autonomic ganglia, and at the neuromuscular junction. They take their name from the fact that they specifically bind Nicotine with only mild affinity for Muscarine. These receptors are ion channels and acetylocholine binding leads to direct opening of sodium channels and thus depolarization of the neuron.
