Nicotinic acetylcholine receptors. [PDF]

British Journal of Pharmacology, 2018
This themed section of the British Journal of Pharmacology is the product of a conference that focussed on nicotinic ACh receptors (nAChRs) that was held on the Greek island of Crete from 7 to 11 May 2017. 'Nicotinic acetylcholine receptors 2017' was the

Mechanosensitivity of nicotinic receptors [PDF]

Pflügers Archiv - European Journal of Physiology, 2012
Nicotinic acetylcholine receptors (nAChRs) are heteropentameric ligand-gated ion channels that mediate excitatory neurotransmission at the neuromuscular junction (NMJ) and other peripheral and central synapses. At the NMJ, acetylcholine receptors (AChRs) are constantly exposed to mechanical stress resulting from muscle contraction.

Nicotinic Receptors in Neurodegeneration [PDF]

Current Neuropharmacology, 2013
Many studies have focused on expanding our knowledge of the structure and diversity of peripheral and central nicotinic receptors. Nicotinic acetylcholine receptors (nAChRs) are members of the Cys-loop superfamily of pentameric ligand-gated ion channels, which include GABA (A and C), serotonin, and glycine receptors.

Up-regulation of Nicotinic Receptors by Nicotine Varies with Receptor Subtype [PDF]

Journal of Biological Chemistry, 2008
Recent evidence suggests that in addition to alpha4beta2 and alpha3-containing nicotinic receptors, alpha6-containing receptors are present in midbrain dopaminergic neurons and involved in the nicotine reward pathway. Using heterologous expression, we found that alpha6beta2, like alpha3beta2 and alpha4beta2 receptors, formed high affinity epibatidine ...

Curiouser and Curiouser: The Macrocyclic Lactone, Abamectin, Is also a Potent Inhibitor of Pyrantel/Tribendimidine Nicotinic Acetylcholine Receptors of Gastro-Intestinal Worms. [PDF]

PLoS ONE, 2016
Nematode parasites may be controlled with drugs, but their regular application has given rise to concerns about the development of resistance. Drug combinations may be more effective than single drugs and delay the onset of resistance.

Nicotine and nicotinic receptors in the circadian system

Psychoneuroendocrinology, 1998
Considerable data support a role for cholinergic influences on the circadian system. The extent to which these influences are mediated by nicotinic acetylcholine receptors (nAChRs) has been controversial, as have the specific actions of nicotine and acetylcholine in the suprachiasmatic nucleus (SCN) of the hypothalamus.

Cloning and characterization of the hamster and guinea pig nicotinic acid receptors

Journal of Lipid Research, 2007
In this study, we present the identification and characterization of hamster and guinea pig nicotinic acid receptors. The hamster receptor shares ∼80–90% identity with the nucleotide and amino acid sequences of human, mouse, and rat receptors. The guinea

Differing time dependencies of object recognition memory impairments produced by nicotinic and muscarinic cholinergic antagonism in perirhinal cortex [PDF]

, 2011
The roles of muscarinic and nicotinic cholinergic receptors in perirhinal cortex in object recognition memory were compared. Rats' discrimination of a novel object preference test (NOP) test was measured after either systemic or local infusion into the ...

Signaling of nicotinic acetylcholine receptors in mononuclear phagocytes

Pharmacological Research, 2023
Nicotinic acetylcholine receptors are not only expressed by the nervous system and at the neuro-muscular junction but also by mononuclear phagocytes, which belong to the innate immune system.

Acetylcholine release in mouse hippocampal CA1 preferentially activates inhibitory-selective interneurons via alpha4 beta2* nicotinic receptor activation

Frontiers in Cellular Neuroscience, 2015
Acetylcholine (ACh) release onto nicotinic receptors directly activates subsets of inhibitory interneurons in hippocampal CA1. However, the specific interneurons activated and their effect on the hippocampal network is not completely understood ...
