Nicotinic acetylcholine receptors [PDF]
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 fourth in a series of triennial international meetings that have provided a regular forum for ...

Mechanosensitivity of nicotinic receptors [PDF]
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]
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]
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 ...

Nicotine and nicotinic receptors in the circadian system
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.

Signaling of nicotinic acetylcholine receptors in mononuclear phagocytes
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.

Live-Cell Imaging of Single Receptor Composition Using Zero-Mode Waveguide Nanostructures [PDF]
We exploit the optical and spatial features of subwavelength nanostructures to examine individual receptors on the plasma membrane of living cells. Receptors were sequestered in portions of the membrane projected into zero-mode waveguides.

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 ...

The Hair Cell α9α10 Nicotinic Acetylcholine Receptor: Odd Cousin in an Old Family
Nicotinic acetylcholine receptors (nAChRs) are a subfamily of pentameric ligand-gated ion channels with members identified in most eumetazoan clades.

Differential Contribution of Subunit Interfaces to α 9 α 10 Nicotinic Acetylcholine Receptor Function [PDF]
Nicotinic acetylcholine receptors can be assembled from either homomeric or heteromeric pentameric subunit combinations. At the interface of the extracellular domains of adjacent subunits lies the acetylcholine binding site, composed of a principal ...
