Frontiers in Neural Circuits, 2022 The neuromodulator acetylcholine (ACh) plays an important role in arousal, attention, vigilance, learning and memory. ACh is released during different behavioural states and affects the brain microcircuit by regulating neuronal and synaptic properties ...

Simultaneous Presence of Acetylcholine Receptor and Muscle Specific Tyrosine Kinase Antibodies in Myasthenia Gravis [PDF]
International Journal of Basic Science in Medicine, 2019 Myasthenia gravis (MG) is known as an autoimmune disorder which affects transmission in neuromuscular junction. The serologic tests used for diagnosis include acetylcholine receptor and muscle specific receptor tyrosine kinase antibodies.

Pharmaceuticals, 2023 Neuropathic pain affects about 7–8% of the population, and its management still poses challenges with unmet needs. Over the past decades, researchers have explored the cholinergic system (muscarinic and nicotinic acetylcholine receptors: mAChR and nAChR)

A potential cost of evolving epibatidine resistance in poison frogs
BMC Biology, 2023 Background Some dendrobatid poison frogs sequester the toxin epibatidine as a defense against predators. We previously identified an amino acid substitution (S108C) at a highly conserved site in a nicotinic acetylcholine receptor β2 subunit of ...

Acetylcholine and Acetylcholine Receptors in Taste Receptor Cells [PDF]
Chemical Senses, 2005 Neuroactive substances play important roles as transmitters and neuromodulators. Although many of these substances and/or their receptors are known to be present in taste receptor cells and nerve fibers innervating taste buds, physiological functions of these substances are not well understood (Nagai et al., 1996).

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 fourth in a series of triennial international meetings that have provided a regular forum for ...

A novel labeling approach identifies three stability levels of acetylcholine receptors in the mouse neuromuscular junction in vivo. [PDF]
PLoS ONE, 2011 BACKGROUND: The turnover of acetylcholine receptors at the neuromuscular junction is regulated in an activity-dependent manner. Upon denervation and under various other pathological conditions, receptor half-life is decreased.

Sequence of age-associated changes to the mouse neuromuscular junction and the protective effects of voluntary exercise. [PDF]
PLoS ONE, 2013 Loss of connections between motor neurons and skeletal muscle fibers contribute to motor impairment in old age, but the sequence of age-associated changes that precede loss of the neuromuscular synapse remains uncertain.

Loss of Acetylcholine Signaling Reduces Cell Clearance Deficiencies in Caenorhabditis elegans. [PDF]
PLoS ONE, 2016 The ability to eliminate undesired cells by apoptosis is a key mechanism to maintain organismal health and homeostasis. Failure to clear apoptotic cells efficiently can cause autoimmune diseases in mammals.
