Alzheimer’s Disease as a Membrane Disorder: Spatial Cross-Talk Among Beta-Amyloid Peptides, Nicotinic Acetylcholine Receptors and Lipid Rafts [PDF]
Frontiers in Cellular Neuroscience, 2019 Biological membranes show lateral and transverse asymmetric lipid distribution. Cholesterol (Chol) localizes in both hemilayers, but in the external one it is mostly condensed in lipid-ordered microdomains (raft domains), together with saturated ...

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 ...

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.
