Functional Characterization of a Novel Class of Morantel-Sensitive Acetylcholine Receptors in Nematodes. [PDF]
PLoS Pathogens, 2015 Acetylcholine receptors are pentameric ligand-gated channels involved in excitatory neuro-transmission in both vertebrates and invertebrates. In nematodes, they represent major targets for cholinergic agonist or antagonist anthelmintic drugs. Despite the

A physical model of nicotinic ACh receptor kinetics [PDF]
arXiv, 2008 We present a new approach to nicotinic receptor kinetics and a new model explaining random variabilities in the duration of open events. The model gives new interpretation on brief and long receptor openings and predicts (for two identical binding sites) the presence of three components in the open time distribution: two brief and a long.

Activation of a nicotinic acetylcholine receptor
Biophysical Journal, 1984 We studied activation of the nicotinic acetylcholine (ACh) receptor on cells of a mouse clonal muscle cell line (BC3H1). We analyzed single-channel currents through outside-out patches elicited with various concentrations of acetylcholine (ACh), carbamylcholine (Carb) and suberyldicholine (Sub).

Localization of muscarinic acetylcholine receptor 2 to the intestinal crypt stem cell compartment
Data in Brief, 2017 The data presented in this article are related to the research article entitled “Distribution of muscarinic acetylcholine receptor subtypes in the murine small intestine” (E.D. Muise, N. Gandotra, J.J. Tackett, M.C. Bamdad, R.A. Cowles, 2016) [1].

The Channel Capacity of Channelrhodopsin and Other Intensity-Driven Signal Transduction Receptors [PDF]
arXiv, 2018 Biological systems transduce signals from their surroundings through a myriad of pathways. In this paper, we describe signal transduction as a communication system: the signal transduction receptor acts as the receiver in this system, and can be modeled as a finite-state Markov chain with transition rates governed by the input signal.

Pharmacological Research, 2023 Initiated by findings that Alzheimer’s disease is associated with a profound loss of cholinergic markers in human brain, decades of studies have examined the interactions between specific subtypes of nicotinic acetylcholine receptors and amyloid-β ...

Untangling direct and domain-mediated interactions between nicotinic acetylcholine receptors in DHA-rich membranes [PDF]
arXiv, 2019 At the neuromuscular junction (NMJ), the nicotinic acetylcholine receptor (nAChR) self-associates to give rise to rapid muscle movement. While lipid domains have maintained nAChR aggregates in-vitro, their specific roles in nAChR clustering are currently unknown. In the present study, we carried out coarse-grained molecular dynamics simulations (CG-MD)

On the excitation of action potentials by protons and its potential implications for cholinergic transmission [PDF]
, 2014 One of the most conserved mechanisms for transmission of a nerve pulse across a synapse relies on acetylcholine. Ever since the Nobel-prize winning works of Dale and Loewi, it has been assumed that acetylcholine - subsequent to its action on a postsynaptic cell - is split into inactive by-products by acetylcholinesterase.

Cellular Physiology and Biochemistry, 2016 Background/Aims: Oxidative stress induced intracellular Ca2+ overload plays an important role in the pathophysiology of several heart diseases. Acetylcholine (ACh) has been shown to suppress reactive oxygen species generation during oxidative stress ...
