Nicotinic Acetylcholine Receptor. Nicotinic acetylcholine receptors (AChRs) are members of the Cys-loop ligand-gated ion channel superfamily including the type 3 serotonin (5-HT), type A and C γ-aminobutyric acid (GABA), and glycine receptors (reviewed in Arias, ; Sine and Engel, ; Albuquerque et al., ).
The nicotinic acetylcholine receptor is a transmembrane allosteric protein that mediates transduction of chemoelectric signals throughout the nervous system by opening an intrinsic ionic channel. This rapid pore opening enables flow of Na +, K +, and, in several. The nicotinic acetylcholine receptor (nAChR) is a typical ion channel type receptor.
nAChR agonists such as Nicotinic acetylcholine receptor book evoke rapid excitatory responses in order of milliseconds. In addition to acute responses, sustained stimulation of nAChRs induces delayed cellular responses leading to neuroprotection via intracellular signal pathways probably triggered by Ca2+ influx.
The aim of this book is to summarize our understanding on the insect nicotinic acetylcholine receptors. This area of research received great impetus from the identification of the first subunit sequences to be used as neonicotinoid insecticide target sites.
Although a book of this nature can provide the details only of commonly published results, it is hoped that it may provide a useful guide.

Pages Insect pest control has continuously evolved from inorganics to botanicals, to chlo rinated hydrocarbons, to organophosphorus compounds and methylcarbamates, then synthetic pyrethroids and most recently synthetic nicotinoids as the major classes.
These insecticides allowed high standards of crop protection at minimal cost.

At first, this causes muscle weakness in the eye. The selective binding of six (S)-quinuclidine-triazoles and their (R)-enantiomers to nicotinic acetylcholine receptor (nAChR) subtypes α3β4 and α7, respectively, were analyzed by in silico docking to provide the insight into the molecular basis for the observed stereospecific subtype discrimination.
Homology modeling followed by molecular docking and molecular dynamics (MD) simulations. Nicotine is a chemical with multiple biological and neurological actions.
It is a natural alkaloid that mimics the effects of acetylcholine as a neurotransmitter. Nicotinic acetylcholine receptors are cholinergic receptors that activate ligand-gated ion channels in the plasma membranes of certain neurons and muscle cells.
These ion channels are opened by the binding of nicotine. The chapter briefly covers the history of protein and peptide neurotoxins in research on nicotinic acetylcholine receptors (nAChR). It all started with a great help of α-bungarotoxin and other similar α-neurotoxins from snake venoms in isolation from the Torpedo ray electric organ of the muscle-type nAChR as a first individual membrane receptor.

The nicotinic acetylcholine receptor: current views and future trends. [Francisco J Barrantes;] -- This book covers, in a well-organized and comprehensive manner, one of the fasted growing fields in the Molecular Neurosciences - that of the ligand-gated ion channels (LGIC).
Future trends, analyzed. Alcohol and nicotine are often co-abused. As many as 80–95% of alcoholics are also smokers, suggesting that ethanol and nicotine, the primary addictive component of tobacco smoke, may functionally interact in the central nervous system and/or share a common mechanism of action.
While nicotine initiates dependence by binding to and activating neuronal nicotinic acetylcholine receptors. Acetylcholine Nicotinic Receptors. Nicotinic receptors (nAChRs) are ligand-gated ion channels that modulate cell membrane potentials.
Each receptor is composed of pentameric combinations of subunits (α, β, δ, ε and γ). Nicotinic receptors are generally divided into three functional classes: muscle subunits (α1, β1, δ, ε, γ. search for books and compare prices.

2. Changeux et al. recently suggested that the SARS-CoV-2 spike (S) protein may interact with nicotinic acetylcholine receptors (nAChRs). Such interactions may be involved in pathology and infectivity. Here, we use molecular simulations of validated atomically detailed structures of nAChRs, and of the S protein, to investigate this "nicotinic hypothesis".Notably, α-conotoxins with carboxy-terminal (C-terminal) amidation are inhibitors of the pentameric nicotinic acetylcholine receptors (nAChRs), which are therapeutic targets for neurological diseases and disorders.
The (α3)2(β2)3 nAChR subunit arrangement comprises a pair of α3(+)β2(−) and β2(+)α3(−) interfaces, and a β2(+)β2(−) interface.
