Modelling organophosphate intoxication in C. elegans highlights nicotinic acetylcholine receptor determinants that mitigate poisoning.

open access: yesPLoS ONE, 2023
Organophosphate intoxication via acetylcholinesterase inhibition executes neurotoxicity via hyper stimulation of acetylcholine receptors. Here, we use the organophosphate paraoxon-ethyl to treat C.

Neural signatures of cognitive flexibility and reward sensitivity following nicotinic receptor stimulation in dependent smokers : a randomized trial [PDF]

open access: yes, 2017
IMPORTANCE Withdrawal from nicotine is an important contributor to smoking relapse. Understanding how reward-based decision making is affected by abstinence and by pharmacotherapies such as nicotine replacement therapy and varenicline tartrate may aid ...

Cytotoxicity of 19 Pesticides in Rainbow Trout Gill, Liver, and Intestinal Cell Lines

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract The rainbow trout gill cell line (RTgill‐W1), via test guideline 249 of the Organisation for Economic Co‐operation and Development, has been established as a promising New Approach Methodology, although to advance confidence in the method more case studies are needed that: 1) expand our understanding of applicability domains (chemicals with ...

Variations in “Functional Site” Residues and Classification of Three-Finger Neurotoxins in Snake Venoms

open access: yesToxins
Three-finger toxins (3FTxs) are the largest group of nonenzymatic toxins found in snake venoms. Among them, neurotoxins that target nicotinic acetylcholine receptors are the most well-studied ligands.

Structural principles of distinct assemblies of the human α4β2 nicotinic receptor

open access: yesNature, 2018
Fast chemical communication in the nervous system is mediated by neurotransmitter-gated ion channels. The prototypical member of this class of cell surface receptors is the cation-selective nicotinic acetylcholine receptor.

Lateral Habenula contribution in Nicotine addiction : focus on Dopamine, GABA and Serotonin Interactions [PDF]

open access: yes, 2011
Compelling evidence has shown a pivotal role of dopaminergic function in drug addiction. Recently, the Habenula (Hb) has attracted a great deal of attention as another target for nicotine in the brain because of its role in regulating dopamine (DA ...

Characterization of nicotine acetylcholine receptor subunits in the cockroach Periplaneta americana mushroom bodies reveals a strong expression of β1 subunit: involvement in nicotine-induced currents [PDF]

open access: yes, 2016
Nicotinic acetylcholine receptors are ligand-gated ion channels expressed in many insect structures, such as mushroom bodies, in which they play a central role.

Vanillin Modulates the Sedative Effect of Diazepam, Possibly Through GABAergic Interaction Pathways in Thiopental Sodium‐Induced Sleeping Mice

open access: yesFood Safety and Health, EarlyView.
Vanillin showed moderate sedative and modulatory synergistic activities on diazepam in thiopental sodium‐induced sleeping mice. These effects are implicated with GABAergic intervention. ABSTRACT Insomnia is a common sleep disorder affecting approximately 10% of adults.

Rates and Equilibria for a Photoisomerizable Antagonist at the Acetylcholine Receptor of Electrophorus Electroplaques [PDF]

open access: yes, 1985
Voltage-jump and light-flash experiments have been performed on isolated Electrophorus electroplaques exposed simultaneously to nicotinic agonists and to the photoisomerizable compound 2,2'-bis-[α-(trimethylammonium)methyl]-azobenzene (2BQ).
