Venom-Derived Neurotoxins Targeting Nicotinic Acetylcholine Receptors

Molecules, 2021
Acetylcholine was the first neurotransmitter described. The receptors targeted by acetylcholine are found within organisms spanning different phyla and position themselves as very attractive targets for predation, as well as for defense. Venoms of snakes

Characterization of nAChRs in Nematostella vectensis supports neuronal and non-neuronal roles in the cnidarian–bilaterian common ancestor

EvoDevo, 2019
Background Nicotinic and muscarinic acetylcholine receptors likely evolved in the cnidarian–bilaterian common ancestor. Both receptor families are best known for their role at chemical synapses in bilaterian animals, but they also have described roles as

Toxic Effect of Cigarette Smoke on Brainstem Nicotinic Receptor Expression: Primary Cause of Sudden Unexplained Perinatal Death

Toxics, 2018
Among the neurotoxicants contained in tobacco smoke, if absorbed during pregnancy, nicotine significantly affects α7-nicotinic acetylcholine receptors, which play essential roles in the development of the brainstem regions receiving cholinergic ...

Understanding of nicotinic acetylcholine receptors [PDF]

Acta Pharmacologica Sinica, 2009
Cigarette smoking is a major public health problem and has been identified as the second-most prevalent cause of death in the world. China, a country with a population of 1.3 billion, is the world's largest producer and consumer of tobacco. It estimates that there are 0.35 billion cigarette smokers in China, which bears a large proportion of the deaths

Embedded Cholesterol in the Nicotinic Acetylcholine Receptor [PDF]

Biophysical Journal, 2008
The nicotinic acetylcholine receptor (nAChR) is a cation-selective channel central to both neuronal and muscular processes and is considered the prototype for ligand-gated ion channels, motivating a structural determination effort that spanned several decades [Unwin N (2005) Refined structure of the nicotinic acetylcholine receptor

Nicotinic potentiation of frog retinotectal transmission in tectum layer F by α3β2, α4β2, α2β4, α6β2, or α7 acetylcholine receptor subtypes

Medicina, 2015
Objective: The aim of the study was to explore the effect of semi-specific antagonists and agonists of the nicotinic acetylcholine receptors on the paired-pulse facilitation and nicotinic tonic and phasic potentiation of the frog retinotectal synaptic ...

Inhibition of nicotinic acetylcholine receptors, a novel facet in the pleiotropic activities of snake venom phospholipases A2.

PLoS ONE, 2014
Phospholipases A2 represent the most abundant family of snake venom proteins. They manifest an array of biological activities, which is constantly expanding. We have recently shown that a protein bitanarin, isolated from the venom of the puff adder Bitis

Concomitant release of ventral tegmental acetylcholine and accumbal dopamine by ghrelin in rats. [PDF]

PLoS ONE, 2012
Ghrelin, an orexigenic peptide, regulates energy balance specifically via hypothalamic circuits. Growing evidence suggest that ghrelin increases the incentive value of motivated behaviours via activation of the cholinergic-dopaminergic reward link.
