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

open access: yesToxics, 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]

open access: yesActa 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

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

open access: yesMedicina, 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.

open access: yesPLoS 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

The Novel, Nicotinic Alpha7 Receptor Partial Agonist, BMS-933043, Improves Cognition and Sensory Processing in Preclinical Models of Schizophrenia. [PDF]

open access: yesPLoS ONE, 2016
The development of alpha7 nicotinic acetylcholine receptor agonists is considered a promising approach for the treatment of cognitive symptoms in schizophrenia patients. In the present studies we characterized the novel agent, (2R)-N-(6-(1H-imidazol-1-yl)

Nicotinic acetylcholine receptors and cancer

open access: yesBiomedical Reports, 2016
Nicotine, the primary addictive constituent of cigarettes, is believed to contribute to cancer promotion and progression through the activation of nicotinic acetylcholine receptors (nAChRs), which are membrane ligand-gated cation channels. nAChRs activation can be triggered by the neurotransmitter Ach, or certain other biological compounds, such as ...

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

open access: yesPLoS 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.

New insight into the tick neuronal nicotinic acetylcholine receptors: from molecular to pharmacological studies

open access: yesTicks and Tick-Borne Diseases
ACh is known to be an excitatory neurotransmitter in the central nervous system of several arthropod species. Nicotinic acetylcholine receptors are involved in rapid neurotransmission and are the target of compounds used as acaricides.

Activation of a nicotinic acetylcholine receptor

open access: yesBiophysical 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).
