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

, 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).

Phosphocholine-Modified Lipooligosaccharides of Haemophilus influenzae Inhibit ATP-Induced IL-1beta Release by Pulmonary Epithelial Cells [PDF]

, 2018
Phosphocholine-modified bacterial cell wall components are virulence factors enabling immune evasion and permanent colonization of the mammalian host, by mechanisms that are poorly understood.

Neuronal nicotinic acetylcholine receptors: neuroplastic changes underlying alcohol and nicotine addictions

Frontiers in Molecular Neuroscience, 2012
Addictive drugs can activate systems involved in normal reward-related learning, creating long-lasting memories of the drug's reinforcing effects and the environmental cues surrounding the experience.

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

, 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 ...

Mechanisms of Chronic Nicotine Treatment–Induced Enhancement of the Sensitivity of Cortical Neurons to the Neuroprotective Effect of Donepezil in Cortical Neurons

Journal of Pharmacological Sciences, 2010
We have previously shown that chronic donepezil treatment induces nicotinic acetylcholine receptor up-regulation and enhances the sensitivity of the neurons to the neuroprotective effect of donepezil. Further analyses revealed that the nicotinic receptor

Glutamatergic Synapse Formation is Promoted by α7-Containing Nicotinic Acetylcholine Receptors

Journal of Neuroscience, 2012
Glutamate is the primary excitatory transmitter in adult brain, acting through synapses on dendritic spines and shafts. Early in development, however, when glutamatergic synapses are only beginning to form, nicotinic cholinergic excitation is already ...

Weizmannia coagulans XY2 Mitigates Copper Neurotoxicity via Gut–Brain Axis Modulation of Tryptophan Metabolism and Oxidative‐Inflammatory Crosstalk

iMetaOmics, EarlyView.
Copper interferes with tryptophan metabolism and 5‐HT levels by modulating intestinal flora. Intestinal barrier breakdown and inflammatory response trigger nerve damage under copper exposure. W. coagulans XY2 alleviates copper‐induced neurotoxicity by targeting a multi‐dimensional “tryptophan metabolism‐antioxidant defense‐gut‐brain axis” network.

Pretreatment of the cockroach cercal afferent/giant interneuron synapses with nicotinoids and neonicotinoids differently affects acetylcholine and nicotine-induced ganglionic depolarizations [PDF]

, 2013
We have recently demonstrated that neonicotinoid insecticides were able to act as agonists of postsynaptic nicotinic acetylcholine receptors (nAChRs) expressed at the synapse between the cercal nerve XI and the giant interneurons, in the sixth abdominal ...

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

Toxins
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.
