Reduced levels of Aβ 40 and Aβ 42 in brains of smoking controls and Alzheimer's patients

Neurobiology of Disease, 2004
The effects of nicotine on levels of Aβ 40 and Aβ 42 and nicotinic receptor binding sites were studied in brains from nonsmoking and smoking patients with Alzheimer's disease (AD) and aged-matched controls.

The GSK3-NRF2 Axis in Suicide

Psychiatry International, 2021
Mutations in the genes coding for tryptophan-hydrolase-2 and the scaffold protein FKBP5 are associated with an increased risk of suicide. The mutation in both cases enhances the enzymatic activity of glycogen synthase kinase-3 (GSK3).

Nicotinic receptor agonists as neuroprotective/neurotrophic drugs. Progress in molecular mechanisms [PDF]

, 2006
In the present work we reviewed recent advances concerning neuroprotective/neurotrophic effects of acute or chronic nicotine exposure, and the signalling pathways mediating these effects, including mechanisms implicated in nicotine addiction and nAChR ...

Agonist efficiency links binding and gating in a nicotinic receptor

eLife, 2023
Receptors signal by switching between resting (C) and active (O) shapes (‘gating’) under the influence of agonists. The receptor’s maximum response depends on the difference in agonist binding energy, O minus C.

Actions of Agonists, Fipronil and Ivermectin on the Predominant In Vivo Splice and Edit Variant (RDLbd, I/V) of the Drosophila GABA Receptor Expressed in Xenopus laevis Oocytes [PDF]

, 2014
Ionotropic GABA receptors are the targets for several classes of insecticides. One of the most widely-studied insect GABA receptors is RDL (resistance to dieldrin), originally isolated from Drosophila melanogaster.

Chemical Profiling, In Silico and In Vitro Studies to Identify Potential CDK2 and mTOR Inhibitor From Selaginella inaequalifolia (Hook. & Grev.) Spring Ethanolic Extracts

Chemistry &Biodiversity, EarlyView.
ABSTRACT The current study is aimed to reveal the phytoprofile of Selaginella inaequalifolia (Hook. & Grev.) Spring using GC–MS and predict the drug properties, toxicity, biological properties of S. inaequalifolia ethanolic extracts (SiEE) using in silico methods and in vitro toxicity assays, namely, MTT and BSLB assay.

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).

The Pathway to Proof‐of‐Concept for BNC210, a Negative Allosteric Modulator of the Alpha‐7 Nicotinic Acetylcholine Receptor (nAChR), for Treatment of Psychiatric Disease

Clinical Pharmacology in Drug Development, EarlyView.
Abstract BNC210 is an investigational small molecule selective negative allosteric modulator of the alpha‐7 nicotinic acetylcholine receptor (α7 nAChR). It is an anxiolytic compound with a novel mechanism of action. In a series of Phase 1 clinical trials in healthy volunteers, psychometric test batteries showed that BNC210 did not cause attention ...

Subtype-Selective Peptide and Protein Neurotoxic Inhibitors of Nicotinic Acetylcholine Receptors Enhance Proliferation of Patient-Derived Glioblastoma Cell Lines

Toxins
Glioblastoma multiforme (GBM) is the most aggressive type of brain cancer, with a poor prognosis. GBM cells, which develop in the environment of neural tissue, often exploit neurotransmitters and their receptors to promote their own growth and invasion ...
