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

Neuronal Nicotinic Acetylcholine Receptor Modulators from Cone Snails
Marine Drugs, 2018 Marine cone snails are a large family of gastropods that have evolved highly potent venoms for predation and defense. The cone snail venom has exceptional molecular diversity in neuropharmacologically active compounds, targeting a range of receptors, ion

Structural model of nicotinic acetylcholine receptor isotypes bound to acetylcholine and nicotine [PDF]
BMC Structural Biology, 2002 Nicotine is a psychoactive drug presenting a diverse array of biological activities, some positive, such as enhancement of cognitive performances, others negative, such as addiction liability. Ligands that discriminate between the different isotypes of nicotinic acetylcholine receptors (nAChRs) could present improved pharmacology and toxicity profile ...

Nicotinic α7 acetylcholine receptor-mediated currents are not modulated by the tryptophan metabolite kynurenic acid in adult hippocampal interneurons [PDF]
, 2012 The tryptophan metabolite, kynurenic acid (KYNA), is classically known to be an antagonist of ionotropic glutamate receptors. Within the last decade several reports have been published suggesting that KYNA also blocks nicotinic acetylcholine receptors (nAChRs) containing the \alpha7 subunit (\alpha7*).

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations
Advanced Functional Materials, EarlyView.Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.

A factor graph EM algorithm for inference of kinetic microstates from patch clamp measurements [PDF]
arXiv, 2021 We derive a factor graph EM (FGEM) algorithm, a technique that permits combined parameter estimation and statistical inference, to determine hidden kinetic microstates from patch clamp measurements. Using the cystic fibrosis transmembrane conductance regulator (CFTR) and nicotinic acetylcholine receptor (nAChR) as examples, we perform {\em Monte Carlo}

Conformation of acetylcholine bound to the nicotinic acetylcholine receptor. [PDF]
Proceedings of the National Academy of Sciences, 1988 We report here the biologically active conformation of acetylcholine when bound to the high-affinity state of the receptor from Torpedo californica. The acetylcholine conformation was determined in the free and bound states by proton NMR two-dimensional nuclear Overhauser effects. In agreement with x-ray crystallographic data, acetylcholine in solution

Animal Models and Experimental Medicine, EarlyView.KLF4 (Krüppel‐like factor 4) plays a protective role in blood–brain barrier (BBB). KLF4 plays an ambiguous role in the central nervous system. KLF4 in the BBB endothelial cells could be a potential target for Alzheimer's disease. Abstract Alzheimer's disease is the most prevalent chronic neurodegenerative disorder worldwide, with no sufficient cure ...
