Alcohol and nicotinic acetylcholine receptors

QScience Connect, 2013
Background The frequent co-abuse of alcohol and tobacco may suggest that they share some common neurological mechanisms. For example, nicotine acts on Nicotinic acetylcholine receptors (nAChRs) in the brain to release dopamine to sustain addiction. Might nAChRs be entwined with alcohol?

Translational Medicine in Alzheimer's Disease: The Journey of Donanemab From Discovery to Clinical Application

Chronic Diseases and Translational Medicine, EarlyView.
Donanemab, approved by the U.S. FDA in July 2024, targets amyloid plaques in the brain to treat Alzheimer's disease in patients with mild cognitive impairment or mild dementia. ABSTRACT Substantial research has been conducted to identify an efficient treatment for Alzheimer's disease (AD).

Structures of highly flexible intracellular domain of human α7 nicotinic acetylcholine receptor

Nature Communications, 2022
The intracellular domain (ICD) of Cys-loop receptors mediates many of their functions, but no complete structure of a Cys-loop receptor ICD is available to date.

A physical model of nicotinic ACh receptor kinetics [PDF]

arXiv, 2008
We present a new approach to nicotinic receptor kinetics and a new model explaining random variabilities in the duration of open events. The model gives new interpretation on brief and long receptor openings and predicts (for two identical binding sites) the presence of three components in the open time distribution: two brief and a long.

Simultaneous Modeling of In Vivo and In Vitro Effects of Nondepolarizing Neuromuscular Blocking Drugs [PDF]

arXiv, 2023
Nondepolarizing neuromuscular blocking drugs (NDNBs) are clinically used to produce muscle relaxation during general anesthesia. This paper explores a suitable model structure to simultaneously describe in vivo and in vitro effects of three clinically used NDNBs, cisatracurium, vecuronium, and rocuronium. In particular, it is discussed how to reconcile

Structure of nicotinic acetylcholine receptors

Current Opinion in Neurobiology, 1993
Nicotinic acetylcholine (ACh) receptors convert the binding of ACh into the opening of a cation-conducting channel. New information about the regions of the receptor most immediately involved in its function, namely the ACh-binding sites, the gate and the channel, has come from two approaches.

Cytotoxicity of 19 Pesticides in Rainbow Trout Gill, Liver, and Intestinal Cell Lines

Environmental Toxicology and Chemistry, EarlyView.
Abstract The rainbow trout gill cell line (RTgill‐W1), via test guideline 249 of the Organisation for Economic Co‐operation and Development, has been established as a promising New Approach Methodology, although to advance confidence in the method more case studies are needed that: 1) expand our understanding of applicability domains (chemicals with ...

Untangling direct and domain-mediated interactions between nicotinic acetylcholine receptors in DHA-rich membranes [PDF]

arXiv, 2019
At the neuromuscular junction (NMJ), the nicotinic acetylcholine receptor (nAChR) self-associates to give rise to rapid muscle movement. While lipid domains have maintained nAChR aggregates in-vitro, their specific roles in nAChR clustering are currently unknown. In the present study, we carried out coarse-grained molecular dynamics simulations (CG-MD)

Abnormal response to chronic social defeat stress and fear extinction in a mouse model of Lynx2-based cholinergic dysregulation

Frontiers in Neuroscience
Nicotinic receptor signaling is influential in modulating appropriate responses to salient stimuli within a complex environment. The cholinergic neurotransmitter system drives attention to salient stimuli such as stressors, and aids in orchestrating the ...
