Investigation of varenicline and tropisetron in latent inhibition and novel object recognition in mice [PDF]

Scientific Reports
There is currently no treatment for cognitive-impairment associated with schizophrenia (CIAS). Animal and human studies suggest that nicotinic cholinergic agonists and 5-HT3 antagonists have potential therapeutic benefits.

A Systematic Review on Drugs Acting as Nicotinic Acetylcholine Receptor Agonists in the Treatment of Dementia

Cells
Acetylcholine signaling is attenuated in early Alzheimer’s disease (AD) and other dementias. A significant reduction in the expression of nicotinic acetylcholine receptors (nAChRs) in the brain of AD patients has also been reported in several molecular ...

Fluorescence activation mechanism and imaging of drug permeation with new sensors for smoking-cessation ligands

eLife, 2022
Nicotinic partial agonists provide an accepted aid for smoking cessation and thus contribute to decreasing tobacco-related disease. Improved drugs constitute a continued area of study. However, there remains no reductionist method to examine the cellular

Nicotinic acetylcholine receptor agonists attenuate septic acute kidney injury in mice by suppressing inflammation and proteasome activity. [PDF]

PLoS ONE, 2012
Sepsis is one of the leading causes of acute kidney injury (AKI). Septic patients who develop acute kidney injury (AKI) are at increased risk of death. To date there is no effective treatment for AKI or septic AKI.

Acute activation, desensitization and smoldering activation of human acetylcholine receptors. [PDF]

PLoS ONE, 2013
The behavioral effects of nicotine and other nicotinic agonists are mediated by AChRs in the brain. The relative contribution of acute activation versus chronic desensitization of AChRs is unknown. Sustained "smoldering activation" occurs over a range of

Silent agonists for α7 nicotinic acetylcholine receptors

Pharmacological Research, 2023
We discuss models for the activation and desensitization of α7 nicotinic acetylcholine receptors (nAChRs) and the effects of efficacious type II positive allosteric modulators (PAMs) that destabilize α7 desensitized states.

Recent Advances in the Discovery of Nicotinic Acetylcholine Receptor Allosteric Modulators

Molecules, 2023
Positive allosteric modulators (PAMs), negative allosteric modulators (NAMs), silent agonists, allosteric activating PAMs and neutral or silent allosteric modulators are compounds capable of modulating the nicotinic receptor by interacting at allosteric ...

Ingestion of A Common Plant’s Leaves Leads to Acute Respiratory Arrest and Paralysis: A Case Report

Clinical Practice and Cases in Emergency Medicine, 2020
Background: Nicotiana glauca is a plant known to cause acute toxicity upon ingestion or dermal exposure due to the nicotinic alkaloid, anabasine. Nicotinic alkaloids cause toxicity by acting as agonists on nicotinic-type acetylcholine receptors (nAChRs).

Cholinergic anti-inflammatory pathway and COVID-19 [PDF]

BioImpacts, 2022
The cholinergic anti-inflammatory pathway (CAP) first described by Wang et al, 2003 has contemporary interest arising from the COVID-19 pandemic. While tobacco smoking has been considered an aggravating factor in the severity of COVID-19 infections, it ...

Advances in small molecule selective ligands for heteromeric nicotinic acetylcholine receptors

Pharmacological Research, 2023
The study of nicotinic acetylcholine receptors (nAChRs) has significantly progressed in the last decade, due to a) the improved techniques available for structural studies; b) the identification of ligands interacting at orthosteric and allosteric ...
