Muscarinic and Nicotinic Contribution to Contrast Sensitivity of Macaque Area V1 Neurons

Frontiers in Neural Circuits, 2017
Acetylcholine is a neuromodulator that shapes information processing in different cortical and subcortical areas. Cell type and location specific cholinergic receptor distributions suggest that acetylcholine in macaque striate cortex should boost feed ...

Nicotinic alpha 7 receptor agonists EVP-6124 and BMS-933043, attenuate scopolamine-induced deficits in visuo-spatial paired associates learning. [PDF]

PLoS ONE, 2017
Agonists at the nicotinic acetylcholine alpha 7 receptor (nAChR α7) subtype have the potential to treat cognitive deficits in patients with Alzheimer's disease (AD) or schizophrenia.

Structurally similar allosteric modulators of α7 nicotinic acetylcholine receptors exhibit five distinct pharmacological effects. [PDF]

, 2015
Activation of nicotinic acetylcholine receptors (nAChRs) is associated with the binding of agonists such as acetylcholine to an extracellular site that is located at the interface between two adjacent receptor subunits.

Hydroxycarboxylic Acid Receptor 2 Mediates β‐hydroxybutyrate's Antiseizure Effect in Mice

Annals of Neurology, EarlyView.
A Objective The ketogenic diet, a high‐fat, low‐carbohydrate regimen, is often used to treat drug‐resistant seizures and is being studied for Alzheimer's disease and other neuropsychiatric disorders. However, its mechanism of action remains unclear. β‐hydroxybutyrate, a primary circulating ketone body produced by the ketogenic diet, may mediate its ...

Identification of critical residues in loop E in the 5-HT(3AS)R binding site [PDF]

, 2002
BACKGROUND: The serotonin type 3 receptor (5-HT(3)R) is a member of a superfamily of ligand gated ion channels. All members of this family share a large degree of sequence homology and presumably significant structural similarity.

CB2R agonist prevents nicotine induced lung fibrosis

Experimental Lung Research, 2018
Nicotine stimulates fibroblast proliferation while increasing inflammation and fibrosis of tissues. The cannabinoid receptor 1 (CB1R) is mainly located in the CNS, while cannabinoid receptor 2 (CB2R) is located in the immune cells within the body. CB2R regulates inflammatory processes and fibroblast function.We investigated the impact of CB2R agonist ...

Activation of muscle nicotinic acetylcholine receptor channels by nicotinic and muscarinic agonists [PDF]

British Journal of Pharmacology, 1999
The dose‐response parameters of recombinant mouse adult neuromuscular acetylcholine receptor channels (nAChR) activated by carbamylcholine, nicotine, muscarine and oxotremorine were measured. Rate constants for agonist association and dissociation, and channel opening and closing, were estimated from single‐channel kinetic analysis.

Drug‐Induced Raynaud's Phenomenon and Underlying Mechanism: A Disproportionality Analysis From the World Health Organization Pharmacovigilance Database

Arthritis &Rheumatology, EarlyView.
Objectives The aim of this study is to generate hypotheses about unknown drugs associated with the onset or worsening of Raynaud's phenomenon (RP) and to explore their potential pathophysiologic mechanisms through a mixed disproportionality/clustering analysis from the World Health Organization (WHO) pharmacovigilance database.

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.
