Nicotinic potentiation of frog retinotectal transmission in tectum layer F by α3β2, α4β2, α2β4, α6β2, or α7 acetylcholine receptor subtypes

Medicina, 2015
Objective: The aim of the study was to explore the effect of semi-specific antagonists and agonists of the nicotinic acetylcholine receptors on the paired-pulse facilitation and nicotinic tonic and phasic potentiation of the frog retinotectal synaptic ...

Alcohol and nicotinic acetylcholine receptors [PDF]

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

Discoveries and future significance of research into amyloid-beta/α7-containing nicotinic acetylcholine receptor (nAChR) interactions

Pharmacological Research, 2023
Initiated by findings that Alzheimer’s disease is associated with a profound loss of cholinergic markers in human brain, decades of studies have examined the interactions between specific subtypes of nicotinic acetylcholine receptors and amyloid-β ...

Heterogenous Cholinergic Nicotinic Receptors in the CNS

, 1988
Multiple nicotinic binding sites are found in mammalian brain. Several nicotinic agonists and antagonists have been used to characterize the nicotinic binding sites.

Loop B is a major structural component of the 5-HT3 receptor [PDF]

, 2008
The 5-HT3 receptor belongs to a family of therapeutically important neurotransmitter-gated receptors whose ligand binding sites are formed by the convergence of six peptide loops (A-F).

Identification of a domain which affects kinetics and antagonistic potency of clozapine at 5-HT3 receptors. [PDF]

, 2009
The widely used atypical antipsychotic clozapine is a potent competitive antagonist at 5-HT(3) receptors which may contribute to its unique psychopharmacological profile. Clozapine binds to 5-HT(3) receptors of various species.

DNA methylation and expression of MAPRE3 affect overall survival of early‐stage non‐small cell lung cancer patients

Molecular Oncology, EarlyView.
Both cg12821679MAPRE3 methylation and MAPRE3 expression are significantly associated with overall survival (OS) of non‐small cell lung cancer. Meanwhile, MAPRE3 expression significantly modified the effect of smoking cessation on OS. Smoking cessation benefits OS merely for patients with high MAPRE3 expression.

Unique nicotinic responses are present in distinct subtypes of mouse medial prefrontal layer V pyramidal neurons

Scientific Reports
The neurotransmitter acetylcholine supports goal-directed cognitive functions via activation of its nicotinic and muscarinic classes of receptors within the prefrontal cortex.
