Expression of the α7 nicotinic acetylcholine receptor in human lung cells

open access: yesRespiratory Research, 2005
Background We and others have shown that one of the mechanisms of growth regulation of small cell lung cancer cell lines and cultured pulmonary neuroendocrine cells is by the binding of agonists to the α7 neuronal nicotinic acetylcholine receptor.

Conformational dynamics of a nicotinic receptor neurotransmitter site

open access: yeseLife
Agonists enhance receptor activity by providing net-favorable binding energy to active over resting conformations, with efficiency (η) linking binding energy to gating.

Acetylcholine receptor based chemogenetics engineered for neuronal inhibition and seizure control assessed in mice

open access: yesNature Communications
Epilepsy is a prevalent disorder involving neuronal network hyperexcitability, yet existing therapeutic strategies often fail to provide optimal patient outcomes. Chemogenetic approaches, where exogenous receptors are expressed in defined brain areas and

Nicotinic acetylcholine receptors: Therapeutic targets for novel ligands to treat pain and inflammation

open access: yesPharmacological Research, 2023
Nicotinic acetylcholine receptors (nAChRs) have been historically defined as ligand-gated ion channels and function as such in the central and peripheral nervous systems. Recently, however, non-ionic signaling mechanisms via nAChRs have been demonstrated

Neurotransmitter regulation of neural development: acetylcholine and nicotinic receptors

open access: yesAnais da Academia Brasileira de Ciências, 2002
Several neurotransmitter systems have been related to developmental processes during the past decade. In this review, we discuss the evidence that the nicotinic acetylcholine receptors could have an additional function during development that may be ...

The Novel, Nicotinic Alpha7 Receptor Partial Agonist, BMS-933043, Improves Cognition and Sensory Processing in Preclinical Models of Schizophrenia. [PDF]

open access: yesPLoS ONE, 2016
The development of alpha7 nicotinic acetylcholine receptor agonists is considered a promising approach for the treatment of cognitive symptoms in schizophrenia patients. In the present studies we characterized the novel agent, (2R)-N-(6-(1H-imidazol-1-yl)

Contrasting properties of α7-selective orthosteric and allosteric agonists examined on native nicotinic acetylcholine receptors. [PDF]

open access: yesPLoS ONE, 2013
Subtype-selective ligands are important tools for the pharmacological characterisation of neurotransmitter receptors. This is particularly the case for nicotinic acetylcholine receptors (nAChRs), given the heterogeneity of their subunit composition.

Antinociceptive property of the nicotinic agonist AG-4 in rodents [PDF]

open access: yesDrug Development Research, 1997
AG-4 has been characterized as a nicotinic agonist by binding (K i = 26 ± 1.4 μM) and in vitro functional assays. The antinociceptive effect of AG-4 was examined in mice and rats, using the hot plate, abdominal constriction, and paw-pressure tests.

Minimal Structural Changes Determine Full and Partial Nicotinic Receptor Agonist Activity for Nicotine Analogues

open access: yesMolecules, 2019
Neuronal α4β2 nicotinic acetylcholine receptors (nAChRs) are ligand-gated ion channels (LGIC) that have been implicated in nicotine addiction, reward, cognition, pain disorders, anxiety, and depression.

The nicotinic modulation of pain

open access: yesPakistan Journal of Pharmaceutical Sciences, 2020
Pain is a physiological unpleasant sensation that associated with actual or potential tissue damage and affects the major part of human population. Numerous modulatory system control pain through a complex process.
