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

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

Structure of nicotinic acetylcholine receptors

open access: yesCurrent 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.

Structural model of nicotinic acetylcholine receptor isotypes bound to acetylcholine and nicotine [PDF]

open access: yesBMC Structural Biology, 2002
Nicotine is a psychoactive drug presenting a diverse array of biological activities, some positive, such as enhancement of cognitive performances, others negative, such as addiction liability. Ligands that discriminate between the different isotypes of nicotinic acetylcholine receptors (nAChRs) could present improved pharmacology and toxicity profile ...

Trihexyphenidyl rescues the deficit in dopamine neurotransmission in a mouse model of DYT1 dystonia

open access: yesNeurobiology of Disease, 2019
Trihexyphenidyl, a nonselective muscarinic receptor antagonist, is the small molecule drug of choice for the treatment of DYT1 dystonia, but it is poorly tolerated due to significant side effects.

Nicotinic acetylcholine receptors as targets for antidepressants [PDF]

open access: yesMolecular Psychiatry, 2002
While the monoamine deficiency hypothesis of depression is still most commonly used to explain the actions of antidepressant drugs, a growing body of evidence has accumulated that is not adequately explained by the hypothesis. This article draws attention to contributions from another apparently common pharmacological property of antidepressant ...

The Role of Nicotinic Receptors on Ca2+ Signaling in Bovine Chromaffin Cells

open access: yesCurrent Issues in Molecular Biology
Chromaffin cells have been used as a physiological model to understand neurosecretion in mammals for many years. Nicotinic receptors located in the cells’ membrane are stimulated by acetylcholine, and they participate in the exocytosis of chromaffin ...

Origin of acetylcholine antagonism in ELIC, a bacterial pentameric ligand-gated ion channel

open access: yesCommunications Biology, 2022
A structural and functional study of the prokaryotic ligand-gated ion channel, ELIC, provides insight into the origin of agonism and antagonism at nicotinic acetylcholine receptors.

Acetylcholine and cholinergic receptors

open access: yesBrain and Neuroscience Advances, 2019
This review provides a distillate of the advances in knowledge about the neurotransmitter functions of acetylcholine over the 50-year period between 1967 and 2017, together with incremental information about the cognate nicotinic and muscarinic ...

"Warming yang and invigorating qi" acupuncture alters acetylcholine receptor expression in the neuromuscular junction of rats with experimental autoimmune myasthenia gravis

open access: yesNeural Regeneration Research, 2016
Myasthenia gravis is an autoimmune disorder in which antibodies have been shown to form against the nicotinic acetylcholine nicotinic postsynaptic receptors located at the neuromuscular junction.

Activation of spinal alpha-7 nicotinic acetylcholine receptor shortens the duration of remifentanil-induced postoperative hyperalgesia by upregulating KCC2 in the spinal dorsal horn in rats

open access: yesMolecular Pain, 2017
Background Accumulating evidence has shown that the signal from spinal brain-derived neurotrophic factor/tyrosine receptor kinase B-K + -Cl − cotransporter-2 plays a critical role in the process of pain hypersensitivity.
