Jin Y, Wang Q, Wang Y, Liu M, Sun A, Geng Z, Lin Y, Li X.
PMID: 28955138
Shanghai Arch Psychiatry. 2017 Aug 25;29(4):191-199. doi: 10.11919/j.issn.1002-0829.217044.

BACKGROUND: Previous clinical trials of α7-nicotinic acetylcholine receptor agonists (α7-nAChR agonists) showed mixed results in treating the cognitive and negative symptoms of schizophrenia.AIMS: To assess the efficacy and safety of α7-nAChR agonists in treating the cognitive and negative symptoms...

Characterization of Nicotinic Acetylcholine Receptors Expressed by Cells of the SH-SY5Y Human Neuroblastoma Clonal Line.

Molecular and cellular neurosciences

Lukas RJ, Norman SA, Lucero L.
PMID: 19912902
Mol Cell Neurosci. 1993 Feb;4(1):1-12. doi: 10.1006/mcne.1993.1001.

Radioligand binding studies show that cells of the SH-SY5Y human neuroblastoma clonal line express a single class of neuronal/nicotinic alpha-bungarotoxin binding sites (nBgtS). These sites are defined by their ability to bind radioiodinated alpha-bungarotoxin (Bgt) with high affinity (K(D)...

Canonical and Novel Non-Canonical Cholinergic Agonists Inhibit ATP-Induced Release of Monocytic Interleukin-1β via Different Combinations of Nicotinic Acetylcholine Receptor Subunits α7, α9 and α10.

Frontiers in cellular neuroscience

Zakrzewicz A, Richter K, Agné A, Wilker S, Siebers K, Fink B, Krasteva-Christ G, Althaus M, Padberg W, Hone AJ, McIntosh JM, Grau V.
PMID: 28725182
Front Cell Neurosci. 2017 Jul 05;11:189. doi: 10.3389/fncel.2017.00189. eCollection 2017.

Recently, we discovered a cholinergic mechanism that inhibits the adenosine triphosphate (ATP)-dependent release of interleukin-1β (IL-1β) by human monocytes via nicotinic acetylcholine receptors (nAChRs) composed of α7, α9 and/or α10 subunits. Furthermore, we identified phosphocholine (PC) and dipalmitoylphosphatidylcholine (DPPC)...

Acetylcholine receptor subunit and P-glycoprotein transcription patterns in levamisole-susceptible and -resistant Haemonchus contortus.

Sarai RS, Kopp SR, Coleman GT, Kotze AC.

Int J Parasitol Drugs Drug Resist. 2013 Feb 01;3:51-8. doi: 10.1016/j.ijpddr.2013.01.002. eCollection 2013 Dec.

The mechanism of resistance to the anthelmintic levamisole in parasitic nematodes is poorly understood, although there is some evidence implicating changes in expression of nicotinic acetylcholine receptor (nAChR) subunit genes. Hence, in order to define levamisole resistance mechanisms in...

Emerging Pharmacological Properties of Cholinergic Synaptic Transmission: Comparison between Mammalian and Insect Synaptic and Extrasynaptic Nicotinic Receptors.

Current neuropharmacology

Thany SH, Tricoire-Leignel H.
PMID: 22654728
Curr Neuropharmacol. 2011 Dec;9(4):706-14. doi: 10.2174/157015911798376343.

Acetylcholine (ACh) is probably the oldest signalling neurotransmitter which appeared in evolution before the nervous system. It is present in bacteria, algae, protozoa and plants. In insects and mammals it is involved in cell-to-cell communications in various neuronal and...

Monoclonal antibodies against ?-bungarotoxin.

Neurochemistry international

Quik M, Geertsen S, Kenigsberg RL, Cuello AC.
PMID: 20504554
Neurochem Int. 1990;16(2):163-71. doi: 10.1016/0197-0186(90)90084-7.

Hybridomas secreting monoclonal antibodies against ?-bungarotoxin were produced from the fusions of mice lymphocytes from hyperimmune animals with two mice myeloma cell lines ((NSI/1 or Sp2/0). Several anti-?-bungarotoxin monoclonal antibodies were derived and characterized. One of these (spB57) belonged...

In vivo pharmacological profile of substituted (3-pyridyl)-2-phenylisoxazolidine analogues of nicotine as novel antinociceptives.

Research in pharmaceutical sciences

Sethi N, Bhatti R, Ishar MP.
PMID: 25598800
Res Pharm Sci. 2014 Jan-Feb;9(1):59-67.

Nicotinic ligands have been studied as novel therapeutic interventions in pain therapeutics since a long time. Several nicotinic agonists have been withdrawn from later stages of clinical trials due to lack of efficacy or narrow therapeutic window. These have...

Insights into the mechanism by which atropine inhibits myopia: evidence against cholinergic hyperactivity and modulation of dopamine release.

British journal of pharmacology

Thomson K, Kelly T, Karouta C, Morgan I, Ashby R.
PMID: 34302355
Br J Pharmacol. 2021 Nov;178(22):4501-4517. doi: 10.1111/bph.15629. Epub 2021 Oct 10.

BACKGROUND AND PURPOSE: The ability of the muscarinic cholinergic antagonist atropine to inhibit myopia development in humans and animal models would suggest that cholinergic hyperactivity may underlie myopic growth. To test this, we investigated whether cholinergic agonists accelerate ocular...

Utilization of computer processed high definition video imaging for measuring motility of microscopic nematode stages on a quantitative scale: "The Worminator".

A major hindrance to evaluating nematode populations for anthelmintic resistance, as well as for screening existing drugs, new compounds, or bioactive plant extracts for anthelmintic properties, is the lack of an efficient, objective, and reproducible in vitro assay that...

Density of α4β2* nAChR on the surface of neurons is modulated by chronic antagonist exposure.

Pharmacology research & perspectives

Zambrano CA, Short CA, Salamander RM, Grady SR, Marks MJ.
PMID: 25729578
Pharmacol Res Perspect. 2015 Mar;3(2):e00111. doi: 10.1002/prp2.111.

The expression of high-affinity α4β2* nicotinic acetylcholine receptors (nAChR) increases following chronic exposure to nicotinic agonists. While, nAChR antagonists can also produce upregulation, these changes are often less pronounced than achieved with agonists. It is unknown if nAChR agonists...
