Synaptic transmission as a cooperative phenomenon in confined systems [PDF]

Condens. Matter Phys., 2017, vol. 20, No. 1, 13804, 2017
In this review paper, the theory of synaptic transmission (ST) was developed and discussed. We used the hypothesis of isomorphism between: (a) the cooperative behavior of mediators --- acetylcholine molecules (ACh) and cholinoreceptors in a synaptic cleft with binding into mediator-receptor (AChR) complexes, (b) the critical phenomena in confined ...

Chemical Proteomics Reveals Human Off‐Targets of Fluoroquinolone Induced Mitochondrial Toxicity

Angewandte Chemie International Edition, EarlyView.
A schematic overview of the adverse effects of Ciprofloxacin related to mitochondrial toxicity. AIFM1 plays a role in the MIA40‐mediated import into the IMS and oxidative folding of nuclear‐encoded proteins, including ETC complexes I and IV subunits. Ciprofloxacin disrupts the IMS import machinery, impairing ETC function.

Acetylcholine Attenuates Hydrogen Peroxide-Induced Intracellular Calcium Dyshomeostasis Through Both Muscarinic and Nicotinic Receptors in Cardiomyocytes

Cellular Physiology and Biochemistry, 2016
Background/Aims: Oxidative stress induced intracellular Ca2+ overload plays an important role in the pathophysiology of several heart diseases. Acetylcholine (ACh) has been shown to suppress reactive oxygen species generation during oxidative stress ...

Mechanisms of Chronic Nicotine Treatment–Induced Enhancement of the Sensitivity of Cortical Neurons to the Neuroprotective Effect of Donepezil in Cortical Neurons

Journal of Pharmacological Sciences, 2010
We have previously shown that chronic donepezil treatment induces nicotinic acetylcholine receptor up-regulation and enhances the sensitivity of the neurons to the neuroprotective effect of donepezil. Further analyses revealed that the nicotinic receptor

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

Nature 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

Cholinergic receptor alterations in the cerebral cortex of spinal cord injured rat

Biochemistry and Biophysics Reports, 2017
Many areas of the cerebral cortex process sensory information or coordinate motor output necessary for control of movement. Disturbances in cortical cholinergic system can affect locomotor coordination.

Discovery of the First Neurotransmitter Receptor: The Acetylcholine Nicotinic Receptor

Biomolecules, 2020
The concept of pharmacological receptor was proposed at the turn of the 20th century but it took almost 70 years before the first receptor for a neurotransmitter was isolated and identified as a protein.

Modelling organophosphate intoxication in C. elegans highlights nicotinic acetylcholine receptor determinants that mitigate poisoning.

PLoS ONE, 2023
Organophosphate intoxication via acetylcholinesterase inhibition executes neurotoxicity via hyper stimulation of acetylcholine receptors. Here, we use the organophosphate paraoxon-ethyl to treat C.

Deciphering the skeletal interoceptive circuitry to control bone homeostasis

BMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

Cholinergic switch between two types of slow waves in cerebral cortex [PDF]

Cerebral Cortex 2019, 2018
Sleep slow waves are known to participate in memory consolidation, yet slow waves occurring under anesthesia present no positive effects on memory. Here, we shed light onto this paradox, based on a combination of extracellular recordings in vivo, in vitro, and computational models.
