Psychological stress induces an increase in cholinergic enteric neuromuscular pathways mediated by glucocorticoid receptors

open access: yesFrontiers in Neuroscience, 2023
IntroductionRepeated acute stress (RASt) is known to be associated with gastrointestinal dysfunctions. However, the mechanisms underlying these effects have not yet been fully understood.

Investigation of the Possible Pharmacologically Active Forms of the Nicotinic Acetylcholine Receptor Agonist Anabaseine

open access: yesMarine Drugs, 2019
Three major forms of the nicotinic agonist toxin anabaseine (cyclic iminium, cyclic imine and the monocationic open-chain ammonium-ketone) co-exist in almost equal concentrations at physiological pH.

Impaired muscarinic modulation of the rat prelimbic cortex in neuropathic pain is sexually dimorphic and associated with cold allodynia

open access: yesFrontiers in Cellular Neuroscience, 2023
Cholinergic modulation of the brain cortex is critical for cognitive processes, and altered cholinergic modulation of the prefrontal cortex is emerging as an important mechanism of neuropathic pain.

Eyeing up the Future of the Pupillary Light Reflex in Neurodiagnostics

open access: yesDiagnostics, 2018
The pupillary light reflex (PLR) describes the constriction and subsequent dilation of the pupil in response to light as a result of the antagonistic actions of the iris sphincter and dilator muscles.

Nerve Growth Factor: A Dual Activator of Noradrenergic and Cholinergic Systems of the Rat Ovary

open access: yesFrontiers in Endocrinology, 2021
The functioning of the ovary is influenced by the autonomic system (sympathetic and cholinergic intraovarian system) which contributes to the regulation of steroid secretion, follicular development, and ovulation.

Ciliomotor circuitry underlying whole-body coordination of ciliary activity in the Platynereis larva

open access: yeseLife, 2017
Ciliated surfaces harbouring synchronously beating cilia can generate fluid flow or drive locomotion. In ciliary swimmers, ciliary beating, arrests, and changes in beat frequency are often coordinated across extended or discontinuous surfaces.

A Microbioassay for Acetylcholine.

open access: yesExperimental Biology and Medicine, 1961
SummaryA microbioassay for acetylcholine is described in which a solution containing acetylcholine is microperfused onto the endplate area of a chronically denervated skeletal muscle fiber. The endpoint, a brief tetanus, can be produced by application of as little as 0.15 μl of a solution which contains acetylcholine chloride at a concentration of 2.5 ×

C. elegans neurons have functional dendritic spines

open access: yeseLife, 2019
Dendritic spines are specialized postsynaptic structures that transduce presynaptic signals, are regulated by neural activity and correlated with learning and memory. Most studies of spine function have focused on the mammalian nervous system.

Acetylcholine From Tuft Cells: The Updated Insights Beyond Its Immune and Chemosensory Functions

open access: yesFrontiers in Cell and Developmental Biology, 2020
Tuft cells, rare solitary chemosensory cells, are distributed in mucosal epithelium throughout mammalian organs. Their nomenclatures are various in different organs and may be confused with other similar cells.
