Influence of the mucosa on the excitability of myenteric neurons
Neuroscience, 1997 Intracellular microelectrodes were used to examine the active and passive membrane properties of neurons in the myenteric plexus of the guinea-pig small intestine. Neurons of two types were examined: S neurons, which have prominent fast excitatory postsynaptic potentials and in which action potentials are not followed by long-lasting ...

Effects of H2O2 at rat myenteric neurones in culture [PDF]
European Journal of Pharmacology, 2009 Oxidants, produced e.g. during inflammation, alter gastrointestinal functions finally leading to diarrhoea and/or tissue damage. There is only scarce information about the action of oxidants on enteric neurones, which play a central role in the regulation of many gastrointestinal processes. Therefore, the effect of an oxidant, H(2)O(2), on cultured rat

Quantification of the neurons of myenteric plexus of the bat molossus rufus [PDF]
Pesquisa Veterinária Brasileira: There are no studies that characterize the enteric nervous system (ENS) bats. The organization and density of myenteric neurons may vary according to the animal species, as well as the segment of the digestive tube considered.

Atrophic Myenteric and Submucosal Neurons Are Observed in Parkinson’s Disease [PDF]
Parkinson's Disease, 2019 Aim. Parkinson’s disease is often accompanied by gastrointestinal symptoms, especially constipation. Microscopic studies of the enteric nervous system and enteric neuropathy have often been performed by immunostaining in the myenteric plexa. The aim of the present study was to examine whether pathologic changes could be identified by conventional ...

Regional differences in the number and type of myenteric neurons in the descending colon of rats [PDF]
Arquivos de Neuro-Psiquiatria, 2003 The purpose of this study was to analyze the neuronal density of the myenteric plexus of the intermediate and antimesocolic regions of the descending colon of rats.

Specific localization of β-Arrestin2 in myenteric plexus of mouse gastrointestinal tract. [PDF]
PLoS ONE, 2014 β-arrestin2 is a key molecule involved in signaling and internalization of activated G protein-coupled receptors including µ-opioid receptors (MOR). Previously we have shown that decreased expression of β-arrestin2 upon chronic morphine is associated ...

No neuronal loss, but alterations of the GDNF system in asymptomatic diverticulosis.
PLoS ONE, 2017 BackgroundGlial cell line-derived neurotrophic factor (GDNF) is a potent neurotrophic factor known to promote the survival and maintenance of neurons not only in the developing but also in the adult enteric nervous system. As diverticular disease (DD) is

Sympathetic Pathways Target Cholinergic Neurons in the Human Colonic Myenteric Plexus
Frontiers in Neuroscience, 2022 BackgroundThe sympathetic nervous system inhibits human colonic motility largely by effects on enteric neurons. Noradrenergic axons, which branch extensively in the myenteric plexus, are integral to this modulatory role, but whether they contact specific

Histochemical Localization of the Cholinergic and Nitrergic Neurons in the Chicken Ileum [PDF]
Pakistan Veterinary Journal, 2012 Histochemical localization and analysis of the cholinergic and nitrergic neurons in the chicken ileum were investigated by staining with acetylcholine esterases (AChE) and nicotinamide adenine dinucleotide phosphate diaphorase (NADPH-d), respectively ...
