Mucosal acid challenge activates nitrergic neurons in myenteric plexus of rat stomach

open access: yes, 2001
We tested the hypothesis that intrinsic neurons of the rat gastric myenteric plexus can be activated by an acid (HCl) challenge of the mucosa. Activated neurons were visualized by immunohistochemical detection of c-Fos, a marker for neuronal excitation.

Collagen and microvascular alterations contribute to neuromuscular degeneration and disease progression in chronic intestinal pseudo‐obstruction

open access: yesJournal of Internal Medicine, Volume 299, Issue 5, Page 587-603, May 2026.
Abstract Background Chronic intestinal pseudo‐obstruction (CIPO) is a severe gastrointestinal motility disorder that may be idiopathic or associated with systemic disease. In idiopathic cases, the pathophysiological mechanisms remain poorly defined. Although mutations in angiogenic factors have been reported in mitochondrial forms of CIPO, their role ...

Immediate-Early Gene Expression in the Inferior Mesenteric Ganglion and Colonic Myenteric Plexus of the Guinea Pig

open access: yes, 1999
Activation of neurons in the inferior mesenteric ganglion (IMG) was assessed using c-fos, JunB, and c-Jun expression in the guinea pig IMG and colonic myenteric plexus during mechanosensory stimulation and acute colitis in normal and capsaicin-treated ...

Optical Mapping of Pacing‐Elicited Slow Waves in the Swine Stomach: Role of Virtual Electrodes

open access: yesNeurogastroenterology &Motility, Volume 38, Issue 5, May 2026.
Unipolar electrical pacing stimuli delivered to the stomach wall induce adjacent regions of both depolarized and hyperpolarized tissue known as virtual electrodes. Electrical slow waves elicited by pacing start from depolarized virtual electrodes approximately 1 cm from the pacing electrode site and not from the electrode site itself.

The effect of ascorbate on the acetylcholine release from guinea-pig ileal myenteric plexus

open access: yes, 1986
The effect of ascorbate on the release of acetylcholine from the longitudinal muscle-myenteric plexus preparation of the guinea-pig isolated ileum has been investigated using a bioassay and an isotopic technique.

Morphologic and quantitative study of the myenteric neurons of the jejunum of malnourished rats (Rattus norvegicus) [PDF]

open access: yesArquivos de Neuro-Psiquiatria, 1999
We studied the effects of maternal proteic desnutrition on the neurons of the myenteric plexus of the jejunum of rats from Rattus norvegicus species. It was used litters of female rats which received diet with normal proteic level during gestation and ...

Herpes Simplex Virus Type 1 Infects Enteric Neurons and Triggers Gut Dysfunction via Macrophage Recruitment

open access: yesFrontiers in Cellular and Infection Microbiology, 2018
Herpes Simplex Virus type 1 (HSV-1), a neurotropic pathogen widespread in human population, infects the enteric nervous system (ENS) in humans and rodents and causes intestinal neuromuscular dysfunction in rats.

Intestinal anaphylaxis induces Fos immunoreactivity in myenteric plexus of rat small intestine

open access: yes, 1997
Fos immunohistochemistry was used to identify myenteric neurons activated as a consequence of intestinal anaphylaxis in Hooded-Lister rats sensitized to egg albumin (EA 10 micrograms ip).
