Low‐Concentration Dopamine Potentiates Gastric Motility Through Activation of Dopamine D5 Receptor on Enteric Cholinergic Neurons

Gut Medicine, EarlyView.
ABSTRACT Background Dopamine (DA) exerts complex concentration‐dependent effects on gastrointestinal motility. Although its inhibitory action through D2‐like receptors is well‐established, the mechanisms underlying its excitatory effects remain elusive.

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 ...

Bombesin-Stimulated Acetylcholine Release from Myenteric Plexus Neurons

, 1993
The ability of bombesin to stimulate acetylcholine release from guinea pig myenteric plexus neurons was studied using a primary neuronal culture system. Bombesin caused dose-dependent increases in [3H]acetylcholine (ACh) release from guinea pig myenteric

Glial Cells in the Myenteric Plexus

Zeitschrift für Naturforschung B, 1971
In the myenteric plexus of rat stomach, ileum, and rectum, glial cells outnumber nerve cells by more than 3 to 1; they have several processes, extensively branching, which extend between, and adapt themselves to, other cellular elements, constituting a very compact structure.

Exocrine Gland Dysfunction in Parkinson's Disease: Pathophysiology, Clinical Manifestations, and Therapeutic Perspectives—A Narrative Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Non‐motor symptoms, especially autonomic dysfunction, are major contributors to disability and decreased quality of life in Parkinson's disease (PD). Despite being common and having a wide range of clinical facets, exocrine gland dysfunction is still not well recognized and managed.

Somatostatin release from isolated ganglia of the myenteric plexus

, 1989
Somatostatin neurons of the myenteric plexus project caudad exclusively within the plexus synapsing with neurons in the same or other ganglia. Isolated ganglia offer a unique opportunity to examine peptide transmitter release from these interneurons ...

Age-related structural changes in the myenteric nervous plexus ganglion along the anterior wall of the proximal human duodenum: A morphometric analysis [PDF]

Vojnosanitetski Pregled, 2013
Background/Aim. Aging is one of the most complex biological processes which probably affect structure and function of the enteric nerve system. However, there is not much available information on this topic, particularly in humans.

Toll‐like receptor 4 mediates lipopolysaccharide‐induced emesis

British Journal of Pharmacology, EarlyView.
Background and Purpose Lipopolysaccharide (LPS) induces inflammation and sepsis through Toll‐like receptor 4 (TLR4) activation. Common laboratory animals do not exhibit emesis, but administration of LPS in piglets, cats, and dogs induces emesis via peripheral mechanisms.
