β1/2 or M2/3 Receptors Are Required for Different Gastrointestinal Motility Responses Induced by Acupuncture at Heterotopic or Homotopic Acupoints. [PDF]

PLoS ONE, 2016
Acupuncture at homotopic acupoints or heterotopic acupoints is known to either inhibit or facilitate gastrointestinal motility, depending on the acupoint location.

Structure of the human M2 muscarinic acetylcholine receptor bound to an antagonist [PDF]

Nature, 2012
The parasympathetic branch of the autonomic nervous system regulates the activity of multiple organ systems. Muscarinic receptors are G-protein-coupled receptors that mediate the response to acetylcholine released from parasympathetic nerves. Their role in the unconscious regulation of organ and central nervous system function makes them potential ...

Review of nutrition management of pediatric intestinal pseudo‐obstruction

Nutrition in Clinical Practice, EarlyView.
Abstract Chronic intestinal pseudo‐obstruction (CIPO) is a rare, heterogeneous, and debilitating disorder characterized by profound intestinal dysmotility and severe nutrition challenges. Its presentation resembles that of mechanical bowel obstruction, but CIPO occurs in the absence of luminal obstruction.

Drug Repurposing on G Protein-Coupled Receptors Using a Computational Profiling Approach

Frontiers in Molecular Biosciences, 2021
G protein-coupled receptors (GPCRs) are the largest human membrane receptor family regulating a wide range of cell signaling. For this reason, GPCRs are highly desirable drug targets, with approximately 40% of prescribed medicines targeting a member of ...

Acetylcholine From Solitary Chemosensory Cell, Not Neuron, Regulates Basal Cell Fate Driving Eosinophilic Chronic Rhinosinusitis With Nasal Polyps

Allergy, EarlyView.
This study identifies that Ach levels are elevated in eCRSwNP and primarily released from SCCs rather than neurons. Ach induces epithelial remodeling in eCRSwNP by binding to M1R/M3R and activating YAP signaling in basal cells, driving basal cell hyperplasia and abnormal differentiation. Blocking M1R/M3R with TB inhibits eCRSwNP progression.

Oral Vitamin C Intake Ameliorates Crude Oil-Polluted Water-Induced Jejunal Contractile Dysfunctions in Wistar rats

Journal of Applied Sciences and Environmental Management, 2023
Inhabitants of rural Niger-Delta oil communities in Nigeria often, unintentionally, consume crude oil polluted water (COCW) due to crude oil spills in the region. The impact of vitamin C supplementation during COCW ingestion on the contractile mechanism
