Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

Opioid Receptors: Overview

Opioid Receptors: Overview

Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2, D-Pen5]-enkephalin or DPDPE for...

Gut-Brain Axis

Gut-Brain Axis

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...

Analgesia and Pain Management

Analgesia and Pain Management

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

An Overview of the Endocrine System

An Overview of the Endocrine System

The endocrine system, a complex network of glands, orchestrates physiological balance within the body through the production and secretion of hormones. These hormones are chemical messengers in intercellular communication, acting as conduits between the secretory cells and distant target sites. They traverse the circulatory system by being released into the extracellular fluid, and their impact is specific to cells possessing receptors for a particular hormone.
The endocrine system collaborates...

What is the Endocrine System?

What is the Endocrine System?

The endocrine system sends hormones—chemical signals—through the bloodstream to target cells—the cells the hormones selectively affect. These signals are produced in endocrine cells, secreted into the extracellular fluid, and then diffuse into the blood. Eventually, they diffuse out of the blood and bind to target cells which have specialized receptors to recognize the hormones.

Area of Science:

Gastroenterology
Neurogastroenterology
Endocrinology

Background:

Cannabis has long been known to affect intestinal motility and secretion.
The discovery of cannabinoid receptors and endocannabinoids has spurred research into the endocannabinoid system's role in gut function.
This system is increasingly recognized for its involvement in gastrointestinal (GI) health and disease.

Purpose of the Study:

To review recent developments in endocannabinoid research related to the GI tract.
To emphasize novel findings on endocannabinoid control of intestinal motility and receptor functions.
To explore the therapeutic potential of targeting the endocannabinoid system for GI disorders.

Main Methods:

Review of recent scientific literature, with emphasis on data published in Neurogastroenterology & Motility.
Analysis of studies investigating endocannabinoid control of intestinal motility.
Examination of the roles of cannabinoid type-1 (CB1) and cannabinoid type-2 (CB2) receptors in the gut.
Discussion of the pharmacology of endocannabinoid-related molecules and plant cannabinoids.

Main Results:

Evidence suggests potential tonic endocannabinoid control of intestinal motility.
Cannabinoid type-1 (CB1) receptors play a role in gastric function, visceral pain, inflammation, and sepsis.
Cannabinoid type-2 (CB2) receptors are emerging as significant players in gut function.
Novel data highlight the diverse functions of endocannabinoids in the GI tract.

Conclusions:

The endocannabinoid system has multi-faceted roles in the gastrointestinal tract.
Targeting the endocannabinoid system shows promise for future therapeutic strategies in treating GI disorders.
Further research is warranted to fully elucidate the role of endocannabinoids in gut physiology and pathology.
