Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

596
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,...

Inflammatory Response01:28

Inflammatory Response

15.6K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Immune Response Against Viral Pathogens

1.6K
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Allergic Drug Reactions01:27

Allergic Drug Reactions

1.3K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

T Cell Types and Functions01:24

T Cell Types and Functions

2.0K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

6.3K
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

Area of Science:

  • Immunology
  • Pharmacology
  • Neuroscience

Background:

  • Cannabidiol (CBD) is increasingly used for medical purposes, with FDA approval for epilepsy treatment.
  • Understanding CBD's biological effects, particularly on the immune system, is crucial due to rising exposure.
  • CBD's anti-inflammatory and immune-suppressive properties warrant detailed investigation.

Purpose of the Study:

  • To review the effects and mechanisms of CBD on the immune system.
  • To identify potential receptors mediating CBD's immune effects.
  • To summarize in vivo and in vitro findings, including autoimmune models like experimental autoimmune encephalomyelitis.

Main Methods:

  • Literature review of existing studies on CBD and the immune system.
  • Analysis of in vivo and in vitro experimental data.
  • Focus on autoimmune disease models, specifically experimental autoimmune encephalomyelitis.

Main Results:

  • CBD exhibits immune-suppressive properties.
  • Mechanisms include direct suppression of immune cell activation.
  • CBD induces apoptosis and promotes regulatory immune cells.

Conclusions:

  • The data strongly support CBD as an immune-suppressive agent.
  • CBD modulates immune responses through multiple mechanisms.
  • Further research is needed to identify knowledge gaps regarding CBD's immune effects.
