The Endocannabinoid System in Pediatric Inflammatory and Immune Diseases.

ABSTRACT: Endocannabinoid system consists of cannabinoid type 1 (CB1) and cannabinoid type 2 (CB2) receptors, their endogenous ligands, and the enzymes responsible for their synthesis and degradation. CB2, to a great extent, and CB1, to a lesser extent, are involved in regulating the immune response. They also regulate the inflammatory processes by inhibiting pro-inflammatory mediator release and immune cell proliferation. This review provides an overview on the role of the endocannabinoid system with a major focus on cannabinoid receptors in the pathogenesis and onset of inflammatory and autoimmune pediatric diseases, such as immune thrombocytopenia, juvenile idiopathic arthritis, inflammatory bowel disease, celiac disease, obesity, neuroinflammatory diseases, and type 1 diabetes mellitus. These disorders have a high social impact and represent a burden for the healthcare system, hence the importance of individuating more innovative and effective treatments. The endocannabinoid system could address this need, representing a possible new diagnostic marker and therapeutic target.

Project description:Background:Mononuclear phagocytes, such as monocytes, macrophages, and dendritic cells, are important cellular components of the innate immune system that contribute to the pathogenesis of many intestinal inflammatory diseases. Summary:While mononuclear phagocytes play a key role in the induction of inflammation in many different tissues through production of pro-inflammatory cytokines and chemokines (such as IL-1, TNF, IL-6, IL-8 and MCP-1), free oxygen radicals (also termed 'oxidative burst'), proteases (such as cathepsins) and tissue-degrading enzymes (such as metalloproteinases), resident macrophages as well as dendritic cells in the intestine display an anergic and 'tolerogenic' phenotype mediating tolerance to commensal bacteria. In recent years many single nucleotide polymorphisms (SNPs) in genes mainly expressed in the above-mentioned cell types have been identified to convey an increased risk of autoimmune diseases. SNPs in the NOD2, ATG16L1 and TNFSF15 genes, which are involved in the function of the innate immune cells, are identified as risk factors for Crohn's disease (CD). Of note, these genes are involved in the different functions in the innate immune cells. For example, while NOD2 is required for intracellular recognition of microbial components, ATG16L1 is involved in autophagy responses against intracellular microbes. Likewise, TNFSF15 contributes to the induction of inflammatory responses by innate immune cells. Furthermore, the frequency of mutations in these genes differs by ethnicity. Genetic variations in the NOD2 and ATG16L1 genes are associated with CD in Caucasians but much less in Eastern Asian populations, whereas SNPs in TNFSF15 are dominated in Asian populations. Thus, different genetic risks may eventually lead to similar impairments in innate immune cells, thereby developing the same disease in Western and Asian patients with CD. Key Messages:Despite differences in risk genes, similar mechanisms associated with the innate immune system may trigger autoimmune and chronic inflammatory intestinal diseases in East and West.
