The Microbiome and Gut Endocannabinoid System in the Regulation of Stress Responses and Metabolism

Abstract

The endocannabinoid system, with its receptors and ligands, is present in the gut epithelium and enteroendocrine cells, and is able to modulate brain functions, both indirectly through circulating gut-derived factors and directly through the vagus nerve, finally acting on the brain's mechanisms regarding metabolism and behavior. The gut endocannabinoid system also regulates gut motility, permeability, and inflammatory responses. Furthermore, microbiota composition has been shown to influence the activity of the endocannabinoid system. This review examines the interaction between microbiota, intestinal endocannabinoid system, metabolism, and stress responses. We hypothesize that the crosstalk between microbiota and intestinal endocannabinoid system has a prominent role in stress-induced changes in the gut-brain axis affecting metabolic and mental health. Inter-individual differences are commonly observed in stress responses, but mechanisms underlying resilience and vulnerability to stress are far from understood. Both gut microbiota and the endocannabinoid system have been implicated in stress resilience. We also discuss interventions targeting the microbiota and the endocannabinoid system to mitigate metabolic and stress-related disorders.

Figures

FIGURE 1 The endocannabinoid system in the gastrointestinal tract. The crosstalk between the intestinal eCB system and microbiota regulates many GI functions, such as gut permeability, motility, hormonal secretion, nutrient absorption and immune response. CB1R is expressed in different cells in the gut, including epithelial cells (colored in violet) and different types of enteroendocrine cells (colored in yellow, L cell; blue, K cell, and green, I cell, respectively) in the mucosa layer. In the myenteric and submucosa plexus, CB1R is present in the enteric nervous system, in particular, in the cell bodies of cholinergic neurons containing the neurotransmitter acetylcholine (ACh). Furthermore, CB1R is expressed in the afferent vagal neurons. CB2R is expressed in immune cells as well as in the epithelial cells in the mucosa. AA, arachidonic acid; CCK, cholecystokinin; FA, fatty acids; GIP, gastric inhibitory peptide; GLP-1, glucose-like peptide 1; GPR119, G protein-coupled receptor 119; GPR120, G protein-coupled receptor 120; GPR40, G protein-coupled receptor 40; PYY, peptide YY.

FIGURE 2 Microbiota-gut-brain axis in the regulation of stress responses and metabolism. Mechanisms underlying the bidirectional communication include the vagus nerve, immune system, circulating mediators and HPA axis. Microbiota composition is affected by stress, diet, prebiotics, postbiotics and antibiotics among other factors. CCK, cholecystokinin; GLP-1, glucagon-like peptide-1; LPS, lipopolysaccharide; NPY, neuropeptide Y; PYY, polypeptide YY; SCFA, short chain fatty acid.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
