Abstract

Cannabinoids have recently been approved as a treatment for pain in multiple sclerosis (MS). Increasing evidence from animal studies suggests that this class of compounds could also prove efficient to fight neurodegeneration, demyelination, inflammation and autoimmune processes occurring in this pathology. However, the use of cannabinoids is limited by their psychoactive effects. In this context, potentiation of the endogenous cannabinoid signalling could represent a substitute to the use of exogenously administrated cannabinoid ligands. Here, we studied the expression of different elements of the endocannabinoid system in a chronic model of MS in mice. We first studied the expression of the two cannabinoid receptors, CB(1) and CB(2), as well as the putative intracellular cannabinoid receptor peroxisome proliferator-activated receptor-alpha. We observed an upregulation of CB(2), correlated to the production of proinflammatory cytokines, at 60 days after the onset of the MS model. At this time, the levels of the endocannabinoid, 2-arachidonoylglycerol, and of the anti-inflammatory anandamide congener, palmithoylethanolamide, were enhanced, without changes in the levels of anandamide. These changes were not due to differences in the expression of the degradation enzymes, fatty acid amide hydrolase and monoacylglycerol lipase, or of biosynthetic enzymes, diacylglycerol lipase-alpha and N-acylphosphatidylethanolamine phospholipase-D at this time (60 days). Finally, the exogenous administration of palmitoylethanolamide resulted in a reduction of motor disability in the animals subjected to this model of MS, accompanied by an anti-inflammatory effect. This study overall highlights the potential therapeutic effects of endocannabinoids in MS.

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.
