“Focal cerebral ischemia and traumatic brain injury induce an escalating amount of cell death because of harmful mediators diffusing from the original lesion site.
Evidence suggests that healthy cells surrounding these lesions attempt to protect themselves by producing endocannabinoids (eCBs) and activating cannabinoid receptors, the molecular target for marijuana-derived compounds.
Indeed, activation of cannabinoid receptors reduces the production and diffusion of harmful mediators.
Here, we provide evidence that an exception to this pattern is found in experimental autoimmuneencephalomyelitis (EAE), a mouse model of multiple sclerosis…
Our data suggest that the high level of CNS IFN-gamma associated with EAE disrupts eCB-mediated neuroprotection while maintaining functional cannabinoid receptors, thus providing additional support for the use of cannabinoid-based medicine to treat multiple sclerosis.”
