Therapeutic Potential of Phytocannabinoid Cannabigerol for Multiple Sclerosis: Modulation of Microglial Activation In Vitro and In Vivo

Multiple sclerosis (MS) is a widespread chronic neuroinflammatory and neurodegenerative disease. Microglia play a crucial role in the pathogenesis of MS via the release of cytokines and reactive oxygen species, e.g., nitric oxide. Research involving the role of phytocannabinoids in neuroinflammation is currently receiving much attention. Cannabigerol is a main phytocannabinoid, which has attracted significant pharmacological interest due to its non-psychotropic nature. In this research, we studied the effects of cannabigerol on microglial inflammation in vitro, followed by an in vivo study. Cannabigerol attenuated the microglial production of nitric oxide in BV2 microglia and primary glial cells; concomitant treatment of the cells with cannabigerol and telmisartan (a neuroprotective angiotensin receptor blocker) decreased nitric oxide production additively. Inducible nitric oxide synthase (iNOS) expression was also reduced by cannabigerol.
