Cannabidiol protects an in vitro model of the blood brain barrier (BBB) from oxygen-glucose deprivation via PPARγ and 5-HT1A.

“In vivo and in vitro studies have demonstrated a protective effect of cannabidiol (CBD) in reducing infarct size in stroke models, and against epithelial barrier damage in numerous disease models.

We aimed to investigate whether CBD also affects blood-brain barrier (BBB) permeability following ischaemia.

These data suggest that activity at the BBB could represent an as yet unrecognised mechanism of CBD-induced neuroprotection in ischaemic stroke, mediated by PPARγ and 5-HT1A .”
