The present invention relates to a method for modulating blood-brain barrier (BBB) in a subject comprising a step of administering said subject with a therapeutically effective amount of a modulator of transient receptor potential vanilloid-2 (TRPV2). For the first time, inventors have shown that TRPV2 is present in endothelial cells of BBB. More particularly, Inventor’s results show that cannabidiol (CBD), at extracellular concentrations close to those observed in plasma of patients treated by CBD, and induces proliferation, migration, tubulogenesis and TEER increase in human brain endothelial cells, suggesting TRPV2 as a potent target for modulating the human BBB.
