Cannabidiol (CBD), a natural product of the Cannabis sativa plant, is a TRPV2 agonist (Qin et al., 2008) which has been recently used to demonstrate the important role of TRPV2 in the inhibition of glioblastoma multiforme cell proliferation (Perálvarez-Marín et al., 2013; Liberati et al., 2014; Nabissi et al., 2010; Nabissi et al., 2015; Nabissi et al., 2013). This evidence concerns the gene TRPV2 and glioblastoma.
