Influence of marihuana on cellular structures and biochemical activities

Cannabinoids are known to affect a number of cellular systems and functions, but the basis for their action is unclear. In this paper we review the current evidence describing cannabinoid effects on various levels of cellular structure and activity and we present our current studies on the influence of delta-9-tetrahydrocannabinol, cannabidiol and cannabinol on one cellular system, the cytoskeleton. The organization of two cytoskeletal structures, microtubules and microfilaments, were examined and the mRNA levels of tubulin and actin, the major protein components of microtubules and microfilaments, respectively, were analysed.
