Cannabinoids Δ9-Tetrahydrocannabinol and Cannabidiol Differentially Inhibit the Lipopolysaccharide-activated NF-κB and Interferon-β/STAT Proinflammatory Pathways in BV-2 Microglial Cells

“Cannabinoids have been shown to exert anti-inflammatory activities in various in vivo and in vitro experimental models as well as ameliorate various inflammatory degenerative diseases. Δ9-Tetrahydrocannabinol (THC)is a major constituent of Cannabis and serves as an agonist of the cannabinoid receptors CB1 and CB2.

The second major constituent of Cannabis extract is cannabidiol (CBD). CBD lacks the psychoactive effects that accompany the use of THC. Moreover, CBD was demonstrated to antagonize some undesirable effects of THC, including intoxication, sedation, and tachycardia, while sharing neuroprotective, anti-oxidative, anti-emetic, and anti-carcinogenic properties. Both THC and CBD have been shown to exert anti-inflammatory properties and to modulate the function of immune cells…

In summary, our results show that although both THC and CBD exert anti-inflammatory effects, the two compounds engage different, although to some extent overlapping, intracellular pathways. Both THC and CBD decrease the activation of proinflammatory signaling…

 The cannabinoids by moderating or disrupting these signaling networks may show promise as anti-inflammatory agents.”
