Selective Activation of Cannabinoid Receptor 2 in Leukocytes Suppresses Their Engagement of the Brain Endothelium and Protects the Blood-Brain Barrier.

“Cannabinoid receptor 2 (CB2) is highly expressed in immune cells and stimulation decreases inflammatory responses. We tested the idea that selective CB2 activation in human monocytes suppresses their ability to engage the brain endothelium and migrate across the blood-brain barrier (BBB), preventing consequent injury…

These results indicate that selective CB2 activation in leukocytes decreases key steps in monocyte-BBB engagement, thus suppressing inflammatory leukocyte responses and preventing neuroinflammation.”
