Arachidonylcyclopropylamide increases microglial cell migration through cannabinoid CB2 and abnormal-cannabidiol-sensitive receptors.

“Microglial cells, the macrophages of the brain, express low, yet detectable levels of cannabinoid CB(1) receptors, which are known to modulate cell migration.

To determine if cannabinoid CB(1) receptors expressed by microglial cells modulate their migration, we assessed whether arachidonylcyclopropylamide (ACPA, an agonist shown to selectively activate CB(1) receptors) affects the migration of BV-2 cells, a mouse microglial cell line.

Our results suggest that cannabinoid CB(2) receptors and abn-CBD receptors, rather than cannabinoid CB(1) receptors, regulate microglial cell migration, and that ACPA is a broad cannabinoid receptor agonist.”
