In mouse brains & in cell cultures, CB2 receptors shown to form heteromer complexes with NMDA receptors (which control glutamate)

N-Methyl-D-aspartate (NMDA) and cannabinoid CB2 receptors form functional complexes in cells of the central nervous system: insights into the therapeutic potential of neuronal and microglial NMDA receptors

Heteromer complexes are a crazy thing. It turns out that if you take two wildly different receptors like the CB2 receptor & the NMDA receptor, they naturally link up in the cellular membranes of the neurons. When they form these complexes, the complexes have different downstream effects than either receptor acting alone. In this case, it seems to help explain the strong neuroprotection properties of the cannabinoids via their ability to work with glutamate, the brain's primary excitatory neurotransmitter.
