It is reported for the first time that both CB1 and CB2 receptors modulate release of endogenous IL-1ra from primary cultured glial cells, and this data suggest a novel neuroprotective mechanism of action for CBs in response to inflammatory or excitotoxic insults.

Potencies of compounds active at N-Me-D-Asp and PCP receptors in oocytes were comparable to those obtained previously in electrophysiological and binding assays on neural tissues, and stereoselective in that the active ligand dexoxadrol was a more effective blocker than its relatively inactive stereoisomer levoxadro.

The most parsimonious explanation of the data is that NMDA receptor ligands regulate TCP binding by controlling access of TCP to a transiently accessible or "guarded" binding site located in the receptor-coupled ion channel.
