Abstract Anandamide and other fatty acid amides are metabolised by the enzyme fatty acid amide hydrolase (FAAH), which thereby regulates their endogenous levels. Here we demonstrate that cultured rat cortical microglia express FAAH at low levels. The potent FAAH inhibitor URB597 reduced the LPS stimulated microglial expression of cyclo-oxygenase 2 and inducible nitric oxide, with concomitant attenuation of the release of PGE2 and NO. Additional of supplemental exogenous anandamide did not increase the magnitude of attenuation of mediator release. The effect of URB597 on LPS stimulated PGE2 release was not blocked by selective CB1 or CB2 receptor antagonists.
