The postmortal accumulation of brain N-arachidonylethanolamine (anandamide) is dependent upon fatty acid amide hydrolase activity.
N-arachidonylethanolamine (AEA) accumulates during brain injury and postmortem. Because fatty acid amide hydrolase (FAAH) regulates brain AEA content, the purpose of this study was to determine its role in the postmortal accumulation of AEA using FAAH null mice. As expected, AEA content in immediately frozen brain tissue was significantly greater in FAAH-deficient (FAAH-/-) than in wild-type mi...
متن کاملAnandamide transport is independent of fatty-acid amide hydrolase activity and is blocked by the hydrolysis-resistant inhibitor AM1172.
The endogenous cannabinoid anandamide is removed from the synaptic space by a high-affinity transport system present in neurons and astrocytes, which is inhibited by N-(4-hydroxyphenyl)-arachidonamide (AM404). After internalization, anandamide is hydrolyzed by fatty-acid amide hydrolase (FAAH), an intracellular membrane-bound enzyme that also cleaves AM404. Based on kinetic evidence, it has rec...
متن کاملInvolvement of Fatty Acid Amide Hydrolase and Fatty Acid Binding Protein 5 in the Uptake of Anandamide by Cell Lines with Different Levels of Fatty Acid Amide Hydrolase Expression: A Pharmacological Study. PLoS ONE
Background: The endocannabinoid ligand anandamide (AEA) is removed from the extracellular space by a process of cellular uptake followed by metabolism. In many cells, such as the RBL-2H3 cell line, inhibition of FAAH activity reduces the observed uptake, indicating that the enzyme regulates uptake by controlling the intra: extracellular AEA concentration gradient. However, in other FAAH-express...

متن کاملA Personal Retrospective: Elevating Anandamide (AEA) by Targeting Fatty Acid Amide Hydrolase (FAAH) and the Fatty Acid Binding Proteins (FABPs)
This perspective was adapted from a Career Achievement Award talk given at the International Cannabinoid Research Society Symposium in Bukovina, Poland on June 27, 2016. As a biochemist working in the neurosciences, I was always fascinated with neurotransmitter inactivation. In 1993 we identified an enzyme activity that breaks down anandamide. We called the enzyme anandamide amidase, now called...
