Anandamide and 2-AG Enzyme Inhibition Did Not Produce One Shared Memory Profile in Mice
A 2011 mouse experiment separated effects of enhancing anandamide signaling from effects of enhancing 2-AG signaling. Similar anxiety-like or antinociceptive findings did not establish an identical memory profile.
The intervention was enzyme inhibition
Researchers used low doses of inhibitors directed at FAAH and monoacylglycerol lipase, rather than administering marijuana. They assessed memory consolidation, anxiety-like behavior and nociception after acute and repeated exposure. The compounds altered endogenous signaling through different experimental approaches.
The outcomes dissociated
The authors implicated anandamide more directly than 2-AG in the memory-consolidation finding. Both interventions produced anxiety-related effects through different cannabinoid receptors. This supports keeping the measured functions separate instead of calling the entire behavioral pattern improved or impaired.
Repeated treatment retained selected responses
The reported antinociceptive, anxiety-like and memory effects were maintained during the repeated-treatment protocol. That finding belongs to the doses and tests used; it does not establish that every level of enzyme inhibition avoids tolerance or adverse effects.
Interpreting the evidence
This experiment helps distinguish two endogenous ligands and several behavioral endpoints. It does not show that cannabis reproduces either inhibitor's profile or establish a human anxiety or memory treatment. Species, intervention and measured domain limit the inference.
