Inhibition of FAAH reduces nitroglycerin-induced migraine-like pain and trigeminal neuronal hyperactivity in mice

Nozaki, Chihiro, Markert, Astrid, Zimmer, Andreas·2015·European Neuropsychopharmacology

Abstract

There is evidence to suggest that a dysregulation of endocannabinoid signaling may contribute to the etiology and pathophysiology of migraine. Thus, patients suffering from chronic migraine or medication overuse headache showed alterations in the activity of the arachidonoylethanolamide (AEA) degrading enzyme fatty acid amide hydrolase (FAAH) and a specific AEA membrane transporter, alongside with changes in AEA levels. The precise role of different endocannabinoid system components is, however, not clear. We have therefore investigated mice with a genetic deletion of the two main cannabinoid receptors CB1 and CB2, or the main endocannabinoid degrading enzymes, FAAH and monoacylglycerol lipase (MAGL), which degrades 2-arachidonoylglycerol (2-AG), in a nitroglycerine-induced animal model of migraine. We found that nitroglycerin-induced mechanical allodynia and neuronal activation of the trigeminal nucleus were completely abolished in FAAH-deficient mice. To validate these results, we used two structurally different FAAH inhibitors, URB597 and PF3945. Both inhibitors also dose-dependently blocked nitroglycerin-induced hyperalgesia and the activation of trigeminal neurons. The effects of the genetic deletion of pharmacological blockade of FAAH are mediated by CB1 receptors, because they were completely disrupted with the CB1 antagonist rimonabant. These results identify FAAH as a target for migraine pharmacotherapy.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • FAAH inhibitors (PF-3845 and URB597) reverse allodynia in a mouse model of nitroglycerin-induced migraine through a CB1 receptor-dependent mechanism.

    “FAAH inhibitors (ie, PF-3845 and URB597) reverse allodynia in a mouse model of nitroglycerin-induced migraine through a CB 1 receptor-dependent mechanism (Nozaki et al, 2015).”
  • A dysfunction of the endocannabinoid system may contribute to the development of migraine attacks, and modulation of this system can be useful for the treatment of pain associated with migraine.

    “These studies suggest that a dysfunction of the endocannabinoid system may contribute to the development of migraine attacks and modulation of this system can be useful for the treatment of pain associated to migraine.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
