Abstract

BACKGROUND AND PURPOSE Inflammatory pain presents a problem of clinical relevance and often elicits allodynia, a condition in which non‐noxious stimuli are perceived as painful. One potential target to treat inflammatory pain is the endogenous cannabinoid (endocannabinoid) system, which is comprised of CB 1 and CB 2 cannabinoid receptors and several endogenous ligands, including anandamide (AEA). Blockade of the catabolic enzyme fatty acid amide hydrolase (FAAH) elevates AEA levels and elicits antinociceptive effects, without the psychomimetic side effects associated with Δ 9‐tetrahydrocannabinol (THC). EXPERIMENTAL APPROACH Allodynia was induced by intraplantar injection of LPS. Complementary genetic and pharmacological approaches were used to determine the strategy of blocking FAAH to reverse LPS‐induced allodynia. Endocannabinoid levels were quantified using mass spectroscopy analyses. KEY RESULTS FAAH (−/−) mice or wild‐type mice treated with FAAH inhibitors (URB597, OL‐135 and PF‐3845) displayed an anti‐allodynic phenotype. Furthermore, i.p. PF‐3845 increased AEA levels in the brain and spinal cord. Additionally, intraplantar PF‐3845 produced a partial reduction in allodynia. However, the anti‐allodynic phenotype was absent in mice expressing FAAH exclusively in the nervous system under a neural specific enolase promoter, implicating the involvement of neuronal fatty acid amides (FAAs). The anti‐allodynic effects of FAAH‐compromised mice required activation of both CB 1 and CB 2 receptors, but other potential targets of FAA substrates (i.e. µ‐opioid, TRPV1 and PPARα receptors) had no apparent role. CONCLUSIONS AND IMPLICATIONS AEA is the primary FAAH substrate reducing LPS‐induced tactile allodynia. Blockade of neuronal FAAH reverses allodynia through the activation of both cannabinoid receptors and represents a promising target to treat inflammatory pain.

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.
