“Long term exposure to stress has been demonstrated to cause neuroinflammation through a sustained overproduction of free radicals, including nitric oxide, via an increased inducible nitric oxide synthase (iNOS) activity.

Similar to nitric oxide, endocannabinoids are synthesised on demand, with preclinical observations suggesting that cannabinoid receptor agonists and endocannabinoid enhancers inhibit nitrergic activity.

RESULTS:

The results demonstrate that pre-treatment with PF-3845 rapidly ameliorates plasma corticosterone release at 60 minutes of stress. An increase in endocannabinoid signalling also induces an overall attenuation in iNOS, tumor necrosis factor-alpha convertase, interleukin-6, cyclooxygenase-2, peroxisome proliferator-activated receptor gamma mRNA, and the transactivation potential of NF-κB in the hippocampus.

CONCLUSIONS:

These results suggest that enhanced endocannabinoid levels in the dorsal hippocampus have an overall anti-nitrosative and anti-inflammatory effect following acute stress exposure.”
