The role of carbon monoxide on the anti-nociceptive effects and expression of cannabinoid 2 receptors during painful diabetic neuropathy in mice.

Posted on March 30, 2016 by David

“The activation of cannabinoid 2 receptors (CB2R) attenuates chronic pain, but the role played by carbon monoxide synthesized by the inducible heme oxygenase 1 (HO-1) on the anti-nociceptive effects produced by a selective CB2R agonist, JWH-015, during painful diabetic neuropathy remains unknown.

The activation of HO-1 enhanced the anti-nociceptive effects of JWH-015 in diabetic mice, suggesting that coadministration of JWH-015 with CORM-2 or CoPP might be an interesting approach for the treatment of painful diabetic neuropathy in mice.”

Tonic Modulation of Nociceptive Behavior and Allodynia by Cannabinoid Receptors in Formalin Test in Rats.

Posted on February 18, 2015 by David

“Cannabinoids produce anti-nociceptive and anti-hyperalgesic effects in acute, inflammatory and neuropathic pain models.

The current study investigated the role of cannabinoid (CB1 and CB2) receptors in modulating formalin-induced nociceptive behavior and mechanical allodynia in the rat…

The results indicate that CB1 and CB2 receptors mediate a tonically inhibitory action on formalin-induced inflammatory pain, especially long-term allodynia, in bilateral hind paws.”

Cannabinoids and muscular pain. Effectiveness of the local administration in rat.

Posted on December 3, 2014 by David

“Pain associated with musculoskeletal disorders can be difficult to control and the incorporation of new approaches for its treatment is an interesting challenge.

Activation of cannabinoid (CB) receptors decreases nociceptive transmission in acute, inflammatory and neuropathic pain states…

Our results provide evidence that both, CB 1 and CB 2 receptors can contribute to muscular antinociception and, interestingly, suggest that the local administration of CB agonists could be a new and useful pharmacological strategy in the treatment of muscular pain, avoiding adverse effects induced by systemic administration.”

Involvement of the endocannabinoid system in osteoarthritis pain.

Posted on February 6, 2014 by David

“Increasing evidence from preclinical studies supports the interest of the endocannabinoid system as an emerging therapeutic target for osteoarthritis pain.

Indeed, pharmacological studies have shown the anti-nociceptive effects of cannabinoids in different rodent models of osteoarthritis, and compelling evidence suggests an active participation of the endocannabinoid system in the pathophysiology of this disease.

The ubiquitous distribution of cannabinoid receptors, together with the physiological role of the endocannabinoid system in the regulation of pain, inflammation and even joint function further support the therapeutic interest of cannabinoids for osteoarthritis.

…review summarizes the promising results that have been recently obtained in support of the therapeutic value of cannabinoids for osteoarthritis management.”

Cannabinoids Attenuate Cancer Pain and Proliferation in a Mouse Model

Posted on May 30, 2013 by David

“Oral cancer represents 3% of all cancers and its overall survival rate of 50% places it among the worst of all cancers

For many years cannabinoids have been used for medicinal and recreational purposes.

Recently, studies have focused on the therapeutic effects of cannabinoids on different cancers. The current study was the first to investigate the therapeutic effects of synthetic cannabinoids on oral cancer.

We investigated the effects of cannabinoid receptor agonists on (1) oral cancer cell viability in vitro and (2) oral cancer pain and tumor growth in a mouse cancer model.

Here we demonstrate the anti-nociceptive and anti-proliferative effects of systemic administration of cannabinoid receptor agonists on human oral cancer cells.

Our results suggest that systemic administration of cannabinoids decease oral cancer pain.

Our findings suggest a direct role for cannabinoid mechanisms in oral cancer pain and proliferation.

The systemic administration of cannabinoid receptor agonists may have important therapeutic implications wherein cannabinoid receptor agonists may reduce morbidity and mortality of oral cancer.

The present findings suggest that cannabinoid treatment may be a promising alternative therapy for oral cancer pain management. Furthermore, CBr2 agonism is not only palliative, but it may also be effective in inhibiting oral cancer growth, making the agonist a particularly desirable therapeutic agent.”
