The endocannabinoid system as a potential therapeutic target for pain modulation.

“Although cannabis has been used for pain management for millennia, very few approved cannabinoids are indicated for the treatment of pain and other medical symptoms.

Cannabinoid therapy re-gained attention only after the discovery of endocannabinoids and fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL), the enzymes playing a role in endocannabinoid metabolism.

Nowadays, research has focused on the inhibition of these degradative enzymes and the elevation of endocannabinoid tonus locally; special emphasis is given on multi-target analgesia compounds, where one of the targets is the endocannabinoid degrading enzyme.

In this review, I provide an overview of the current understanding about the processes accounting for the biosynthesis, transport and metabolism of endocannabinoids, and pharmacological approaches and potential therapeutic applications in this area, regarding the use of drugs elevating endocannabinoid levels in pain conditions.”

Oxidative stress and cannabinoid receptor expression in type-2 diabetic rat pancreas following treatment with Δ9 -THC.

“We can suggest that Δ9 -THC may be an important agent for the treatment of oxidative damages induced by diabetes…

Furthermore, the present study for the first time emphasizes that Δ9 -THC may improve pancreatic cells via cannabinoid receptors in diabetes.

The aim of present study was to elucidate the effects of Δ9 -THC, a natural cannabinoid receptor agonist, on the expression and localization of cannabinoid receptors, and oxidative stress statue in type-2 diabetic rat pancreas.

Results demonstrate that the cannabinoid receptors are presented in both Langerhans islets and duct regions.

The curative effects of Δ9 -THC can be occurred via activation of cannabinoid receptors in diabetic rat pancreas.

Moreover, it may provide a protective effect against oxidative damage induced by diabetes.

Thus, it is suggested that Δ9 -THC can be a candidate for therapeutic alternatives of diabetes symptoms.”

Cannabinoid Receptor Type 1 Antagonist, AM251, Attenuates Mechanical Allodynia and Thermal Hyperalgesia after Burn Injury.

“Burn injury causes nociceptive behaviors, and inflammation-related pathologic pain can lead to glial cell activation. This study tested the hypothesis that burn injury activates glial cells, and cannabinoid receptor 1 (CB1R) antagonist, AM251, will decrease burn pain.

CONCLUSIONS::

AM251 inhibited nociceptive behaviors after burn even beyond 7-day period of administration. Although many studies have documented the utility of CB1R agonists, this study indicates that endogenous cannabinoids may have an unexpected pronociceptive effect during development of burn pain, explaining why CB1R antagonist, AM251, improves nociceptive behaviors.”

Cannabinoid CB2 receptor (CB2R) stimulation delays rubrospinal mitochondrial-dependent degeneration and improves functional recovery after spinal cord hemisection by ERK1/2 inactivation.

“Spinal cord injury (SCI) is a devastating condition… Modulation of the endocannabinoid system (ECS) counteracts neurodegeneration, and pharmacological modulation of type-2 cannabinoid receptor (CB2R) is a promising therapeutic target for several CNS pathologies, including SCI…

These findings implicate the ECS, particularly CB2R, as part of the endogenous neuroprotective response that is triggered after SCI.

Thus, CB2R modulation might represent a promising therapeutic target that lacks psychotropic effects and can be used to exploit ECS-based approaches to counteract neuronal degeneration.”

Cannabinoid mouth spray brought help to a severely spastic young man.

“Cannabinoid was licensed in 2012 for the treatment of spasticity associated with multiple sclerosis in Finland. Spasticity is one of the main symptoms in cerebral palsies and a risk factor of multiple painful anomalies of the skeletal network. We describe a 28-year-old man with severe cerebral palsy, whose quality of life improved and the need for help decreased by using two daily mouth sprays of cannabinoid.”

Cannabinoids for Neuropathic Pain.

“Treatment options for neuropathic pain have limited efficacy and use is fraught with dose-limiting adverse effects.

The endocannabinoid system has been elucidated over the last several years, demonstrating a significant interface with pain homeostasis.

Exogenous cannabinoids have been demonstrated to be effective in a range of experimental neuropathic pain models, and there is mounting evidence for therapeutic use in human neuropathic pain conditions.

This article reviews the history, pharmacologic development, clinical trials results, and the future potential of nonsmoked, orally bioavailable, nonpsychoactive cannabinoids in the management of neuropathic pain.”

Neuropathic orofacial pain: cannabinoids as a therapeutic avenue.

“Neuropathic orofacial pain (NOP) exists in several forms including pathologies such as burning mouth syndrome (BMS), persistent idiopathic facial pain (PIFP), trigeminal neuralgia (TN) and postherpetic neuralgia (PHN).

The pathophysiology of some of these conditions is still unclear and hence treatment options tend to vary and include a wide variety of treatments including cognitive behavior therapy, anti-depressants, anti-convulsants and opioids; however such treatments often have limited efficacy with a great amount of inter-patient variability and poorly tolerated side effects.

Analgesia is one the principal therapeutic targets of the cannabinoid system and many studies have demonstrated the efficacy of cannabinoid compounds in the treatment of neuropathic pain.

This review will investigate the potential use of cannabinoids in the treatment of symptoms associated with NOP.”

The Role of Endocannabinoid Signaling in the Molecular Mechanisms of Neurodegeneration in Alzheimer’s Disease.

“Alzheimer’s disease (AD) is the most common form of progressive neurodegenerative disease characterized by cognitive impairment and mental disorders… AD is multifaceted in nature and is linked to different multiple mechanisms in the brain…

The ideal treatment for AD should be able to modulate the disease through multiple mechanisms rather than targeting a single dysregulated pathway.

Recently, the endocannabinoid system emerged as novel potential therapeutic target to treat AD.

In fact, exogenous and endogenous cannabinoids seem to be able to modulate multiple processes in AD, although the mechanisms that are involved are not fully elucidated.

This review provides an update of this area. In this review, we recapitulate the role of endocannabinoid signaling in AD and the probable mechanisms through which modulators of the endocannabinoid system provide their effects, thus highlighting how this target might provide more advantages over other therapeutic targets.”

Cannabinoids: a novel treatment for glaucoma

Acta Ophthalmologica

“…cannabinoids are emerging novel agents for the treatment of glaucoma.

Although increased intraocular pressure (IOP) is a risk factor, associated retinal damage is of prime concern. This study determines the ability of cannabinoids to decrease IOP and confer neuroprotection…

Conclusion: Topically applied cannabinoids are effective agents that reduce IOP and confer neuroprotection and are prime candidates for potential glaucoma treatment.”

“Cannabinoid agonists might serve as neuroprotective agents in neurodegenerative disorders… Cannabinoids may also offer neuroprotection in Huntington’s disease (HD)…

Here, we examined this hypothesis in a rat model ofHuntington’s disease (HD)…

Our results showed that only compounds able to activate CB2 receptors were capable of protecting striatal projection neurons from malonate-induced death. That CB2 receptor agonists are neuroprotective was confirmed…

…neuroprotection was attained exclusively with antioxidant cannabinoids like Δ9-tetrahydrocannabinol (Δ9-THC; or cannabidiol (CBD)…

In summary, our results demonstrate that stimulation of CB2 receptors protect the striatum against malonate toxicity, likely through a mechanism involving glial cells, in particular reactive microglial cells in which CB2 receptors would be upregulated in response to the lesion. Activation of these receptors would reduce the generation of proinflammatory molecules like TNF-alpha.

Altogether, our results support the hypothesis that CB2 receptors could constitute a therapeutic target to slowdown neurodegeneration in HD.”
