Protective effects of cannabidiol on lesion-induced intervertebral disc degeneration.

Posted on January 23, 2015 by David

“Disc degeneration is a multifactorial process that involves hypoxia, inflammation, neoinnervation, accelerated catabolism, and reduction in water and glycosaminoglycan content…

Cannabidiol (CBD) is the major nonpsychotropic phytocannabinoid of Cannabis sativa (up to 40% of Cannabis extracts). Contrary to most cannabinoids, CBD does not produce psychotomimetic or cognitive effects. Interesting, in the last years it has been suggest that CBD produces a plethora of others pharmacological effects, including antioxidant, neuroprotective, anti-proliferative, anti-anxiety, hypnotic and antiepileptic, anti-nausea, anti-ischemic, anti-hyperalgesic, and anti-inflammatory…

The present study investigated the effects of cannabidiol intradiscal injection in the coccygeal intervertebral disc degeneration induced by the needle puncture model using magnetic resonance imaging (MRI) and histological analyses…

Cannabidiol significantly attenuated the effects of disc injury induced by the needle puncture. Considering that cannabidiol presents an extremely safe profile and is currently being used clinically, these results suggest that this compound could be useful in the treatment of intervertebral disc degeneration.

In summary our study revealed anti-degenerative effects of intradiscal microinjection of CBD 120 nmol. CBD represents one of the most promising candidates present in the Cannabis sativa plant for clinical use due to its remarkable lack of cognitive or psychotomimetic actions.”

Neuroprotective Properties of Cannabigerol in Huntington’s Disease: Studies in R6/2 Mice and 3-Nitropropionate-lesioned Mice.

Posted on September 26, 2014 by David

“Different plant-derived and synthetic cannabinoids have shown to be neuroprotective in experimental models of Huntington’s disease (HD) through cannabinoid receptor-dependent and/or independent mechanisms.

Herein, we studied the effects of cannabigerol (CBG), a nonpsychotropic phytocannabinoid, in 2 different in vivo models of HD.

CBG was extremely active as neuroprotectant in mice intoxicated with 3-nitropropionate (3NP), improving motor deficits and preserving striatal neurons against 3NP toxicity.

In addition, CBG attenuated the reactive microgliosis and the upregulation of proinflammatory markers induced by 3NP, and improved the levels of antioxidant defenses that were also significantly reduced by 3NP.

We also investigated the neuroprotective properties of CBG in R6/2 mice. Treatment with this phytocannabinoid produced a much lower, but significant, recovery in the deteriorated rotarod performance typical of R6/2 mice.

Using HD array analysis, we were able to identify a series of genes linked to this disease (e.g., symplekin, Sin3a, Rcor1, histone deacetylase 2, huntingtin-associated protein 1, δ subunit of the gamma-aminobutyric acid-A receptor (GABA-A), and hippocalcin), whose expression was altered in R6/2 mice but partially normalized by CBG treatment.

We also observed a modest improvement in the gene expression for brain-derived neurotrophic factor (BDNF), insulin-like growth factor-1 (IGF-1), and peroxisome proliferator-activated receptor-γ (PPARγ), which is altered in these mice, as well as a small, but significant, reduction in the aggregation of mutant huntingtin in the striatal parenchyma in CBG-treated animals.

In conclusion, our results open new research avenues for the use of CBG, alone or in combination with other phytocannabinoids or therapies, for the treatment of neurodegenerative diseases such as HD.”

The non-psychotropic plant cannabinoids, cannabidivarin (CBDV) and cannabidiol (CBD), activate and desensitize transient receptor potential vanilloid 1 (TRPV1) channels in vitro: potential for the treatment of neuronal hyperexcitability.

Posted on July 17, 2014 by David

“Epilepsy is the most common neurological disorder, with over 50 million people worldwide affected. Recent evidence suggests that the transient receptor potential cation channel subfamily V member 1 (TRPV1) may contribute to the onset and progression of some forms of epilepsy.

Since the two non-psychotropic cannabinoids cannabidivarin (CBDV) and cannabidiol (CBD) exert anticonvulsant activity in vivo and produce TRPV1-mediated intracellular calcium elevation in vitro, we evaluated the effects of these two compounds on TRPV1 channel activation and desensitization and in an in vitro model of epileptiform activity.

These data suggest that CBDV anti-epileptiform effects in the Mg2+-free model are not uniquely mediated via activation of TRPV1. However, TRPV1 was strongly phosphorylated (and hence likely sensitized) in Mg2+-free solution-treated hippocampal tissue, and both capsaicin and CBDV caused TRPV1 dephosphorylation, consistent with TRPV1 desensitization. We propose that CBDV effects on TRP channels should be studied further in different in vitro and in vivo models of epilepsy.”

Marijuana Compound CBD Can Effectively Treat Schizophrenia

Posted on June 25, 2014 by David

Marijuana Plant

“Cannabidiol (CBD) is a known marijuana compound, and might just be better than antipsychotics at treating schizophrenia.

A preliminary trial has shown this form of treatment to have fewer side effects than traditional methods of treatment…

Since CBD comes from the marijuana plant, political issues are likely to compromise its availability. Extracting the compound from the plant is also expensive.

But the biggest issue scientists face is that CBD is a natural compound, and can’t be patented the way new drugs are. Pharmaceutical companies are therefore not likely to develop it.”

Cannabinoids Can Limit Neurological Stroke Damage

Posted on June 24, 2014 by David

“Chemical compounds found in cannabis may help to reduce brain damage following a stroke, new research has revealed.

Researchers at the University of Nottingham conducted a meta-analysis of experimental studies into cannabinoids; chemicals related to those found in cannabis, some of which also occur naturally in the body. The findings showed that the compounds could reduce the size of stroke and improve neurological function.

Cannabinoids can be classified into those found naturally in the body (endocannabinoids), those made artificially (synthetic cannabinoids) or those derived from extracts from the plant cannabis sativa (phytocannabinoids).

The research, announced at the annual UK Stroke Forum, indicates that all three classes of cannabinoid could be effective in shrinking the area of the brain affected by stroke and in recovering neurological function.”

Marijuana & Stroke: Pot Compounds Protect Brain, New Meta-Study Shows

Posted on June 24, 2014 by David

“Cannabinoids, chemicals related to those found in cannabis could be effective in restoring neurological function by shrinking the area of the brain affected by stroke, according to a new study led by Dr. Tim England, Honorary Consultant Stroke Physician at the University of Nottingham and Royal Derby Hospital.

Stroke, a leading cause of adult disability in the UK leaves over half of all survivors dependent on others for life. Over one million people are living with the effects of stroke and it is reported that in the UK alone, over 150,000 people have a stroke every year. Finding new treatments to help survivors recover quickly has never been more important.

The authors examined 94 studies evaluating the effects of cannabinoids on 1022 mice, monkeys, and male rats. Cannabinoids can be classified into endocannabinoids that occur naturally in the body, phytocannabinoids that are obtained from plant extracts, and synthetic cannabinoids.

A meta-analysis of experimental studies conducted by the researchers at the University of Nottingham identifies the potential of all three categories of these compounds potential to reduce brain damage caused by stroke and help improve brain function after an attack.

The U.S. government sought a patent in 2001 for the naturally occuring marijuana molecule, cannabidiol, for use as a brain protector during stroke. ”
