Cannabinoid CB2 receptor stimulation attenuates brain edema and neurological deficits in a germinal matrix hemorrhage rat model.

“Germinal matrix hemorrhage (GMH) is one of the most common and devastating cerebrovascular events that affect premature infants, resulting in a significant socioeconomic burden. However, GMH has been largely unpreventable, and clinical treatments are mostly inadequate.

In the present study, we tested the hypothesis that a selective CB2 receptor agonist, could attenuate brain injury and neurological deficits…

This current study suggests a potential clinical utility for CB2R agonists as a potential therapy to reduce neurological injury and improve patient outcomes after GMH.”

Regulation of inflammation and proliferation of human bladder carcinoma cells by type-1 and type-2 cannabinoid receptors.

“Pro-inflammatory cytokines, growth and angiogenic factors released by leukocytes are involved in carcinogenesis and cancer progression, but they are also crucial for fighting tumour growth and spreading.

We have previously demonstrated that endocannabinoids modulate cell-to-cell crosstalk during inflammation. Here, we investigated the inflammatory and tumourigenic properties of endocannabinoids in a human urinary bladdercarcinoma cell line…

Collectively, these findings suggest that CB receptors may play distinct roles in cancer biology, depending on the specific ligand employed.

CONCLUSIONS:

The in vivo assessment of the role of CB receptors in inflammation and cancer might be instrumental in broadening the understanding about bladder cancer biology.”

Association Between Cannabis Use and the Risk of Bladder Cancer: Results From the California Men’s Health Study.

“To investigate the association of cannabis use and tobacco smoking on the incidence of bladder cancer within the California Men’s Health Study cohort…

…using tobacco only was associated with an increased risk of bladder cancer, whereas cannabis use only was associated with a 45% reduction in bladder cancer incidence.

Although a cause and effect relationship has not been established, cannabis use may be inversely associated with bladder cancer risk in this population.”

New insights into antimetastatic and antiangiogenic effects of cannabinoids.

“Cannabinoids exert antitumorigenic effects via multiple mechanisms.

Of these, antimetastatic and antiangiogenic actions have attracted considerable interest in the past years…

This chapter reviews the cell- and substance-specific antitumorigenic mechanisms of cannabinoids with particular consideration of their antimetastatic/anti-invasive and antiangiogenic actions.

In addition, beneficial interactions of cannabinoids with currently used chemotherapeutics as well as the influence of cannabinoids on tumor-immune surveillance are addressed.

Collectively, the currently available data suggest cannabinoids as a potential tool in modern cancer pharmacotherapy.”

Cannabidiol Attenuates Sensorimotor Gating Disruption and Molecular Changes Induced by Chronic Antagonism of NMDA receptors in Mice.

“Preclinical and clinical data suggest that cannabidiol (CBD), a major non-psychotomimetic compound from Cannabis sativa, induces antipsychotic-like effects…

These results indicate that repeated treatment with CBD, similar to clozapine, reverses the psychotomimetic-like effects and attenuates molecular changes observed after chronic administration of an NMDAR antagonist.

These data support the view that CBD may have antipsychotic properties.”  http://www.ncbi.nlm.nih.gov/pubmed/25618402

“Cannabidiol, a Cannabis sativa constituent, as an antipsychotic drug… a controlled clinical trial comparing CBD with an atypical antipsychotic drug have confirmed that this cannabinoid can be a safe and well-tolerated alternative treatment for schizophrenia.” http://www.ncbi.nlm.nih.gov/pubmed/16612464

“A critical review of the antipsychotic effects of cannabidiol: 30 years of a translational investigation… These results support the idea that CBD may be a future therapeutic option in psychosis, in general and in schizophrenia, in particular.” http://www.ncbi.nlm.nih.gov/pubmed/22716160

The effects of Δ9-tetrahydrocannabinol and cannabidiol alone and in combination on damage, inflammation and in vitro motility disturbances in rat colitis

“Cannabis is taken as self-medication by patients with inflammatory bowel disease for symptomatic relief.

Cannabinoid receptor agonists decrease inflammation in animal models of colitis, but their effects on the disturbed motility is not known. (-)-Cannabidiol (CBD) has been shown to interact with Δ9-tetrahydrocannabinol (THC) in behavioural studies, but it remains to be established if these cannabinoids interact in vivo in inflammatory disorders.

Therefore the effects of CBD and THC alone and in combination were investigated in a model of colitis…

In this model of colitis, THC and CBD not only reduced inflammation but also lowered the occurrence of functional disturbances. Moreover the combination of CBD and THC could be beneficial therapeutically, via additive or potentiating effects.

As the two phytocannabinoids modulate the immune system and differ in their pharmacological profile, their combination could be more beneficial than either drug alone. Additionally CBD could not only potentiate the therapeutic effects of THC, but also attenuate some of its undesirable effects…”

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

“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.”

Cannabidiol protects against doxorubicin-induced cardiomyopathy by modulating mitochondrial function and biogenesis.

“Doxorubicin (DOX) is a widely used, potent chemotherapeutic agent; however, its clinical application is limited because of its dose-dependent cardiotoxicity. DOX’s cardiotoxicity involves increased oxidative/nitrative stress, impaired mitochondrial function in cardiomyocytes/endothelial cells, and cell death.

Cannabidiol is a non-psychotropic constituent of marijuana, which is well-tolerated in humans, with antioxidant, anti-inflammatory, and recently discovered antitumor properties.

We aimed to explore the effects of cannabidiol in a well-established mouse model of DOX-induced cardiomyopathy…

Treatment with cannabidiol markedly improved DOX-induced cardiac dysfunction, oxidative/nitrative stress and cell death. Cannabidiol also enhanced the DOX-induced impaired cardiac mitochondrial function and biogenesis.

These data suggest that cannabidiol may represent a novel cardioprotective strategy against DOX-induced cardiotoxicity, and the above described effects on mitochondrial function and biogenesis may contribute to its beneficial properties described in numerous other models of tissue injury.”
