Activation of CB1R Promotes Lipopolysaccharide-Induced IL-10 Secretion by Monocytic Myeloid-Derived Suppressive Cells and Reduces Acute Inflammation and Organ Injury, Jérémie Joffre et al., 2020,

Activation of CB1R Promotes Lipopolysaccharide-Induced IL-10 Secretion by Monocytic Myeloid-Derived Suppressive Cells and Reduces Acute Inflammation and Organ Injury Jérémie Joffre, Che-Chung Yeh, Erika Wong, Mayuri Thete, Fengyun Xu, Ivana Zlatanova, Elliot Lloyd, Lester Kobzik, Matthieu Legrand, and Judith Hellman The Journal of Immunology, 2020, 204: 1–20. doi : 10.4049/jimmunol.2000213   Cannabis sativa and its principal components, D9-tetrahydrocannabinol (D9-THC) and cannabidiol, are increasingly being used to treat a variety of medical problems, including inflammatory conditions. Although studies suggest that the endocannabinoid system has immunomodulatory properties, there remains a paucity of information on the effects of cannabinoids on immunity and on outcomes of infection and injury.

Totality of the Evidence Suggests Prenatal Cannabis Exposure Does Not Lead to Cognitive Impairments : A Systematic and Critical Review, Ciara A. Torres et al., 2020

Totality of the Evidence Suggests Prenatal Cannabis Exposure Does Not Lead to Cognitive Impairments : A Systematic and Critical Review Ciara A. Torres, Christopher Medina-Kirchner, Kate Y. O'Malley and Carl L. Hardt Frontiers in Psychology, 2020, Vol 11, Art 816, 1-28. Doi : 10.3389/fpsyg.2020.00816   Background: Despite limited data demonstrating pronounced negative effects of prenatal cannabis exposure, popular opinion and public policies still reflect the belief that cannabis is fetotoxic. Methods: This article provides a critical review of results from longitudinal studies examining the impact of prenatal cannabis exposure on multiple domains of cognitive functioning in individuals aged 0 to 22 years. A literature search was [...]

The Therapeutic Effectiveness of Full Spectrum Hemp Oil Using a Chronic Neuropathic Pain Model, Jacob M. Vigil et al., 2020

The Therapeutic Effectiveness of Full Spectrum Hemp Oil Using a Chronic Neuropathic Pain Model Jacob M. Vigil, Marena A. Montera, Nathan S. Pentkowski, Jegason P. Diviant, Joaquin Orozco, Anthony L. Ortiz, Lawrence J. Rael  and Karin N. Westlund Life, 2020, 10, 69, 1-12 doi : 10.3390/life10050069   Abstract : Background : Few models exist that can control for placebo and expectancy effects commonly observed in clinical trials measuring ‘Cannabis’ pharmacodynamics. We used the Foramen Rotundum Inflammatory Constriction Trigeminal Infraorbital Nerve injury (FRICT-ION) model to measure the effect of “full-spectrum” whole plant extracted hemp oil on chronic neuropathic pain sensitivity in mice. Methods : Male BALBc mice were [...]

Beneficial effects of the phytocannabinoid Δ9-THCV in L-DOPA-induced dyskinesia in Parkinson’s disease, Isabel Espadas et al., 2020

Beneficial effects of the phytocannabinoid Δ9-THCV in L-DOPA-induced dyskinesia in Parkinson's disease Isabel Espadas, Ettel Keifman, Cristina Palomo-Garo Sonia Burgaz, Concepción García, Javier Fernández-Ruiz, Rosario Moratalla Neurobiology of Disease, 2020, 141, 104892 doi : 10.1016/j.nbd.2020.104892   A B S T R A C T The antioxidant and CB2 receptor agonist properties of Δ9-tetrahydrocannabivarin (Δ9-THCV) afforded neuroprotection in experimental Parkinson's disease (PD), whereas its CB1 receptor antagonist profile at doses lower than 5 mg/kg caused anti-hypokinetic effects. In the present study, we investigated the anti dyskinetic potential of Δ9-THCV (administered i.p. at 2 mg/kg for two weeks), which had not been investigated before. This objective was investigated [...]

Prescription of a THC/CBD-Based Medication to Patients with Dementia : A Pilot Study in Geneva, Barbara Broers et al., 2019

Prescription of a THC/CBD-Based Medication to Patients with Dementia : A Pilot Study in Geneva Barbara Broers, Zacharie Patà, Aline Mina, James Wampfler, Christian de Saussure, Sophie Pautex Medical Cannabis & Cannabinoids, 2019, 2, 56–59 Doi : 10.1159/000498924 Abstract Background : Dementia is increasing worldwide. No effective medication is currently available for the treatment of the underlying disease and accompanying behavioral symptoms. Cannabinoids might have a beneficial effect, but clinical studies with (low-dose) synthetic THC have not been conclusive. Objective : To test the acceptability, practical aspects, and clinical outcomes of the introduction of a THC/ CBD-based oral medication in severely demented patients in a specialized [...]

A B S T R A C T Ketamine, a general anaesthetic and psychotomimetic drug, exerts rapid, potent and long-lasting antidepressant effect, albeit the cellular and molecular mechanisms of this action are yet to be discovered. Besides targeting neuronal NMDARs fundamental for synaptic transmission, ketamine affects the [...]
