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 [...]
Lire la suiteCette année, nous avions prévu que le 9e colloque international se déroulerait en juin, chez nous, à Strasbourg et qu’il aborderait la thématique de la recherche sur les cannabinoïdes et les cancers. Aux vues des circonstances de ce début d’année 2020, nous avons pris la décision de reporter cet évènement à une date encore inconnue. Nous allons faire au mieux pour maintenir notre programme. Vous trouverez de plus amples détails dans le communiqué ci-dessous.

Byrareddy, Mahesh Mohan Brain, Behavior, and Immunity, 2020, 1-2. doi : 10.1016/j.bbi.2020.04.079 Keywords : SARS-CoV2, Rhesus macaque, Cannabinoids, Inflammation, Cytokine, Lung Coronavirus disease-2019 (COVID-19), caused by Severe Acute Respiratory Syndrome coronoavirus-2 (SARS-CoV2) has emerged as a global pandemic, which was first reported in Wuhan, China. Recent reports have suggested that acute infection is associated with a cytokine superstorm, which contributes to the symptoms of fever, cough, muscle pain and in severe cases bilateral interstitial pneumonia characterized by ground glass opacity and focal chest infiltrates that can [...]

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 [...]

Welling, Lei Liu, Arno Hazekamp, Ashley Dowell, Graham J. King Medical Cannabis & Cannabinoids, 2019, 2, 1–13 Doi : 10.1159/000496868 Abstract The plant genus Cannabis is a prolific producer of unique pharmaceutically relevant metabolites, commonly referred to as cannabinoids. Robust and standardised methods for the quantification of cannabinoids within botanical and drug forms is a critical step forward for an emerging Cannabis- based pharmaceutical industry, which is poised for rapid expansion. Despite a growing body of analytical methods for the quantification of cannabinoids, few have [...]

The ligands of the ECS are the endocannabinoids, whose actions are mimicked by exogenous cannabinoids, such as phytocannabinoids and synthetic cannabinoids. Responses to the ligands of the ECS are mediated by numerous receptors like the classical cannabinoid receptors (CB1 and CB2) as well as ECS-related receptors, e.g., G protein-coupled receptors 18 and 55 (GPR18 and GPR55), transient receptor potential ion channels, and nuclear peroxisome proliferator-activated receptors. The ECS regulatesalmost all levels of [...]
Lire la suiteGPR55-Mediated Effects in Colon Cancer Cell Lines Carina Hasenoehrl, David Feuersinger, Melanie Kienzl, Rudolf Schicho Medical Cannabis & Cannabinoids, 2019, 2, 22–28 Doi : 10.1159/000496356 Abstract The cannabinoid-responsive G protein-coupled receptor GPR55 and its endogenous ligand L-α lyso-phosphatidylinositol (LPI) have been reported to play a role in several cancers. A proliferation-enhancing effect of GPR55 has been described for several cancer cell lines and LPI has been found elevated in cancer patients. The aim of this study was to investigate whether GPR55 signaling had an effect on the proliferation of colon cancer cell lines. Using cell viability assays and Western blotting, we show that stable overexpression [...]
