Cannabinoid receptor expression in non-small cell lung cancer. Effectiveness of tetrahydrocannabinol and cannabidiol inhibiting cell proliferation and epithelial mesenchymal transition in vitro Lara Milian, Manuel Mata, Javier Alcacer, Marıa Oliver, Marıa Sancho-Tello, Jose Javier Martın de Llano, Carlos Camps, Jose Galbis, Julian Carretero, Carmen Carda PLoS ONE, 2020, 15, (2): e0228909. Doi : 10.1371/journal.pone.0228909 Abstract Background/Objective : Patients with non-small cell lung cancer (NSCLC) develop resistance to antitumor agents by mechanisms that involve the epithelial-to-mesenchymal transition (EMT). This necessitates the development of new complementary drugs, e.g., cannabinoid receptors (CB1 and CB2) agonists including tetrahydro-cannabinol (THC) and cannabidiol (CBD). The combined use of THC and CBD [...]

CBD was a safe and well tolerated medication for this patient. Upon treatment with CBD and [...]
Lire la suiteThe effects of cannabinoid 1 receptor compounds on memory : a meta-analysis and systematic review across species Faith Borgan, Katherine Beck, Emma Butler, Robert McCutcheon, Mattia Veronese, Anthony Vernon, Oliver D. Howes Psychopharmacology, 2019 Doi : 10.1007/s00213-019-05283-3 Abstract Rationale : While cannabis-based medicinal products have been shown to be effective for numerous neurological and psychiatric disorders, the evidence base regarding their adverse cognitive effects is poorly understood. The cannabinoid 1 receptor modulates memory performance via intracellular and extracellular mechanisms that alter synaptic transmission and plasticity. While previous literature has consistently shown that chronic cannabis users exhibitmarked cognitive impairments,mixed findings have been reported in the context [...]

Doi : 10.1111/bph.14165 BACKGROUND AND PURPOSE Numerous claims are made for cannabis’ therapeutic utility upon human seizures, but concerns persist about risks. A potential confounder is the presence of both Δ9-tetrahydrocannabinol (THC), variously reported to be pro- and anticonvulsant, and cannabidiol (CBD), widely confirmed as anticonvulsant. Therefore, we investigated effects of prolonged exposure to different THC/CBD cannabis extracts on seizure activity and associated measures of endocannabinoid [...]

Joseph Brand and Zhongzhen Zhao Frontiers in Pharmacology, 2017, vol 8, Article 108, 1-11. doi : 10.3389/fphar.2017.00108 Cannabis sativa L. (Cannabaceae) has a long history of utilization as a fiber and seed crop in China, and its achenes (“seeds”) as well as other plant parts have been recorded in Chinese medical texts for nearly 2000 years. While the primary applications of cannabis in Chinese medicine center around the use of the achenes, ancient indications for the female inflorescence, and other plant parts include conditions such as pain [...]

The European Commission “Proposal for a Council Decision” is meaningful because – if adopted by the Council of Europe – the EU countries would vote as a block at the CND session in Vienna and the three motions [...]

Objective : To summarize the clinical outcomes, study designs and limitations for the use of CBD and nabiximols (whole plant extract from Cannabis sativa L. that has been purified into 1:1 ratio of CBD and delta-9- tetrahydrocannabinol) in the treatment of psychiatric disorders. Materials and method : A systematic review was [...]
Lire la suiteLe cannabidiol, un agent thérapeutique prometteur ? Benjamin Rolland , Mathieu Chappuy, Patrizia Carrieri SWAPS, 3e et 4e trimestre 2019, n° 92-93, , 5-6. Deuxième cannabinoïde le plus étudié après le THC, sans effet psychoactif, le cannabidiol dispose de propriétés thérapeutiques intéressantes, notamment en psychiatrie. Le point sur les recherches La grande famille des cannabinoïdes Les cannabinoïdes sont un ensemble de substances capables d’activer les récepteurs du même nom (« récepteurs cannabinoïdes »). Il existe deux grandes familles de récepteurs cannabinoïdes, CB1 et CB2. Dans le système nerveux central, c’est surtout CB1 qui est exprimé, alors que CB2 est principalement présent dans le système immunitaire. [...]

Il est presque identique dans sa structure au THC mais est 33 fois plus fort que lui, ainsi que du CBDP, le dérivé correspondant du CBD. La recherche pourrait permettre de développer de futures souches de THCP beaucoup plus puissantes. Jusqu’à présent, près de 150 phytocannabinoïdes ont été détectés dans la plante de cannabis, bien que [...]

Doi : 10.1186/s12888-019-2409-8 Abstract Background : Medicinal cannabis has received increased research attention over recent years due to loosening global regulatory changes. Medicinal cannabis has been reported to have potential efficacy in reducing pain, muscle spasticity, chemotherapy-induced nausea and vomiting, and intractable childhood epilepsy. Yet its potential application in the field of psychiatry is lesser known. Methods : The first clinically-focused systematic review on the emerging medical application of cannabis across all major psychiatric disorders was conducted. Current evidence regarding [...]
