Integrating Endocannabinoid Signaling and Cannabinoids into the Biology and Treatment of Posttraumatic Stress Disorder Matthew N. Hill, Patrizia Campolongo, Rachel Yehuda and Sachin Pate Neuropsychopharmacology REVIEWS, 2018, 43, 80–102. doi : 10.1038/npp.2017.162 Exposure to stress is an undeniable, but in most cases surmountable, part of life. However, in certain individuals, exposure to severe or cumulative stressors can lead to an array of pathological conditions including posttraumatic stress disorder (PTSD), characterized by debilitating trauma-related intrusive thoughts, avoidance behaviors, hyperarousal, as well as depressed mood and anxiety. In the context of the rapidly changing political and legal landscape surrounding use of cannabis products in the USA, [...]
Lire la suiteLa maladie d’Alzheimer et le cannabis médical Kalapa Clinic, Barcelone, Espagne By Alexandra|24,09, 2020 La maladie d’Alzheimer neurodégénérative est la forme la plus courante de démence, qui survient généralement chez les personnes âgées de plus de 65 ans. Environ 24 millions de personnes dans le monde souffrent de cette maladie, qui porte le nom du médecin Alois Alzheimer. Il a décrit la maladie pour la première fois en 1906. La maladie d’Alzheimer : Que se passe-t-il dans le cerveau? Chez les patients atteints de la maladie d’Alzheimer, les cellules nerveuses du cerveau meurent progressivement, ce qui entraîne un rétrécissement du cerveau pouvant aller jusqu’à 20 [...]

Plagued by false starts, a few dashed hopes, but with perhaps a glimmer of light on the horizon, the race to find an effective treatment for COVID-19 continues. At last count, more than 300 treatments and 200 vaccines were in preclinical or clinical development (not to mention the numerous existing agents that are being evaluated for repurposing). There is also a renewed interest in cannabinoid therapeutics — in particular, the nonpsychoactive agent cannabidiol (CBD) and the prospect of [...]
Lire la suiteFDA Approves Clinical Trials for Cannabinoid Drug Designed to Reduce COVID Lung Inflammation Ralph Ellis Medscape, August 21, 2020 The US Food and Drug Administration has approved phase one clinical trials for a synthetic cannabinoid drug designed to treat acute respiratory distress syndrome (ARDS), a life-threatening lung condition which may occur in severe cases of the novel coronavirus, Forbes reported. ARDS can be triggered by over-creation of cytokines, proteins which tell the body to produce more inflammation, Forbes said. The drug going to clinical trials, ARDS-003, would “dampen the cytokine release" and prevent development of ARDS, Tetra Bio-Pharma company CEO and chief regulatory officer Guy Chamberland, MD, [...]

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.

Cancer is a deadly disease; it is estimated that it will cause over 80 thousand deaths in 2019 in Canada. Although numerous studies have demonstrated that cannabinoids have anti-tumorous properties in various cancers, the anti-malignant activities of cannabinol (CBN) on carcinogenesis and underlying mechanisms remain largely unknown. In this study, we [...]

In previous work, we have shown that breast cancer MCF-7 cells, selected by their response to inflammatory IL-1 cytokine, acquire a malignant phenotype (6D cells) through an epithelial mesenchymal transition (EMT).We evaluated CBD as a potential inhibitor of this transition and inducer of [...]

Kaplan Cannabis and Cannabinoid Research, 2019, Volume X, Number X Doi : 10.1089/can.2018.0073 Abstract Introduction : Cannabidiol (CBD) as Epidiolex (GW Pharmaceuticals) was recently approved by the U.S. Food and Drug Administration (FDA) to treat rare forms of epilepsy in patients 2 years of age and older. Together with the increased societal acceptance of recreational cannabis and CBD oil for putative medical use in many states, the exposure to CBD is increasing, even though all of its biological effects are not understood. Once such example is the ability of CBD to be anti-inflammatory and [...]
