Antidepressant-like effects of β-caryophyllene on restraint plus stress-induced depression, Eun-Sang Hwang et al., 2020

Antidepressant-like effects of β-caryophyllene on restraint plus stress-induced depression Eun-Sang Hwang, Hyun-Bum Kim, Seok Lee, Min-Jeong Kim, Kwan-Joong Kim, Gaeul Han, Se-Young Han, Eun-A Lee, Jeong-Hee Yoon, Dae-Ok Kim, Sungho Maeng, Ji-Ho Park Behavioural Brain Research, 2020, 380, 112439 doi : 10.1016/j.bbr.2019.112439   A B S T R A C T Chronic stress is depressogenic by altering neurotrophic and neuroinflammatory environments of the organism. The endocannabinoid system controls cognitive and emotional responses related with stress through the interaction with endocannabinoid receptors. β-Caryophyllene (BCP) is a CB2 agonist that exhibited anti-inflammatory, analgesic effects but minimal psychoactive effects.

Bibliographie : Cannabis et Troubles cardio-vasculaires

Bibliographie Cannabis et Troubles cardio-vasculaires   Dr Christian SUEUR, GRECC, 2e édition, janvier 2020.   Actuellement, les méta-analyses ne montrent pas d'augmentation significative des pathologies cardiovasculaire chez les consommateurs de cannabis. (cf en particulier la méta-analyse de Divya RAVI et coll., Annals of Internal Medicine, 2018). Quoiqu'il en soit, l'existence de facteurs de risques liés à la consommation de cannabis fumé est semble-t-il incontestable; de même, les risques sont vraisemblablement augmentés chez les sujets prédisposés, présentant des pathologies cariaques, vasculaires, des troubles de l'excitabilité cardiaque ou de la tension artérielle. La plupart des "Case Report" consistent en des accidents par sténose vasculaire, cérébrale ou cardiaque, [...]

Beta-Caryophyllene, a CB2-Receptor-Selective Phytocannabinoid, Suppresses Mechanical Allodynia in a Mouse Model of Antiretroviral-Induced Neuropathic Pain Esraa Aly, Maitham A. Khajah and Willias Masocha Molecules, 2020, 25, 106; doi:10.3390/molecules25010106   Abstract : Neuropathic pain associated with nucleoside reverse transcriptase inhibitors (NRTIs), therapeutic agents for human immunodeficiency virus (HIV), responds poorly to available drugs. Smoked cannabis was reported to relieve HIV-associated neuropathic pain in clinical trials. Some constituents of cannabis (Cannabis sativa) activate cannabinoid type 1 (CB1) and cannabinoid type 2 (CB2) receptors. However, activation of the CB1 receptor is associated with side eects such as psychosis and physical dependence. Therefore, we investigated the effect of B-caryophyllene (BCP), [...]
