Neuroprotective Effect of Cannabidiol Against Hydrogen Peroxide in Hippocampal Neuron Culture, Jungnam Kim et al., 2021

Neuroprotective Effect of Cannabidiol Against Hydrogen Peroxide in Hippocampal Neuron Culture Jungnam Kim, Ji Yu Choi, Jeongyeon Seo, and Insung S. Choi Cannabis and Cannabinoid Research, 2021, Volume 6, Number 1, 40-48. Doi : 10.1089/can.2019.0102   Abstract Introduction : Reports on the neurotoxic and neuroprotective effects of cannabidiol (CBD) have not been in complete accord, showing different and somewhat contradictory results depending upon the brain cell types and experimental conditions employed. This work systematically examines the neuroprotective capability of CBD against oxidative stress (i.e., hydrogen peroxide [H2O2]) as well as its toxicity profile in the in vitro culture platform of primary hippocampal neurons. Materials and Methods : [...]

Protective Effects of Cannabidivarin and Cannabigerol on Cells of the Blood–Brain Barrier Under Ischemic Conditions, Nicole L. Stone et al., 2021

Protective Effects of Cannabidivarin and Cannabigerol on Cells of the Blood–Brain Barrier Under Ischemic Conditions Nicole L. Stone, Timothy J. England, and Saoirse E. O’Sullivan Cannabis and Cannabinoid Research, 2021, Doi : 10.1089/can.2020.0159   Abstract Background and Objectives : Preclinical studies have shown cannabidiol is protective in models of ischemic stroke. Based on results from our recent systematic review, we investigated the effects of two promising neuroprotective phytocannabinoids, cannabigerol (CBG) and cannabidivarin (CBDV), on cells of the blood–brain barrier (BBB), namely human brain microvascular endothelial cells (HBMECs), pericytes, and astrocytes. Experimental Approach : Cultures were subjected to oxygen-glucose deprivation (OGD) protocol to model ischemic stroke and cell [...]

Neuroprotection Following Concussion : The Potential Role for Cannabidiol, Jyotpal Singh, John Patrick Neary, 2020

Neuroprotection Following Concussion : The Potential Role for Cannabidiol Jyotpal Singh, John Patrick Neary Canadian Journal of Neurological Sciences, 2020,  1–12 doi : 10.1017/cjn.2020.23   ABSTRACT : Cannabidiol (CBD) has been generating increasing interest in medicine due to its therapeutic properties and an apparent lack of negative side effects. Research has suggested that high dosages of CBD can be taken acutely and chronically with little to no risk. This review focuses on the neuroprotective effects of a CBD, with an emphasis on its implications for recovering from a mild traumatic brain injury (TBI) or concussion. CBD has been shown to influence the endocannabinoid system, both by [...]

La maladie d’Alzheimer et le cannabis médical, Kalapa Clinic, 24/09/2020

La 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 [...]

Research Progress of the Antiviral Bioactivities of Natural Flavonoids, Lin Wang et al., 2020

Research Progress of the Antiviral Bioactivities of Natural Flavonoids Lin Wang · Junke Song · Ailin Liu · Bin Xiao · Sha Li · Zhang Wen · Yang Lu · Guanhua Du Natural Products and Bioprospecting, 2020, 10, 271–283 doi : 10.1007/s13659-020-00257-x Abstract Flavonoids are now considered as an indispensable component in a variety of nutraceutical and pharmaceutical applications. Most recent researches have focused on the health aspects of flavonoids for humans. Especially, different flavonoids have been investigated for their potential antiviral activities, and several natural flavonoids exhibited significant antiviral properties both in vitro and in vivo. This review provides a survey of the literature [...]

New Data Show No Link Between Cannabis and Stroke Sue Hughes, Medscape.com, June 09, 2020

New Data Show No Link Between Cannabis and Stroke Sue Hughes Medscape.com, June 09, 2020 https://www.medscape.com/viewarticle/931988_print A new study that used admission urine toxicology tests to ascertain drug use found no independent association between recent cannabis use and the incidence of acute ischemic stroke. "Previous studies have shown conflicting data on cannabis use and stroke. Our study is a step forward in that we had quite a large population and we had an objective measure of marijuana use with the urine screen, whereas some previous studies have just relied on asking the patient about marijuana use," senior author Shreyas Gangadhara, MD, University of Mississippi Medical Center, Jackson, [...]

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.

Cannabinoids Rescue Cocaine-Induced Seizures by Restoring Brain Glycine Receptor Dysfunction, Guichang Zou et al., 2020

Cannabinoids Rescue Cocaine-Induced Seizures by Restoring Brain Glycine Receptor Dysfunction Guichang Zou, Xin Zuo, Kai Chen, ..., Guangming Huang, Dan Liu, Wei Xiong Cell Reports, 2020, 30, 4209–4219 Doi : 10.1016/j.celrep.2020.02.106   In Brief Zou et al. identify the glycine receptor as a potential therapeutic target for cannabinoids in treating cocaine-induced seizures. The function of extra-synaptic glycine receptors in the prefrontal cortex and hippocampus is impaired by cocaine and rescued by cannabinoids, therefore leading to the therapeutic effects of cannabinoids in treating cocaine-induced seizures. Highlights Cannabinoids alleviate cocaine-induced seizures (CISs) by glycine receptors (GlyRs) Cannabinoid docking reduces hydrogen-bonding interaction between cocaine and GlyRs The prefrontal cortex and hippocampus [...]

Endocannabinoids : A Promising Impact for Traumatic Brain Injury, Lesley D. Schurman et al., 2017

Endocannabinoids : A Promising Impact for Traumatic Brain Injury Lesley D. Schurman and Aron H. Lichtman Frontiers in Pharmacology, 2017. doi: 10.3389/fphar.2017.00069   The endogenous cannabinoid (endocannabinoid) system regulates a diverse array of physiological processes and unsurprisingly possesses considerable potential targets for the potential treatment of numerous disease states, including two receptors (i.e., CB1 and CB2 receptors) and enzymes regulating their endogenous ligands N-arachidonoylethanolamine (anandamide) and 2-arachidonyl glycerol (2-AG). Increases in brain levels of endocannabinoids to pathogenic events suggest this system plays a role in compensatory repair mechanisms. Traumatic brain injury (TBI) pathology remains mostly refractory to currently available drugs, perhaps due to its heterogeneous [...]
