“Nabiximols (Sativex® ) is a cannabinoid-based compound used for the treatment of moderate to severe spasticity in multiple sclerosis (MS). The aim of the study is to investigate the effect of the administration of Nabiximols on blood transcriptome profile of MS patients and to interpret it in the context of pathways and networks.
Our findings support the immunomodulatory activity of cannabinoids in MS patients. Further studies in more specific cell types are needed to refine these results.” https://www.ncbi.nlm.nih.gov/pubmed/29528549 http://onlinelibrary.wiley.com/doi/10.1111/ene.13623/abstract“Cannabinoid compounds suppress immune function, and while this could compromise one’s ability to fight infections, immune suppression is the desired effect for therapies for autoimmune diseases.” https://www.ncbi.nlm.nih.gov/pubmed/29512125

“Activating the endocannabinoid system has become a major focus in the search for novel therapeutics for anxiety and deficits in fear extinction, two defining features of PTSD. We examined whether chronic treatment with the fatty acid amide hydrolase (FAAH) inhibitor URB597 (0.2, 0.3, 0.4 mg/kg, i.p.) or the CB1/2 receptor agonist WIN55,212-2 (0.25, 0.5 mg/kg, i.p.) injected for 3 weeks to rats exposed to the shock and reminders model of PTSD would attenuate post-stress symptoms and affect basolateral amygdala (BLA) and CA1 CB1 receptors.
Exposure to shock and reminders enhanced acoustic startle response and impaired extinction. Rats exposed to shock and reminders and chronically treated with URB597 demonstrated normalized startle response and intact extinction kinetics. WIN55,212-2 only affected the startle response. The therapeutic effects of URB597 and WIN55,212-2 were found to be CB1 receptor dependent, as these effects were blocked when a low dose of the CB1 receptor antagonist AM251 (0.3 mg/kg, i.p. for 3 weeks) was co-administered. Moreover, URB597, but not WIN55,212-2, normalized the shock/reminders-induced upregulation in CB1 receptor levels in the BLA and CA1. One hour after the shock, N-arachidonoylethanolamine (AEA) was increased in the BLA and decreased in the CA1. Circulating 2-arachidonoylglycerol (2-AG) concentrations were decreased in shocked rats, with no significant effect in the BLA or CA1. FAAH activity was increased in the CA1 of shocked rats.
Chronic cannabinoid treatment with URB597 can ameliorate PTSD-like symptoms suggesting FAAH inhibitors as a potentially effective therapeutic strategy for the treatment of disorders associated with inefficient fear coping.”
“Cannabis vaporization is a technology designed to deliver inhaled cannabinoids while avoiding the respiratory hazards of smoking by heating cannabis to a temperature where therapeutically active cannabinoid vapors are produced, but below the point of combustion where noxious pyrolytic byproducts are formed.
This study was designed to evaluate the efficacy of an herbal vaporizer known as the Volcano®, produced by Storz & Bickel GmbH&Co. KG, Tuttlingen, Germany. Three 200 mg samples of standard NIDA cannabis were vaporized at temperatures of 155°–218°C. For comparison, smoke from combusted samples was also tested.
The study consisted of two phases: (1) a quantitative analysis of the solid phase of the vapor using HPLC-DAD-MS (High Performance Liquid Chromatograph-Diode Array-Mass Spectrometry) to determine the amount of cannabinoids delivered; (2) a GC/MS (Gas Chromatograph/ Mass Spectrometer) analysis of the gas phase to analyze the vapor for a wide range of toxins, focusing on pyrene and other polynuculear aromatic hydrocarbons (PAHs).
The HPLC analysis of the vapor found that the Volcano delivered 36%–61% of the THC in the sample, a delivery efficiency that compares favorably to that of marijuana cigarettes.
The GC/MS analysis showed that the gas phase of the vapor consisted overwhelmingly of cannabinoids, with trace amounts of three other compounds. In contrast, over 111 compounds were identified in the combusted smoke, including several known PAHs.
The results indicate that vaporization can deliver therapeutic doses of cannabinoids with a drastic reduction in pyrolytic smoke compounds. Vaporization therefore appears to be an attractive alternative to smoked marijuana for future medical cannabis studies.”
“We have previously shown that i) endocannabinoids (eCB; e.g. anandamide [AEA]) are involved in the maintenance of homeostatic sebaceous lipid production (SLP) in human sebaceous glands (SG); and ii) eCB treatment dramatically increases SLP. Here, we aimed to investigate the expression of the major eCB synthesizing and degrading enzymes, and to study the effects of eCB uptake inhibitors on human SZ95 sebocytes, thus exploring the role of the putative eCB membrane transporter (EMT), which has been hypothesized to facilitate the cellular uptake and subsequent degradation of eCBs. We found that the major eCB synthesizing (NAPE-PLD, DAGLα and -β) and degrading (FAAH, MAGL) enzymes are expressed in SZ95 sebocytes, and also in SGs (except for DAGLα, whose staining was dubious in histological preparations). Interestingly, eCB uptake-inhibition with VDM11 induced a moderate increase in SLP, and also elevated the levels of various eCBs and related acylethanolamides. Finally, we found that VDM11 was able to interfere with the pro-inflammatory action of the Toll-like receptor 4 activator lipopolysaccharide. Collectively, our data suggest that inhibition of eCB uptake exerts anti-inflammatory actions and elevates both SLP and eCB levels; thus, these inhibitors might be beneficial in cutaneous inflammatory conditions accompanied by dry skin.”
