Phytochemicals like terpenes and flavonoids could be beneficial to brain health

Chemokines and cytokines produced at plaques are not blood derived, but are produced by local neurons and glia . However, while microglia are involved in the metabolism and clearance of β amyloid, it isn’t known whether microglial reactivity and inflammation is a cause or consequence of β-amyloid accumulation. It is known that in animal models the build up of β-amyloid can be dissociated how to get into the trades from neuronal damage by blocking microglial activation and that β-amyloid itself can induce microglial reactivity . Therefore, it is plausible that reactive microglia are central to the neurodegenerative cascade in Alzheimer’s. For instance, release of TNF-α from microglia can stimulate glutamate release from astrocytes, which may contribute to NMDA-receptor mediated neurotoxicity .

On the balance of evidence, CB2 appears to be such a target, with the potential to both help improve outcomes in chronic neuroinflammatory conditions, and to reduce secondary damage following acute injury. The side-effect profile for CB2 agonism also appears to be benign, with no adverse effects currently known. It therefore appears likely that following forex trading strategies for the winning trader the eagerly awaited development of potent CB2-selective agonists, phase I clinical trials will quickly follow. Very recently, CB2 activation with O-3853 and O-1966 (47-fold and 218-fold selective for CB2 over CB1 respectively) has been shown to reduce infarct size in mouse brains 24 hrs after induction of focal ischemia and reperfusion by up to 30% .

The same variation of CB2 expression was also observed in microglia at the various stages of activation. This pattern of CB2 expression in microglia has since been repeated in subsequent studies, and may have important implications for drugs targeting CB2 at various stages of microglial activation . Most recently, Maresz et al. have demonstrated that the combination of IFN-γ and granulocyte mononuclear colony stimulating factor (GM-CSF) induces even higher levels of microglial CB2. Alzheimer’s disease was considered an inflammatory pathology early last century by Alzheimer and other German histopathologists. This view has been rekindled by the observation that microglia cluster at β-amyloid plaques in Alzheimer’s diseased brains . The distribution of reactive microglia correlates with areas of neuronal loss in animal models of Alzheimer’s disease , and inflammation is known to be involved in the pathogenic cascade.

CB2 activation also suppresses neutrophil migration and differentiation , but induces natural killer cell migration . But as CBD oil scrubs up and goes mainstream, it is not easy to tell which products stand up to scrutiny. The consensus among dermatologists and dieticians is that while phytocannabinoids – cannabinoids produced in plants – are indeed exciting ingredients, there is a huge amount of confusion among consumers, on which some brands are cashing in.

• In vivo studies using CB2 selective antagonists, CB2 siRNA, or CB2 -/- mice are still scarce.
• Foreign companies which are registered in Italy are allowed to open a Qonto account if the headquarter is based in France, Germany or Spain.
• In many U.S. states, cannabis dispensaries were designated as essential businesses.
• In addition, partial agonists are often advantageous for drug therapies because they can lead to decreased levels of tolerance and desensitization compared with full agonists.

The volume of this secondary area of cell death can be considerable, and has the potential for pharmacological intervention. Importantly, the therapeutic window appears to extend for many hours and even days following injury. Therefore, pathways which may inhibit neurotoxic inflammatory processes (and/or promote neuroprotective immune functions) are attractive targets for drug development.

One promising compound is GW405833, a highly selective partial agonist for the CB2 receptor. GW has a 1200-fold selectivity for human CB2 receptors (80-fold for rat CB2), and reduces forskolin-induced cAMP accumulation by approximately 45% (~75% for CP 55,940). Despite being a partial agonist, GW has proven to be a potent inhibitor of hyperalgesia in a number of inflammatory and chronic pain rodent models . Importantly, these effects reach a maximum at approximately 1 mg/kg in rodents, whereas CB1-mediated psychoactive effects such as loss of motor coordination are only observed at extremely high doses.

• The consensus among dermatologists and dieticians is that while phytocannabinoids – cannabinoids produced in plants – are indeed exciting ingredients, there is a huge amount of confusion among consumers, on which some brands are cashing in.
• Sativex is a drug that combines Δ9-THC and cannabidiol derived from cultivated cannabis, and has been approved in Canada for the treatment of neuropathic pain in patients with multiple sclerosis .
• This has been supported in recent years by demonstrations that CB2 regulates inflammation in a diverse range of animal models, a small sample of which includes gastro-intestinal inflammation , acute hindpaw inflammation , and pulmonary inflammation .
• Brain injury also activates microglia in a secondary inflammatory phase of more widespread damage.
• Third, drugs that activate CB1 can have unwanted psychoactive effects at moderate to high doses, whereas CB2 receptors are not psychoactive .

Still, there are plenty of opportunities to introduce these products legally in both markets. “PR for cannabis is similar to PR for alcohol and fashion, but with cannabis being illegal in New York, the nation’s media capital, it means you can’t demo product like you normally would when launching a product or sharing new releases,” says Hendrix. Recreational cannabis retailers in tourist destinations such as Las Vegas saw their customer traffic dwindle, causing some of these dispensaries to start focusing on home delivery. In the medical segment, people delayed doctor visits, causing new patient starts to drop.

The legalization of recreational cannabis has been steadily rising in the U.S., and with that comes an influx of emerging brands and related products. Heightened consumer awareness, along with de-stigmatization and withering stereotypes, are giving innovative companies a platform for success. Still, the cannabis space is a new frontier for publicists and marketing execs to navigate through. We spoke with a few companies who shared how cannabis is disrupting business as usual in the communications realm, and how marketing and PR is overcoming those challenges to help the cannabis category thrive.

However, in only the last few years, a number of impressive studies have been published on the therapeutic effects of CB2 stimulation. Chief among these for neuroinflammation has been the experiments of Ramirez et al. on the effects of CB2 stimulation in a model of Alzheimer’s disease. In bone tissue, CB2 receptors stimulate osteoblast function and inhibit osteoclasts, leading to increased bone thickness . Potentially useful for osteoporosis, this also has the promise to help control key mechanisms involved in the generation of pain in bone cancer . CB2 stimulation also reverses various types of hyperalgesia in animal models , inhibits emesis , retards the progression of atherosclerosis in a rodent model , and has anti-angiogenic and anti-tumourogenic effects in several cancer models . In a rat chronic lesion model of Huntington’s disease, Fernandez-Ruiz et al. found that CB2 expression was upregu-lated in subpopulations of microglia in the lesioned striatum.

Microglia may be either neuroprotective or neurotoxic, depending upon the type and extent of exogenous or endogenous stimuli they receive and the phenotype they assume . For instance, in nerve transection models of glutamate injury, microglial activity is central to the healing response . By contrast, IFN-γ primed microglia then treated with LPS will adopt a phenotype adapted for defensive immunity, and hence cytotoxicity. When microglia are not reactive for defensive immune functions, however, they do not release inflammatory cytokines.

Endocannabinoids are released following brain injury and may protect against excitotoxic damage during the acute stage of injury. Brain injury also activates microglia in a secondary inflammatory phase of more widespread damage. Most drugs targeting the acute stage are not effective if administered more than 6 hours after injury. Therefore, drugs targeting microglia later in the neurodegenerative cascade are desirable. We have found that cannabinoid CB2 receptors are up-regulated during the activation of microglia following brain injury. Specifically, CB2-positive cells appear in the rat brain following both hypoxia-ischemia and middle cerebral artery occlusion .

These authors suggest that neuroprotective properties of Δ9-THC in Huntington’s disease might be mediated by CB2 . Recently, controversial work has been published that describes widespread CB2 expression in CNS neuronal beds . However, in our own work we have been unable to replicate these results, and have evidence only for the absence of CB2 from non-glial/non-endothelial cells in the brain. The same research group has recently published findings showing a virtual absence of CB2 mRNA from the CNS outside of the brainstem and hypothalamus , although they have argued for CB2 regulation of stress mediated depression .
