The Hypocretin/Orexin Receptor-1 as a Novel Target to Modulate Cannabinoid Reward.

Posted on by

“Although there is a high prevalence of users who seek treatment for cannabis dependence, no accepted pharmacologic treatment is available to facilitate and maintain abstinence.

 The hypocretin/orexin system plays a critical role in drug addiction, but the potential participation of this system in the addictive properties of cannabinoids is unknown.

 We investigated…  studies were performed to evaluate dopamine extracellular levels in the nucleus accumbens after acute Δ9-tetrahydrocannabinol administration..

… role of Hcrtr-1 in the reinforcing and motivational properties of WIN55,212-2 (THC) was confirmed…

CONCLUSIONS:

These findings demonstrate that Hcrtr-1 modulates the reinforcing properties of cannabinoids, which could have a clear therapeutic interest.”

Hepatic Cannabinoid Receptor Type 1 Mediates Alcohol-Induced Regulation of Bile Acid Enzyme Genes Expression Via CREBH.

Posted on by

“In this study, we have investigated the effect of alcohol exposure on hepatic bile acid homeostasis and elucidated the mediatory roles of Cb1r and Crebh in this process.

We found that alcohol exposure or Cb1r-agonist 2-AG treatment increases hepatic bile acid synthesis and serum ALT, AST levels in vivo along with significant increase in Crebh gene expression and activation.

 Alcohol exposure activated Cb1r, Crebh, and perturbed bile acid homeostasis…

 Overall, our study demonstrates a novel regulatory mechanism of hepatic bile acid metabolism by alcohol via Cb1r-mediated activation of Crebh, and suggests that targeting Crebh can be of therapeutic potential in ameliorating alcohol-induced perturbation of bile acid homeostasis.”

Palmitoylethanolamide: From endogenous cannabimimetic substance to innovative medicine for the treatment of cannabis dependence.

Posted on by

“Palmitoylethanolamide (PEA) is a fatty acid amide showing some pharmacodynamic similarities with Δ9-tetrahydrocannabinol, the principal psychoactive compound present in the cannabis plant.

Like Δ9-tetrahydrocannabinol, PEA can produce a direct or indirect activation of cannabinoid receptors.

 Furthermore, it acts as an agonist at TRPV1 receptor.

The hypothesis is that PEA has anti-craving effects in cannabis dependent patients, is efficacious in the treatment of withdrawal symptoms, produces a reduction of cannabis consumption and is effective in the prevention of cannabis induced neurotoxicity and neuro-psychiatric disorders.”

Anti-inflammatory activity of topical THC in DNFB-mediated mouse allergic contact dermatitis independent of CB1 and CB2 receptors.

Posted on by

“∆9 -Tetrahydrocannabinol (THC), the active constituent of Cannabis sativa, exerts its biological effects in part through the G-protein-coupled CB1 and CB2 receptors, which were initially discovered in brain and spleen tissue, respectively. However, THC also has CB1/2 receptor-independent effects. Because of its immune-inhibitory potential, THC and related cannabinoids are being considered for the treatment of inflammatory skin diseases.

Here we investigated the mechanism of the anti-inflammatory activity of THC and the role of CB1 and CB2 receptors…

CONCLUSIONS:

Topically applied THC can effectively attenuate contact allergic inflammation by decreasing keratinocyte-derived pro-inflammatory mediators that orchestrate myeloid immune cell infiltration independent of CB1/2 receptors.

This has important implications for the future development of strategies to harness cannabinoids for the treatment of inflammatory skin diseases.”

‘It’s the one medicine we have seen work’: Oregon parents use medical marijuana to help severely autistic son

Posted on by

“Alex Echols has Tuberous Sclerosis, a rare genetic disorder that led to autism and seizures from a young age. Medical marijuana is the only treatment that eased his violent behavior, his parents said.”

An Oregon family has turned to medical marijuana to manage their son's severe autistic rage. Eleven-year-old Alex Echols is severely autistic. 

“Most parents wouldn’t dream of giving their child marijuana. But an Oregon couple says it’s the only thing that’s been able to help their 11-year-old autistic son.”

 

Stanford University Study Finds That Marijuana Could Help With Autism

Posted on by

“A study conducted by Stanford University has found that there might be compounds in marijuana which have some very specific health benefits. The study’s results reveal that cannabinoids – which are found in cannabis – might help to treat autism.”

“A new study shows that mutations associated with autism block the action of brain molecules that act on the same receptors that marijuana’s active chemical acts on,” according to the Autism Daily Newscast. “Thomas Sudhof, a cellular physiologist at Stanford University, tested mutations associated with autism in mice. Two mutations associated with autism in a synapse-adhesion protein led to deficits in prolonged endocannabinoid signaling in mice. This suggests that autism could caused by a disruption of the brain’s ability to send clear signals.

Study Finds Cannabis May Provide Treatment For Autism

Posted on by

“A new study out of Standford University has found promising signs to suggest that cannabinoids – compounds found in cannabis, as well as naturally produced in our body – may help to treat autism.

According to Autism Daily Newscast (ADN); ”A new study shows that mutations associated with autism block the action of brain molecules that act on the same receptors that marijuana’s active chemical acts on”.

They continue: “Thomas Sudhof, a cellular physiologist at Stanford University, tested mutations associated with autism in mice. Two mutations associated with autism in a synapse-adhesion protein led to deficits in prolonged endocannabinoid signaling in mice. This suggests that autism could caused by a disruption of the brain’s ability to send clear signals”.

These findings suggest that cannabinoids could be used as a treatment to autism as they can unblock a disruption in the body’s cannabinoid receptors…”

The Use of Marijuana or Synthetic Cannabinoids for the Treatment of Headache – MedScape

Posted on by

“Pharmacological preparations of cannabinoid compounds have a variety of therapeutic uses in medicine, including different pain syndromes, but have not been previously reported as beneficial for cluster headache.We present a patient with cluster headache who was refractory to multiple acute and preventive medications but successfully aborted his attacks with recreational marijuana use; subsequent use of dronabinol provided equally effective pain relief. The beneficial effect may be related to the high concentration of cannabinoid receptors in the hypothalamus, which has been implicated as a site of dysfunction in neuroimaging studies of patients with cluster headache.

The plant Cannabis sativa has a long history of medical use in the treatment of pain and spasms, the promotion of sleep, and the suppression of nausea and vomiting. However, in the early 1970s cannabis was classified in the Narcotic Acts in countries all over the world as having no therapeutic benefit; therefore, it cannot be prescribed by physicians or dispensed by pharmacists. In the light of this contradictory situation, an increasing number of patients practice a self-prescription with cannabis products for relieving a variety of symptoms.

  The majority of patients used natural cannabis products such as marihuana, hashish, and an alcoholic tincture; in just 5 cases dronabinol (Marinol) was taken by prescription…

 …this survey demonstrates a successful use of cannabis products for the treatment of a multitude of various illnesses and symptoms. This use was usually accompanied only by slight and in general acceptable side effects…”

Effects of anandamide in migraine: data from an animal model

Posted on by

“Endocannabinoid system seems to be involved in the modulation of NTG-induced hyperalgesia, and probably, in the pathophysiological mechanisms of migraine…

The study confirms that a dysfunction of the endocannabinoid system may contribute to the development of migraine attacks and that a pharmacological modulation of CB receptors can be useful for the treatment of migraine pain…

By combining our data with the findings available from the literature, we can hypothesize that a dysfunction of the endocannabinoid system may contribute to the development of migraine attacks and that a specific pharmacological modulation of CB1 and CB2 receptors may be useful for the treatment of migraine pain, without deleterious effects, as well as of specific associated symptoms (nausea, in primis).”

Cannabinoids and hallucinogens for headache.

Posted on by

“Hallucinogens and most cannabinoids are classified under schedule 1 of the Federal Controlled Substances Act 1970, along with heroin and ecstacy. Hence they cannot be prescribed by physicians, and by implication, have no accepted medical use with a high abuse potential. Despite their legal status, hallucinogens and cannabinoids are used by patients for relief of headache, helped by the growing number of American states that have legalized medical marijuana.

Cannabinoids in particular have a long history of use in the abortive and prophylactic treatment of migraine before prohibition and are still used by patients as a migraine abortive in particular.

 Most practitioners are unaware of the prominence cannabis or “marijuana” once held in medical practice.

Hallucinogens are being increasingly used by cluster headache patients outside of physician recommendation mainly to abort a cluster period and maintain quiescence for which there is considerable anecdotal success.

The legal status of cannabinoids and hallucinogens has for a long time severely inhibited medical research, and there are still no blinded studies on headache subjects, from which we could assess true efficacy.”
