Cannabinoid CB1 receptors and mTORC1 signalling pathway interact to modulate glucose homeostasis.

Posted on by

“The endocannabinoid system (ECS) is an inter-cellular signalling mechanism that is present in the islets of Langerhans and plays a role in the modulation of insulin secretion and beta-cell mass expansion.

The mammalian target of rapamycin complex 1 (mTORC1) is a key intra-cellular pathway involved in energy homeostasis and known to importantly affect pancreatic islet’s physiology.

These findings suggest a functional interaction between the ECS and the mTORC1 pathway within the endocrine pancreas and at the whole organism level, which could have implications for the development of new therapeutic approaches for pancreatic beta-cell diseases.”

Cannabinoids for nausea and vomiting in adults with cancer receiving chemotherapy.

Posted on by

“Cannabis has a long history of medicinal use.

Cannabis-based medications (cannabinoids) are based on its active element, delta-9-tetrahydrocannabinol (THC), and have been approved for medical purposes.

Cannabinoids may be a useful therapeutic option for people with chemotherapy-induced nausea and vomiting that respond poorly to commonly used anti-emetic agents (anti-sickness drugs).

Cannabis-based medications may be useful for treating refractory chemotherapy-induced nausea and vomiting.”

Metabolic Syndrome among Marijuana Users in the United States: An Analysis of National Health and Nutrition Examination Survey Data.

Posted on by

“Research on the health effects of marijuana use in light of its increased medical use and the current obesity epidemic is needed. Our objective was to explore the relationship between marijuana use and metabolic syndrome across stages of adulthood…

Current marijuana users had lower odds of presenting with metabolic syndrome than never users. Among emerging adults, current marijuana users were 54% less likely than never users to present with metabolic syndrome. Current and past middle-aged adult marijuana users were less likely to have metabolic syndrome than never users.

CONCLUSIONS:

Current marijuana use is associated with lower odds of metabolic syndrome across emerging and middle-aged US adults.”

Endocannabinoid regulation of nausea is mediated by 2-arachidonoylglycerol (2-AG) in the rat visceral insular cortex.

Posted on by

“Cannabinoid (CB) agonists suppress nausea in humans and animal models; yet, their underlying neural substrates remain largely unknown.

Evidence suggests that the visceral insular cortex (VIC) plays a critical role in nausea. Given the expression of CB1 receptors and the presence of endocannabinoids in this brain region, we hypothesized that the VIC endocannabinoid system regulates nausea…

Taken together, these findings provide compelling evidence that acute nausea selectively increases 2-AG in the VIC, and suggests that 2-AG signaling within the VIC regulates nausea by reducing neuronal activity in this forebrain region.”

Clinical Significance of Cannabinoid Receptors CB1 and CB2 Expression in Human Malignant and Benign Thyroid Lesions.

Posted on by

“The endocannabinoid system is comprised of cannabinoid receptors (CB1 and CB2), their endogenous ligands (endocannabinoids), and proteins responsible for their metabolism participate in many different functions indispensable to homeostatic regulation in several tissues, exerting also antitumorigenic effects.

The present study aimed to evaluate the clinical significance of CB1 and CB2 expression in human benign and malignant thyroid lesions.

Our data suggest that CB receptors may be involved in malignant thyroid transformation and especially CB2 receptor could serve as useful biomarker and potential therapeutic target in thyroid neoplasia.”

[There is evidence for the use of cannabinoids for symptomatic treatment of multiple sclerosis].

Posted on by

“We identified 16 randomized placebo-controlled trials investigating cannabinoids as symptomatic treatment in multiple sclerosis (MS). There is evidence that nabiximols oromucosal spray may reduce subjective symptoms of spasticity and that dronabinol is effective against neuropathic pain in patients with MS.”

Activation of Endocannabinoid System Is Associated with Persistent Inflammation in Human Aortic Aneurysm.

Posted on by

“Human aortic aneurysms have been associated with inflammation and vascular remodeling. Since the endocannabinoid system modulates inflammation and tissue remodeling, we investigated its components in human aortic aneurysms…

Our data provides evidence for endocannabinoid system activation in human aortic aneurysms, associated with persistent low-level inflammation and vascular remodeling.”

Transdermal cannabidiol reduces inflammation and pain-related behaviours in a rat model of arthritis.

Posted on by

“Current arthritis treatments often have side-effects attributable to active compounds as well as route of administration.

Cannabidiol(CBD) attenuates inflammation and pain without side-effects…

These data indicate that topical CBD application has therapeutic potential for relief of arthritis pain-related behaviours and inflammation without evident side-effects.”

Crosstalk between endocannabinoid and immune systems: a potential dysregulation in depression?

Posted on by

“The endocannabinoid (eCB) system, an endogenous lipid signaling system, appears to be dysregulated in depression. The role of endocannabinoids (eCBs) as potent immunomodulators, together with the accumulating support for a chronic low-grade inflammatory profile in depression, suggests a compelling hypothesis for a fundamental impairment in their intercommunication, in depression.

OBJECTIVE:

We aim to review previous literature on individual associations between the immune and eCB systems and depression. It will focus on peripheral and central mechanisms of crosstalk between the eCB and immune systems. A potential dysregulation in this crosstalk will be discussed in the context of depression.

RESULTS:

Investigations largely report a hypoactivity of the eCB system and increased inflammatory markers in individuals with depression. Findings depict a multifaceted communication whereby immunocompetent and eCB-related cells can both influence the suppression and enhancement of the other’s activity in both the periphery and central nervous system. A dysregulation of the eCB system, as seen in depression, appears to be associated with central and peripheral concentrations of inflammatory agents implicated in the pathophysiology of this illness.

CONCLUSION:

The eCB and immune systems have been individually associated with and implicated in pathogenic mechanisms of depression. Both systems tightly regulate the other’s activity. As such, a dysregulation in this crosstalk has potential to influence the onset and maintenance of this neuropsychiatric illness. However, few studies have investigated both systems and depression conjointly. This review highlights the demand to consider joint eCB-immune interactions in the pathoetiology of depression.”

The prescription of medical cannabis by a transitional pain service to wean a patient with complex pain from opioid use following liver transplantation: a case report.

Posted on by

Canadian Journal of Anesthesia/Journal canadien d'anesthésie

“The purpose of this case report is to describe a patient with a preoperative complex pain syndrome who underwent liver transplantation and was able to reduce his opioid consumption significantly following the initiation of treatment with medical cannabis.

CLINICAL FEATURES:

A 57-yr-old male with a history of hepatitis C cirrhosis underwent liver transplantation. Preoperatively, he was taking hydromorphone 2-8 mg⋅day-1 for chronic abdominal pain. Postoperatively, he was given intravenous patient-controlled analgesia through which he received hydromorphone 30 mg⋅day-1. Our multidisciplinary Transitional Pain Service was involved with managing his moderate to severe acute postsurgical pain in hospital and continued with weaning him from opioid medications after discharge. It was difficult to wean the patient from opioids, and he was subsequently given medical cannabis at six weeks postoperatively with remarkable effect. By the fifth postoperative month, his use of opioids had tapered to 6 mg⋅day-1 of hydromorphone, and his functional status was excellent on this regimen.

CONCLUSION:

Reductions in opioid consumption were achieved with the administration of medical cannabis in a patient with acute postoperative pain superimposed on a chronic pain syndrome and receiving high doses of opioids. Concurrent benefits of initiating medical cannabis may include improvements in pain profile and functional status along with reductions in opioid-related side effects. This highlights the potential for medical cannabis as an adjunct medication for weaning patients from opioid use.”
