A Super Bowl of Cannabinoids

In sports as in life, teamwork creates homeostasis. Sure there will be big plays and impressive moves in Sunday’s Super Bowl, yet all fans and players know it’s the little things that count – that create the conditions for that game-winning moment. It’s the same in our bodies as homeostatic processes – teamwork – function without notice or acclaim (even while we sleep). In celebration of game-winning moments, here are four new PubMed articles discussing our CS and homeostatic teamwork: management of neuroinflammatory (brain) disorders, CB1 anti-aversive panic properties, obesity and the therapeutic agents THCV and CBD, and cannabinoids as a tool in modern cancer pharmacotherapy.

Happy CS Super Bowl All!

I. Neuroinflammatory: Cannabinoids as Immunoregulatory and Immunomodulatory
“A growing body of evidence suggests that Cannabis sativa-derived phytocannabinoids, as well as synthetic cannabinoids, are endowed with significant immunoregulatory and anti-inflammatory properties, both in peripheral tissues and in the CNS, through the activation of cannabinoid receptors. In this review, the immunomodulatory effects of cannabinoid signaling on the most relevant brain immune cells will be discussed. In addition, the impact of cannabinoid regulation on the overall integration of the manifold brain immune responses will also be highlighted, along with the implication of these compounds as potential agents for the management of neuroinflammatory disorders.”

II. Brain: Panic, Dorsolateral Periaqueductal Grey and CS CB1 Receptors
“Since the cannabinoid CB1 receptor modulates various types of aversive responses, this study tested the hypothesis that enhancement of endocannabinoid signalling in the dorsolateral periaqueductal grey inhibits panic-like reactions in rats. … The present results confirm the anti-aversive property of direct CB1 receptor activation in the dorsolateral periaqueductal grey.”

III. Obesity: Liver Metabolism, Hepatosteatosis and the Cannabinoids THCV and CBD
“Obesity and associated metabolic syndrome have quickly become a pandemic and a major detriment to human health globally. The presence of non-alcoholic fatty liver disease (NAFLD; hepatosteatosis) in obesity has been linked to the worsening of the metabolic syndrome, including the development of insulin resistance and cardiovascular disease. Currently, there are few options to treat NAFLD, including life style changes and insulin sensitizers. Recent evidence suggests that the cannabinoids Δ9-tetrahydrocannabivarin (THCV) and cannabidiol (CBD) improve insulin sensitivity; we aimed at studying their effects on lipid levels. … Our results suggest that THCV and CBD might be used as new therapeutic agents for the pharmacological treatment of obesity- and metabolic syndrome-related NAFLD/hepatosteatosis.”

PMID: 25595882 [PubMed - as supplied by publisher]

IV. Cancer: Cannabinoids and Antimetastatic and Antiangiogenesis
“Regarding the underlying antimetastatic mechanism, several studies revealed cannabinoids to alter the gene expression of cancer cells toward a less-aggressive phenotype and to modulate their secretomic profile. Cannabinoids likewise modulate the release of factors from tumor cells that subsequently suppress the chemoattraction of vessel cells thereby conferring antiangiogenesis. … In addition, beneficial interactions of cannabinoids with currently used chemotherapeutics as well as the influence of cannabinoids on tumor-immune surveillance are addressed. Collectively, the currently available data suggest cannabinoids as a potential tool in modern cancer pharmacotherapy.”

Namaste Bryan William Brickner.

Homeostatic processes and teamwork with best wishes.

The NFL is the preeminent sports league in the U.S. but it is woefully behind the curve when it comes to marijuana and players are suffering as a result. Many former and current NFL players use or have used marijuana to treat pain associated with injuries sustained on the field. There is a compelling body of research showing that marijuana can help treat pain and brain injuries. (1)

2014 - Effect of marijuana use on outcomes in traumatic brain injury.

Traumatic brain injury (TBI) is associated with significant morbidity and mortality. Several studies have demonstrated neuroprotective effects of cannabinoids. The objective of this study was to establish a relationship between the presence of a positive toxicology screen for tetrahydrocannabinol (THC) and mortality after TBI.

A 3-year retrospective review of registry data at a Level I center of patients sustaining TBI having a toxicology screen was performed. Pediatric patients (younger than 15 years) and patients with a suspected nonsurvivable injury were excluded. The THC(+) group was compared with the THC(-) group with respect to injury mechanism, severity, disposition, and mortality. Logistic regression was used to determine independent associations with mortality. There were 446 cases meeting all inclusion criteria.

The incidence of a positive THC screen was 18.4 per cent (82). Overall mortality was 9.9 per cent (44); however, mortality in the THC(+) group (2.4% [two]) was significantly decreased compared with the THC(-) group (11.5% [42]; P = 0.012).

After adjusting for differences between the study cohorts on logistic regression, a THC(+) screen was independently associated with survival after TBI (odds ratio, 0.224; 95% confidence interval, 0.051 to 0.991; P = 0.049).

A positive THC screen is associated with decreased mortality in adult patients sustaining TBI.
