The effects of Cannabis sativa L. seed (hempseed) in the ovariectomized rat model of menopause.

“Cannabis sativa L. has been used for the treatment of various gynecological diseases in traditional medicine.

The potential of this plant to protect against complications of menopause has been raised but rarely studied.

The effects of hempseed on plasma lipid and lipoprotein profiles, estradiol and calcium levels were evaluated.

These results suggest that hempseed may improve post-ovariectomy complications in rats.”

Lipopolysaccharide-induced murine embryonic resorption involves changes in endocannabinoid profiling and alters progesterone secretion and inflammatory response by a CB1-mediated fashion.

“Genital tract infections are a common complication of human pregnancy that can result in miscarriage. We have previously shown that a lipopolysaccharide (LPS) induces embryonic resorption in a murine model of inflammatory miscarriage. This is accompanied by a dramatic decrease in systemic progesterone levels associated with a robust pro-inflammatory response that results in embryo resoprtion.

Here, we tested the hypothesis that the endogenous cannabinoid system (eCS), through cannabinoid receptor 1 (CB1), plays a role in regulating progesterone levels and, therefore, the pro-inflammatory response.

We show that LPS treatment in pregnant mice causes significant changes in the eCS ligands, which are reversed by progesterone treatment. We further show the CB1-KO mice maintain higher plasma progesterone levels after LPS treatment, which is associated with a feebler uterine inflammatory response and a significant drop in embryo resorption.

These data suggest that manipulation of CB1 receptors and/or ligands is a potential therapeutic avenue to decrease infection-induced miscarriage.”

Downstream effects of endocannabinoid on blood cells: implications for health and disease.

“Endocannabinoids (eCBs), among which N-arachidonoylethanolamine (AEA) and 2-arachidonoylglycerol (2-AG) are the most biologically active members, are polyunsaturated lipids able to bind cannabinoid, vanilloid and peroxisome proliferator-activated receptors. Depending on the target engaged, these bioactive mediators can regulate different signalling pathways, at both central and peripheral levels.

The biological action of eCBs is tightly controlled by a plethora of metabolic enzymes which, together with the molecular targets of these substances, form the so-called “endocannabinoid system”.

The ability of eCBs to control manifold peripheral functions has received a great deal of attention, especially in the light of their widespread distribution in the body.

In particular, eCBs are important regulators in blood, where they modulate haematopoiesis, platelet aggregation and apoptosis, as well as chemokine release and migration of immunocompetent cells.

Here, we shall review the current knowledge on the pathophysiological roles of eCBs in blood. We shall also discuss the involvement of eCBs in those disorders affecting the haematological system, including cancer and inflammation.

Knowledge gained to date underlines a fundamental role of the eCB system in blood, thus suggesting that it may represent a therapeutic promise for a broad range of diseases involving impaired hematopoietic cell functions.”

A novel hemp seed meal protein hydrolysate reduces oxidative stress factors in spontaneously hypertensive rats.

Logo of nutrients

“This report shows the antioxidant effects of a hemp seed meal protein hydrolysate (HMH) in spontaneously hypertensive rats (SHR)…

The results suggest that HMH contained antioxidant peptides that reduced the rate of lipid peroxidation in SHRs with enhanced antioxidant enzyme levels and total antioxidant capacity.”

“Cannabis sativa L., also commonly called industrial hemp seed, is historically an important source of food, fibre, dietary oil and medicine; the seed contains about 30% oil and 25% protein…

Proteins from both plant and animal sources, including those of hemp seed, have been isolated and recognized as essential sources of bioactive peptides capable of exerting various in vitro and in vivo activities, such as antioxidant, antihypertensive, antimicrobial, opioid, antithrombotic, hypocholesterolemic, appetite-reducing, mineral-binding, immunomodulatory and cytomodulatory…

HMH may serve as an important ingredient to formulate antioxidant diets with potential therapeutic effects.”

The role of cannabinoids in adult neurogenesis.

“Cannabinoids are a unique class of chemical compounds incorporating plant-derived cannabinoids (the active components of Cannabis sativa), the endogenous cannabinoids and synthetic cannabinoid ligands, and these compounds are becoming increasingly recognized for their roles in neural developmental processes.

Indeed, cannabinoids have clear modulatory roles in adult neurogenesis, likely through activation of both CB1 and CB2receptors.

In recent years a large body of literature has deciphered the signalling networks involved in cannabinoid-mediated regulation of neurogenesis. This timely review summarises the evidence that the cannabinoid system is intricately associated with neuronal differentiation and maturation of NPCs, and highlights intrinsic/extrinsic signalling mechanisms that are cannabinoid targets.

Overall these findings identify the central role of the cannabinoid system in adult neurogenesis in the hippocampus and the lateral ventricles, and hence provide insight into the processes underlying post-developmental neurogenesis in the mammalian brain.”

Smoke Your Troubles Away: Exploring the Effects of Death Cognitions on Cannabis Craving and Consumption.

“When reminded of their death, participants craved cannabis, even though there was no change in their conscious negative mood… Results indicate that cannabis served as a buffer and prevented death-related thoughts from entering consciousness, thus acting as a defense mechanism against death anxiety.”  http://www.ncbi.nlm.nih.gov/pubmed/25950588

New quinolone- and 1,8-naphthyridine-3-carboxamides as selective CB2 receptor agonists with anticancer and immuno-modulatory activity.

“Several recent studies suggest that selective CB2 receptor agonists may represent a valid pharmacological approach in the treatment of various diseases due to the absence of relevant psychoactive side effect…

Two compounds showing the best binding and selectivity profile behaved as a full agonist and a partial agonist at the CB2 receptor and induced a concentration-dependent decrease of cell viability on LNCaP, a prostatic cancer cell line expressing CB2 receptor.

Moreover considering that the CB2 receptor is mainly expressed in cells and organs of the immune system, the same compounds were studied for their potential immune-modulatory and anti-inflammatory effects in activated lymphocytes isolated from healthy controls and multiple sclerosis (MS) patients.”

Cannabis Enhances Bipolar Patients’ Neurocognitive Performance

Image result for medicalnewstoday

“According to a study published online in the journal Psychiatry Research, individuals with bipolar disorder who used cannabis showed higher neurocognitive performance than patients who did not use cannabis.

Researchers at The Zucker Hillside Hospital in Long Island, NY, in collaboration with a team at the Mount Sinai School of Medicine and the Albert Einstein College of Medicine in New York City, examined the difference in cognitive performance among 50 individuals with bipolar disorder who had a history of cannabis use, with 150 bipolar patients who had no history of cannabis use.

The team discovered that patients who used cannabis showed superior neurocognitive performance than those who did not…

“These data could be interpreted to suggest that cannabis use may have a beneficial effect on cognitive functioning in patients with severe psychiatric disorders…””

Cannabinoid Receptor-2 Regulates Embryonic Hematopoietic Stem Cell Development via PGE2 and P-selectin Activity.

“Cannabinoids (CB) modulate adult hematopoietic stem and progenitor cell (HSPCs) function, however, impact on the production, expansion or migration of embryonic HSCs is currently uncharacterized.

Here, using chemical and genetic approaches targeting CB-signaling in zebrafish, we show that CB receptor (CNR) 2, but not CNR1, regulates embryonic HSC development…

Together, these data suggest CNR2-signaling optimizes the production, expansion and migration of embryonic HSCs by modulating multiple downstream signaling pathways.”
