The protective effects of β-caryophyllene on LPS-induced primary microglia M1/M2 imbalance: A mechanistic evaluation.

Life Sciences

“Neuroinflammation is observed as a routine characterization of neurodegenerative disorders such as dementia, multiple sclerosis (MS) and Alzheimer’s diseases (AD). Scientific evidence propounds both of the neuromodulatory and immunomodulatory effects of CB2 in the immune system. β-Caryophyllene (BCP) is a dietary selective CB2 agonist, which deserves the anti-inflammatory and antioxidant effects at both low and high doses through activation of the CB2 receptor.

METHODS:

In this study, we investigated the protective effects of a broad range concentration of BCP against LPS-induced primary microglia cells inflammation and M1/M2 imbalance and identifying the portion of the involvement of related signaling pathways on BCP effects using pharmacological antagonists of CB2, PPAR-γ, and sphingomyelinase (SMase).

KEY FINDINGS:

The protective effects of BCP on LPS-induced microglia imbalance is provided by the M2 healing phenotype of microglia, releasing the anti-inflammatory (IL-10, Arg-1, and urea) and anti-oxidant (GSH) parameters and reducing the inflammatory (IL-1β, TNF-α, PGE2, iNOS and NO) and oxidative (ROS) biomarkers. Moreover, we showed that BCP exerts its effects through CB2receptors which overproduction of ceramides by SMase at middle to higher concentrations of BCP reduce the protective activity of BCP and results in the activation of the PPAR-γ pathway.

SIGNIFICANCE:

In conclusion, the low concentration of BCP has higher selective anti-inflammatory effects rather than high levels. On this occasion, BCP by modulating the microglia is able to have potential therapeutic effects in neuro-inflammation conditions and microglia cells such as MS and AD.”

Production, digestibility and allergenicity of hemp (Cannabis sativa L.) protein isolates.

Food Research International

“Hemp (Cannabis sativa L.), traditionally cultivated for industrial use and harvested for fibers and seeds, has raised much interest as a sustainable crop in the last years.

Recently, hemp seeds and derived oil have started to be used in a variety of food products. Hemp-based food products are considered less allergenic than those from other edible seeds, although this statement has never been experimentally verified.

In this study high purity grade hemp flour (HF) and hemp protein isolate (HPI) were obtained through a fast and cheap process starting from defatted hemp cakes, a residue of hempseed oil extraction.

HPI resulted enriched at nearly 86% protein, mainly constituted by the storage protein edestin (accounting for 70% total protein). In vitro protein digestibility was determined using a static model of gastrointestinal digestion (GID), which included a final step with purified brush border membrane (BBM) enzyme preparations. HF and HPI showed a high degree of digestibility. The survival of potential bioactive and/or allergenic peptide sequences in digests was investigated by peptidomic analysis. Only a limited number of sequences survived GID. Among them, fragments from 12 seed proteins. These fragments were precursors of sequences with potential bioactive peptides, which might justify the bioactivity of HPI hydrolysates, reported in previous studies.

More importantly, all known hemp allergens, including the major thaumatin-like protein and LTP, were entirely eliminated by the HPI production process, neither fragments of the proteins were present after GID.

These data support the use of HPI as an ingredient for hypoallergenic foods.”

Nutraceutical potential of hemp (Cannabis sativa L.) seeds and sprouts.

 Food Chemistry “In this study the antioxidant effect of Cannabis sativa L. seeds and sprouts (3 and 5 days of germination) was evaluated. Total polyphenols, flavonoids and flavonols content, when expressed on dry weight basis, were highest in sprouts; ORAC and DPPH (in vitro assays), CAA-RBC (cellular antioxidant activity in red blood cells) and hemolysis test (ex vivo assays) evidenced a good antioxidant activity higher in sprouts than in seeds. Untargeted analysis by high resolution mass spectrometry in negative ion mode allowed the identification of main polyphenols (caffeoyltyramine, cannabisin A, B, C) in seeds and of ω-6 (linoleic acid) in sprouts. Antimutagenic effect of seeds and sprouts extracts evidenced a significant decrease of mutagenesis induced by hydrogen peroxide in Saccharomyces cerevisiae D7 strain. In conclusion our results show that C. sativa seeds and sprouts exert beneficial effects on yeast and human cells and should be further investigated as a potential functional food.” https://www.ncbi.nlm.nih.gov/pubmed/29751921 https://www.sciencedirect.com/science/article/pii/S0308814618307180?via%3Dihub
