The effects of hempseed meal intake and linoleic acid on Drosophila models of neurodegenerative diseases and hypercholesterolemia

Molecules and Cells

“Hemp seed is rich in polyunsaturated fatty acids (PUFAs), which have potential as therapeutic compounds for the treatment of neurodegenerative and cardiovascular disease.

In this study, we assessed the effects of the intake of  hempseed meal (HSM) and PUFAs on oxidative stress, cytotoxicity and neurological phenotypes, and cholesterol uptake, using Drosophila models.

HSM intake was shown to reduce H(2)O(2) toxicity markedly, indicating that HSM exerts a profound antioxidant effect.

Meanwhile, intake of HSM, as well as linoleic or linolenic acids (major PUFA components of HSM) was shown to ameliorate Aβ42-induced eye degeneration, thus suggesting that these compounds exert a protective effect against Aβ42 cytotoxicity.

Additionally, intake of HSM or linoleic acid was shown to reduce cholesterol uptake significantly.

Moreover, linoleic acid intake has been shown to delay pupariation, and cholesterol feeding rescued the linoleic acid-induced larval growth delay, thereby indicating that linoleic acid acts antagonistically with cholesterol during larval growth.

In conclusion, our results indicate that HSM and linoleic acid exert inhibitory effects on both Aβ42 cytotoxicity and cholesterol uptake, and are potential candidates for the treatment of Alzheimer’s disease and cardiovascular disease.”

“A number of previous studies have shown that polyunsaturated fatty acids (PUFAs) and phytosterols are critically important for human health. Hempseed is a rich source of plant oil, which contains more than 80% PUFAs and 3922-6719 mg/kg of phytosterols (e.g., sitosterol and campesterol). The fatty acids in hempseed oil include a variety of essential fatty acids, including linoleic acid ”

Alzheimer’s disease; taking the edge off with cannabinoids?

“Thus, cannabinoids offer a multi-faceted approach for the treatment of Alzheimer’s disease by providing neuroprotection and reducing neuroinflammation, whilst simultaneously supporting the brain’s intrinsic repair mechanisms by augmenting neurotrophin expression and enhancing neurogenesis. The evidence supporting a potential role for the cannabinoid system as a therapeutic target for the treatment of Alzheimer’s disease will be reviewed herewith.”

Cannabidiol and other cannabinoids reduce microglial activation in vitro and in vivo: relevance to Alzheimer’s disease

“CBD is able to modulate microglial cell function in vitro and induce beneficial effects in an in vivo model of AD. Given that CBD lacks psychoactivity, it may represent a novel therapeutic approach for this neurological disease.”

Cannabidiol: from an inactive cannabinoid to a drug with wide spectrum of action

“These studies have suggested a wide range of possible therapeutic effects of cannabidiol on several conditions, including Parkinson’s disease, Alzheimer’s disease, cerebral ischemia, diabetes, rheumatoid arthritis, other inflammatory diseases, nausea and cancer.”

Neuroprotective effect of cannabidiol, a non-psychoactive component from Cannabis sativa, on beta-amyloid-induced toxicity in PC12 cells

“Our results indicate that cannabidiol exerts a combination of neuroprotective, anti-oxidative and anti-apoptotic effects against beta-amyloid peptide toxicity, and that inhibition of caspase 3 appearance from its inactive precursor, pro-caspase 3, by cannabidiol is involved in the signalling pathway for this neuroprotection.”

Marijuana Slows Alzheimer’s Decline

“the investigators confirmed that cannabinoids counteracted the activation of microglia and thus reduced inflammation.  These findings that cannabinoids work both to prevent inflammation and to protect the brain may set the stage for their use as a therapeutic approach for Alzheimer’s disease, de Ceballos said.”
