Research Roundup: May 24, 2021

Best of the Week...

This survey of patients with fibromyalgia found that the majority used CBD products to discontinue their use of NSAIDs, opioids, gabapentanoids & benzos. They saw improvements in health, pain, memory & sleep

Substituting Cannabidiol for Opioids and Pain Medications Among Individuals with Fibromyalgia: a Large Online Survey In humans, this cohort analysis found that the diversity of your gut microbiome was related to your happiness & motivation via the endocannabinoid system, especially via PEA - which they call the endogenous version of CBD Endocannabinoid system mediates the association between gut-microbial diversity and anhedonia/amotivation in a general population cohort

In the brain immune cells of mice, CBD causes anti-inflammatory & neuroprotective effects

Studies of involvement of G-protein coupled receptor-3 in cannabidiol effects on inflammatory responses of mouse primary astrocytes and microglia

In intestinal cells, CBD was their most promising compound against inflammation & oxidative stress

In a mouse model of ALS, inactivating the CB2 receptor worsened the disease progression

Inactivation of the CB 2 receptor accelerated the neuropathological deterioration in TDP-43 transgenic mice, a model of amyotrophic lateral sclerosis

In brain slices from rats, persistent inflammation lowers the number of CB1 receptors in the rostral ventromedial medulla (a brain region related to pain signaling)
