Endocannabinoid hydrolysis inhibition unmasks that unsaturated fatty acids induce a robust synthesis of 2-arachidonoyl-glycerol and its congeners in human myeloid leukocytes

2020: In mice with mucositis (oral lesions, often from chemotherapy), CBD protected the mouth via anti-inflammatory and antioxidant activity as well as speeding repair

Cannabidiol on 5-FU-induced Oral Mucositis in Mice

2020: In mice, activation of CB1 increased secretion of IL-10 while reducing inflammation and organ injury

Activation of CB1R Promotes Lipopolysaccharide-Induced IL-10 Secretion by Monocytic Myeloid-Derived Suppressive Cells and Reduces Acute Inflammation and Organ Injury

2020: In human monocytes (a type of white blood cell), the anti-inflammation effects of CBD are mediated by modulation of the P2X7 inflammasome receptor

Inhibitory Effect of Cannabidiol on the Activation of NLRP3 Inflammasome Is Associated with Its Modulation of the P2X7 Receptor in Human Monocytes

2020: In mice, swimming exercise reduced inflammatory pain via the ECS

High-intensity swimming exercise reduces inflammatory pain in mice by activation of the endocannabinoid system

2020: In macrophages (mobile white blood cell), the Toll-like receptors (TLRs) sense pathogens & then pass on their message via the myeloid differentiation factor 88 (MyD88) adaptor. Both CBD & THC modulate the MyD88 signaling to help with inflammation

MyD88-dependent and -independent signalling via TLR3 and TLR4 are differentially modulated by Δ9-tetrahydrocannabinol and cannabidiol in human macrophages

2020: In mice, CB1 receptors control pain via pathways in the thalamus

Incerta-thalamic Circuit Controls Nocifensive Behavior via Cannabinoid Type 1 Receptors

2020: In a rare study of gender differences, this mouse study showed that the pain-relieving effects of the cannabinoids was greater in males than females

Evaluation of the Preclinical Analgesic Efficacy of Naturally Derived, Orally Administered Oil Forms of Δ9-tetrahydrocannabinol (THC), Cannabidiol (CBD), and Their 1:1 Combination

2020: In rats, the CB1 receptors are involved in pain signals processed by the ventrolateral periaqueductal gray matter (the brain region known as the primary control center for descending pain modulation) & blocking the CB1 receptors before a painful stimulus increased the learning & memory impairments

Blockage of ventrolateral periaqueductal gray matter cannabinoid 1 receptor increases dental pulp pain and pain-related subsequent learning and memory deficits in rats

2019: in tissue culture, CBD extracts & isolated CBD both inhibited inflammatory leukocytes – both effect cell migration and TNF-α production but the extract is more potent - but isolated CBD better for lowering reactive oxygen species production

A Novel Standardized Cannabis sativa L. Extract and Its Constituent Cannabidiol Inhibit Human Polymorphonuclear Leukocyte Functions

2019: CB2 receptors in the spinal cord may be involved in pain-reducing effects of exercise

Involvement of Spinal Cannabinoid CB2 Receptors in Exercise-Induced Antinociception

2018: In rats, CBDA & THC both lowered pain & inflammation

Effect of cannabidiolic acid and ∆9-tetrahydrocannabinol on carrageenan-induced hyperalgesia and edema in a rodent model of inflammatory pain
