Letter by Wu et al Regarding Article, “G Protein-Coupled Receptor Kinase 3 Exacerbates Diabetic Heart Injuries Through Direct Phosphorylation of Cannabinoid Receptor 2 in Humans and Mice”.

Laboratory research published in Circulation identifies how diabetes may worsen heart complications through disruption of cannabinoid receptor 2 function. This diabetic heart disease cannabinoid receptor research provides mechanistic insights but requires clinical validation before therapeutic applications.

A sesquiterpene-rich essential oil from Cannabis sativa L. attenuates symptoms and neuroinflammation in experimental autoimmune encephalomyelitis model through a CB2-mediated signalling.

Researchers found that cannabis essential oil neuroinflammation reduction occurred through CB2 receptor activation in an experimental multiple sclerosis model. The sesquiterpene-rich formulation improved pain, motor function, and emotional symptoms without psychoactive effects. While promising, this preclinical evidence requires human validation before clinical application.
