GPR3 is an orphan receptor which has been associated with Alzheimer's disease. CBD acts as inverse agonist of GPR3, suggesting therapeutic potential to treat Alzheimer's disease.

Literature Discussion

GPR3 and GPR6 have been previously linked to Alzheimer's and Parkinson's diseases. These receptors share about 35% of amino acid sequence with CB1 and CB2. CBD acts as an inverse agonist for these receptors as it has been shown in a β-arrestin2 recruitment assay (Laun & Song, 2017).
