According to recent research from Austria, it "has been proposed that neurotransmitter receptor expression in peripheral immune cells reflects expression of these receptors in the brain." "To test this 'peripheral marker hypothesis'," C. Czermak and coauthors at the University of Graz "compared mRNA expression of the dopamine receptors D3 (DRD3) and D4 (DRD4) in peripheral blood lymphocytes (PBL) to personality traits assessed with the Temperament and Character Inventory (TCI) in 50 healthy and unmedicated Caucasian individuals."
