Abstract
This study sought to determine whether cannabinoid-1 (CB1) receptor binding was altered in the postmortem dorsolateral prefrontal cortex (DLPFC) of individuals with schizophrenia (schizophrenia; n = 47) compared to controls (n = 43). The CB1 receptor inverse agonist radioligand [H-3]MePPEP was used to measure specific binding to CB1 receptors. The specific binding of [H-3]MePPEP to CB1 receptors was 20% higher in patients with schizophrenia than in controls. Power analyses suggested that 53 subjects per group would be needed to detect a similar difference in vivo with positron emission tomography (PET) and the structurally related inverse agonist radioligand [F-18]FMPEP-d(2) (80% statistical power, p<0.05).
