The relative content of peripheral benzodiazepine receptor (pBR) mRNA was examined by reverse transcriptase-polymerase chain reaction in lymphocytes of obsessive-compulsive disorder (OCD) patients, according to their clinical course of illness. pBR mRNA significantly decreased only in chronic OCD patients (n=8) as compared to controls (n=10), whereas no significant changes were observed in episodic OCD patients (n=7). We suggest that modulation of pBR gene expression might delineate a clinical heterogeneity in OCD.
