Schizophrenia is a complex disease with uncertain aetiology. We suggest GABBR1, GABA receptor B1 implicated in schizophrenia based on a HERV-W LTR in the regulatory region of GABBR1. Our hypothesis is supported by: (i) GABBR1 is in the 6p22 genomic region most often implicated in schizophrenia; (ii) microarray studies found that only presynaptic pathway-related genes, including GABA receptors, have altered expression in schizophrenic patients and (iii) it explains how HERV-W elements, expressed in schizophrenia, play a role in the disease: by altering the expression of GABBR1 via a long terminal repeat that is also a regulatory element to GABBR1.

OBJECTIVES: Borna disease virus (BDV) is an RNA virus belonging to the family Bornaviridae. BDV is a neurotropic virus that causes changes in mood, behaviour and cognition. Patients with psychiatric disorders have a higher incidence of BDV positivity than healthy individuals. METHODS: We examined the seropositivity of BDV circulating immunocomplexes (CIC) in psychiatric patients and healthy individuals (blood donors). We examined 39 psychiatric inpatients for the presence of BDV CIC in the serum by ELISA on day 0, 28 and 56. During the same period psychopathology was measured using psychiatric scales (CGI, CGI-I, MADRS, SDS, PANSS). This is the first such study performed in the Czech Republic. RESULTS: BDV CIC positivity was detected in 66.7% of psychiatric patients (26/39) on day 0, in 53.9% (14/26) on day 28 and in 52.9% on day 56 (9/17). The control group was 22.2% (28/126) positive. The incidence of BDV CIC was significantly higher in psychiatric patients than in healthy individuals (p=0.001). The significantly higher level of BDV CIC was associated with the higher severity of psychopathology in comparison with patients with mild or moderate psychopathology (p=0.03). We did not find any association between BDV CIC positivity and other characteristics (age, diagnosis, family, personal history, the history of infectious diseases, contact with animals). CONCLUSION: In our study psychiatric patients had significantly higher levels of BDV CIC than the control group. The highest levels of BDV CIC were detected in patients with more severe psychopathology.
