5 +/- 1.6 years). The blood titers of PAA were evaluated using an optimized ELISA test, expressed by a linear optical density (OD) scale. The blood samples of all participants were tested anonymously and were scored under a code number. A test recording above 1.4 OD units was predefined as positive. Results: The titers of PAA of children with schizophrenia (1.9 +/- 0.5 OD units, range: 0.7-2.44 units) were significantly selleck chemicals llc (p < 0.00001) higher than

those of the control group (1.0 +/- 0.4 OD units, range: 0.45-2.28 units). In 83% of the children with schizophrenia (24 out of the 29 patients) a positive test, i.e. OD >1.4, was detected. In contrast, in the control group, only 12% (3 of the 25 subjects) displayed a positive test, p < 0.00001. Conclusions: High titers of PAA in children with schizophrenia as compared with nonpsychotic controls may indicate an active autoimmune process in the early onset of schizophrenia. The PAA level may therefore provide a supportive diagnostic biomarker for childhood schizophrenia. Copyright (C) 2013 S. Karger AG, Basel”
“Prepulse inhibition (PPI) of startle is a measure of sensorimotor gating that is heritable and

JSH-23 concentration deficient in certain psychiatric disorders, including schizophrenia. Sprague-Dawley (SD) rats are more sensitive to PPI disruptive effects of dopamine (DA) agonists at long interstimulus intervals (60-120 ms) and less sensitive to their PPI-enhancing effects at short (10-30 ms), compared with Long-Evans (LE) rats. These heritable strain differences in sensitivity to the PPI disruptive effects of DA agonists must ultimately reflect neural changes “”downstream”" from forebrain DA receptors.

The current study evaluated the effects of the DA agonist, apomorphine (APO), on ventral pallidal (VP) gamma-aminobutyric acid (GABA) and glutamate efflux

and PPI in SD and LE rats.

PPI was tested in SD and LE rats after vehicle or APO (0.5 mg/kg, subcutaneously (s.c.)) in a within-subject design. In different SD and GNAT2 LE rats, VP dialysate was collected every 10 min for 120 min after vehicle or APO (0.5 mg/kg, s.c.) and analyzed for GABA and glutamate content by capillary electrophoresis (CE) coupled with laser-induced fluorescence (LIF).

As predicted, SD rats exhibited greater APO-induced PPI deficits at long intervals and less APO-induced PPI enhancement at short intervals compared to LE rats. APO significantly reduced VP GABA efflux in SD but not in LE rats; glutamate efflux was unaffected in both strains.

Heritable strain differences in PPI APO sensitivity in SD vs LE rats parallel, and may be mediated by, strain differences in the VP GABA efflux.”
