Research Abstract |
1.An animal model for schizophrenia based on hypothesis of neural stem cell dysfunction : (1)Male Sprague-Dawley rats were irradiated to the forebrain using 6 fractions of 5 Gy. After 12 weeks, neural stem cells (BrdU positive cells) were diminished in both subventricular zone and hippocampal dentate gyrus subgranular zone. A significant increase in locomotor activity after administration of methamphetamine (MAP) (2 mg/kg i.p.) or MK-801 (0.2 mg/kg i.p.) was observed. Acoustic prepulse inhibition and social behaviors of the irradiated rats were significantly decreased. Moderate impairments of spatial working memory and reference memory assessed by Morris water maze were found in the model rats. (2)It has been reported that LIFR-deficient mice revealed a reduction in the number of adult neural stem cells. Locomotor activity induced by MAP was significantly increased in the LIFR knockout mice. However, behavioral change after MK-801 or prepulse inhibition of startle responces was not obse

rved. (3)We transplanted embryonic neural precursor cells (NPCs) into the bilateral ventricles and the dentate gyri of the irradiated rats at 3 months after irradiation. The MAP-induce hyperactivity was not ameliorated at 4 weeks after the NPCs transplantation. 2.Peripheral biological markers for schizophrenia : Reelin is a secretory protease with major roles in neurodevelopment and plasticity. A reduction of reelin expression is one of the most robust molecular findings in schizophrenia. Apolipoprotein E receptor 2 (ApoER2) and very-low-density lipoprotein receptor (VLDLR) are reelin receptors. In search for peripheral biological markers for schizophrenia we have investigated mRNA levels of ApoER2 and VLDLR in peripheral blood lymphocytes of drug naive patients with schizophrenia, mood disorder and healthy controls. We observed a significant decrease of VLDLR mRNA levels in schizophrenia, but not those in mood disorder, compared with controls. A significant decrease in the ApoER2 mRNA level was found only in mood disorder. Less
