| Outline of Final Research Achievements |
The social behavioral impairment induced by social defeat stress exposure during juveniles was persistent to adult. The development of social impairment may be due to the suppression of neurogenesis via activation of glucocorticoid receptors (GR) induced by stress. The social defeat stress induced dysfunction of serotonergic and dopaminergic neuronal systems in the prefrontal cortex. The combined treatment of a dopamine receptor partial agonist with a selective serotonin reuptake inhibitor or a non-competitive N-methyl-D-aspartate receptor antagonist attenuated the social impairment. DNA microarray analysis revealed that the social defeat stress induced the changes of gene expression in the monoaminegic, glutamatergic neuronal systems, and epigenetic regulation. Juvenile mice are vulnerable to social defeat stress, and activation of GR, monoaminergic and/or glutamatergic neuronal dysfunctions due to changes in related-gene expressions were involved in the social impairment.
