| Outline of Final Research Achievements |
We had got interested in the Cl- homeodynamics and multimodal GABA actions at genes, cells, and neural network levels. We have investigated, by means of maternal restraint stress GAD67 heterozygous mouse models and taurine transporter (TauT) knock-out (KO) mice, GABA actions on hypothalamic CRH cells in dams as well as neurogenesis, migration, synaptic activities, placental function, HPA axis responses and behavioral responses in pups. We have found multimodal GABA-related molecules responding to GAD67 impairment and restraint stress including their DNA methylation, such as involved in neurogenesis, migration, and synaptic plasticity of GABA neurons and HPA axis activation.
