| Outline of Final Research Achievements |
We examined possible roles of neurotransmitter (modulator) candidates contained in the hypothalamic orexin neurons during the defense response against stressors. We performed pharmacological experiment using blockers for the putative cotransmitters and physiological experiment using genetically engineered model mice (orexin knockout mice, orexin neuron-ablated mice, orexin neuron-specific vesicular glutamate transporter-2 knockout mice). We found that glutamate in the orexin neurons play a pivotal role in stress-induced hyperthermia, especially in its early phase, although glutamate was not involved in the basal control of the vigilance state and body temperature. Importance of glutamate in the stress-induced hyperthermia was evident in all the type of stressors so far tested.
