Research Abstract

Accumulated evidence clearly indicates that ER stress is involved in the development of neurodegenerative disorders including Alzheimer's disease. We have investigated the functions of ER stress sensor OASIS, which is specifically expressed in astrocyte. Recently, we established OASIS-/- mouse which shows the increased vulnerability of hippocampal pyramidal neurons to the toxicity of kainic acid. In this study, we found that OASIS expressed in astrocyte plays important roles on the expression and secretion of brain-derived neurotrophic factor (BDNF) to protect the neurons from the toxicity of kainic acid.
