| Outline of Final Research Achievements |
Autism spectrum disorder (ASD) is a congenital type of the central nervous system such as abnormal synaptogenesis. Relevance to endoplasmic reticulum (ER) stress and ASD is not reported. In this study, I have investigated the effects of ER stress on neuronal differentiation and maturation.
In the brain of ASD model mice, I found the condition of high ER stress and the enhancement of neuronal differentiation. In the culture cells, ER stress led to the enhancement of neuronal differentiation and the inhibition of neurite outgrowth. These events were normalized by the inhibition of ubiquitin ligase HRD1 expression.
The pathogenesis of ASD may be associated with increased HRD1 via high ER stress in the neuronal developmental process.
