| Outline of Final Research Achievements |
Background: The mechanisms by which inhalational anesthetics cause neurotoxicity are not well clarified. Since ER stress leads to cellular dysfunction and apoptotic cell death, leading to diverse human disorders such as neurodegenerative diseases, we hypothesized ER stress may play a role in neurotoxicity caused by inhalational anesthetics.
Results,Conclusions: Sevoflurane exposure cause ER stress, which is tolerated to some extent in the wild type cells. When this tolerance is limited, like in cells with mutant BiP, the exposure leads to cell death in the brain, indicating that ER stress may partially mediate neurotoxicity caused by inhalational anesthetics. This study conceivable that the patients with certain conditions sensitive to ER stress such as ischemia, hypoxia, developing brain or neurodegenerative diseases may be vulnerable to inhalational anesthetics.
