Endoplasmic reticulum stress mediates distinct impacts of sevoflurane on different subfields of immature hippocampus.
Sevoflurane, a typical inhaled anesthetic, is widely used in patients of all ages during surgery. The negative effects, such as inducing cell death and damaging spatial memory, of sevoflurane on neurodevelopment have raised increasing concerns in recent years. However, the molecular mechanism remains unclear. ⋯ Meanwhile, CA1 pyramidal neurons exhibited significantly reduced intrinsic excitability. Furthermore, the administration of ER stress inhibitor attenuated the above mentioned detrimental effects evidently and prevented the following relevant learning and memory deficits. In conclusion, sevoflurane-mediated ER stress performs distinct effects on the different subfields of the immature hippocampus and inhibiting ER stress during sevoflurane anesthesia will be a potential method to prevent the following learning and memory deficits in adulthood.
