Disruption of Hippocampal Neuregulin 1-ErbB4 Signaling Contributes to the Hippocampus-dependent Cognitive Impairment Induced by Isoflurane in Aged Mice

摘要

BackgroundA prolonged isoflurane exposure may lead to cognitive decline in rodents. Neuregulin 1 (NRG1)-ErbB4 signaling plays a key role in the modulation of hippocampal synaptic plasticity through regulating the neurotransmission. We hypothesized hippocampal NRG1-ErbB4 signaling is involved in isoflurane-induced cognitive impairments in aged mice.
