Neuronal Cholesterol Deficiency Mediated by Astrocytic SREBP2 Downregulation Leads to Postoperative Cognitive Dysfunction Through Impairment of Hippocampal Synaptic Plasticity and Excitatory Synaptic Transmission

open access: yesAdvanced Science, EarlyView.
The results showed that the reduction of plasma 24‐hydroxycholesterol (24‐OHC) was related to the cognitive decline in elderly surgical patients. Neuroinflammation induced by anesthesia and surgery significantly downregulated SREBP2 in hippocampal reactive astrocytes, resulting in reduced cholesterol synthesis.
