| Abstract |
The orexinergic system is dysregulated in patients with Alzheimer's disease (AD). In the present study, we evaluated the effects of chronic administration of dual orexin receptor antagonists, suvorexant (Suv) and lemborexant (Lem), on long-term potentiation (LTP) in the hippocampal CA1 region of wild-type (WT) and APPNL-G-F knock-in (APP-KI) mice. LTP was enhanced in APP-KI mice compared with WT mice. Chronic administration of Suv and Lem further potentiated LTP in WT mice. In contrast, in APP-KI mice, Suv moderately and Lem markedly reduced LTP. These findings suggest that orexin receptor antagonists bidirectionally modulate LTP in WT and AD model mice.
