关键词: chronic sleep deprivation cognitive impairment Farnesol oxidative stress Sirt1/Nrf2 signaling pathway

摘要:
Sleep deprivation (SD) negatively affects all aspects of health, with one serious consequence being impaired cognition. Farnesol (FOL) is a sesquiterpene synthesized by plants and mammals that has antioxidant, anti-inflammatory, and neuroprotective properties. This study investigates the mechanism underlying the neuroprotective effect of FOL on SD-induced cognitive impairment.Administration of FOL dramatically ameliorates chronic sleep deprivation (CSD)-induced cognitive impairment. In addition, FOL notably attenuates oxidative stress damage, pro-inflammatory cytokines activation, and microglial activation in the hippocampi of the CSD-exposed mice. Further examination indicates that administration of FOL after the CSD significantly increases the protein expressions of silent information regulator factor 2-related enzyme 1 (Sirt1), nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), and glutathione peroxidase 4 (Gpx4) in the hippocampi. Sirt1 agonist resveratrol (RES) has a similar neuroprotective effect, indicating that FOL could exert neuroprotective effects through the activation of the Sirt1/Nrf2 signaling pathway.The results reveal that FOL could protect against CSD-induced cognitive impairment by activating the Sirt1/Nrf2 signaling pathway.© 2023 Wiley-VCH GmbH.
