Speech Title: The anti-Alzheimer’s disease effects of natural compounds and the mechanism related to ferroptosis
Abstract: During the pathological process of Alzheimer’s disease (AD), ferroptosis gradually emerges, becoming a study target for AD treatment. Besides ferroptosis, brain tissue is particularly vulnerable to neuroinflammation, which can aggravate Aβ deposition and tau phosphorylation. GV-971, a drug that reduces peripheral and central inflammation, was approved by the FDA in April 2020 for an international multi-center phase III clinical trial IND (IND 144482), which provides a strong basis for neuroinflammation as a promising target for the treatment of AD. Natural plants have attracted many researchers to screen for candidate agents because of their extensive pharmacological activities and few adverse effects. In our group, isoforsythiaside has been confirmed to inhibits ferroptosis and neuroinflammation in erastin-damaged HT22 cells and APP/PS1 mice, at least partially by regulating the activation of Nrf2 and NF-κB signaling. Furthermore, Forsythoside A (FA), the main ingredient in Forsythia suspensa (Thunb.) Vahl, possesses anti-inflammatory, anti-bacterial, anti-oxidant and neuroprotective activities. We first revealed the anti-AD properties of FA via modulation of ferroptosis-mediated neuroinflammation by targeting the activation of the Nrf2/GPX4 axis. According to our data, the inactivation of the Nrf2/GPX4 axis activates the NF-κB signaling, which further aggravates neuroinflammation.
