Alzheimer's disease (AD) is a neurodegenerative associated with human aging. Ten percent of individuals over 65 years have AD and its prevalence continues to rise increasing age. There are currently no effective modifying treatments for AD, resulting in increasingly large socioeconomic personal costs. Increasing age an increase low-grade chronic inflammation (inflammaging) that may contribute the process AD.

Epilepsy is one of the most common neurological disorders in childhood. However, classical antiepileptic drugs are linked with drug toxicity and cognitive function impairment children. Hence, it essential to develop a novel therapy solve this problem. Currently, studies indicate regulating nuclear factor-erythroid 2-related factor 2 (Nrf2)-mediated ferroptosis pathway represents potential advanced for seizures. present study aimed explore whether quercetin, natural polyphenol, could alleviate seizure-induced neuron death preserve by inhibiting Nrf2-mediated ferroptosis.Kainic acid-induced epileptic mice model, morris water maze (MWM) test, cell counting kit-8 (CCK-8) assays, western blotting analysis, enzyme-linked immunosorbent assay, flow cytometry, quantitative real-time reverse transcription PCR (qRT-PCR), immunofluorescence staining, RNA sequencing analysis were employed mechanisms which quercetin exerts protective effects on kainic model glutamate-induced HT22 neuronal death.Our findings suggested association between seizures clinical setting.
