Alzheimer's disease (AD) is a complex neurodegenerative disorder with multifaceted pathogenesis, which has been extensively investigated, yet effective treatments remain lacking. Splicing factor proline and glutamine rich (SFPQ) is known to play a crucial role in neurodegenerative diseases, including antioxidant-related functions and regulating gene expression within brain neurons. However, the specific role of SFPQ in AD pathology is not well understood. In this study, an AD mouse model was established through lateral ventricular injection of amyloid-beta
