Cofilin 2 in Serum as a Novel Biomarker for Alzheimer’s Disease in Han Chinese

Published on August 10, 2019

The identification of biomarkers of Alzheimer’s disease (AD) is an important and urgent area of study, not only to aid in the early diagnosis of AD, but also to evaluate potentially new anti-AD drugs. The aim of this study was to explore cofilin 2 in serum as a novel biomarker for AD. The upregulation was observed in AD patients and different AD animal models compared to the controls, as well as in AD cell models. Memantine and donepezil can attenuate the upregulation of cofilin 2 expression in APP/PS1 mice. The serum levels of cofilin 2 in AD or mild cognitive impairment (MCI) patients were significantly higher compared to controls (AD: 167.9±35.3 pg/mL; MCI: 115.9±15.4 pg/mL; Control: 90.5±27.1 pg/mL; p
