Autoantibodies in Alzheimer’s disease:potential biomarkers,pathogenic roles,and therapeutic implications

摘要：Alzheimer’s disease(AD) is a prevalent and debilitating neurodegenerative disorder in the elderly.The etiology of AD has not been fully defined and currently there is no cure for this devastating disease.Compelling evidence suggests that the immune system plays a critical role in the pathophysiology of AD.Autoantibodies against a variety of molecules have been associated with AD.The roles of these autoantibodies in AD,however,are not well understood.This review attempts to summarize recent findings on these autoantibodies and explore their potential as diagnostic/prognostic biomarkers for AD,their roles in the pathogenesis of AD,and their implications in the development of effective immunotherapies for AD.
