Alzheimer’s disease (AD) is a devastating neurodegenerative disorder and the most common cause of
dementia. Today, only palliative therapies are available. The pathological hallmarks of AD are the presence of
neurofibrillary tangles and amyloid plaques, mainly composed of the amyloid-β peptide (Aβ), in the brains of the patients.
Several lines of evidence suggest that the increased production and/or decreased cleavage of Aβ and subsequent
accumulation of Aβ oligomers and aggregates play a fundamental role in the disease progress. Therefore, substances
which bind to Aβ and influence aggregation thereof are of great interest. A wide range of Aβ binding peptides were
investigated to date for therapeutic purposes. Only very few were shown to be effective in rodent AD models or in clinical
studies. Here, we review those peptides and discuss their possible mechanisms of action.
