The interactions of amyloid ß aggregates with phospholipid membranes and the implications for neurodegeneration.

ABSTRACT

Misfolding, aggregation and accumulation of Amyloid-ß peptides (Aß) in neuronal tissue and extracellular matrix are hallmark features of Alzheimer's disease (AD) pathology. Soluble Aß oligomers are involved in neuronal toxicity by interacting with the lipid membrane, compromising its integrity, and affecting the function of receptors. These facts indicate that the interaction between Aß oligomers and cell membranes may be one of the central molecular level factors responsible for the onset of neurodegeneration. The present review provides a structural understanding of Aß neurotoxicity via membrane interactions and contributes to understanding early events in Alzheimer's disease.
