Structural details of amyloid beta oligomers in complex with human prion protein as revealed by solid-state MAS NMR spectroscopy
Human PrP (huPrP) is a high-affinity receptor for oligomeric amyloid-? (A?) protein aggregates. Binding of A? oligomers to membrane-anchored huPrP has been suggested to trigger neurotoxic cell signaling in Alzheimer's disease, while an N-terminal soluble fragment of huPrP can sequester A? oligomers and reduce their toxicity. Synthetic oligomeric A? species are known to be heterogeneous, dynamic and transient, rendering their structural investigation particularly challenging. Here, using huPrP to...
