[HTML][HTML] Antiparallel triple-strand architecture for prefibrillar Aβ42 oligomers
Aβ42 oligomers play key roles in the pathogenesis of Alzheimer disease, but their structures
remain elusive partly due to their transient nature. Here, we show that Aβ42 in a fusion …

[HTML][HTML] Ring-like N-fold Models of Aβ42 fibrils
W Xi, UHE Hansmann - Scientific Reports, 2017 - nature.com
When assembling as fibrils Aβ40 peptides can only assume U-shaped conformations while
Aβ42 can also arrange as S-shaped three-stranded chains. We show that this allows Aβ42 …
