Fibril Conformation as the Basis of Species- and Strain-Dependent Seeding Specificity of Mammalian Prion Amyloids

Spongiform encephalopathies are believed to be transmitted by self-perpetuating conformational conversion of the prion protein. It was shown recently that fundamental aspects of mammalian prion propagation can be reproduced in vitro in a seeded fibrillization of the recombinant prion protein variant Y145Stop (PrP23-144). Here we demonstrate that PrP23-144 amyloids from different species adopt d...

Sequence dependent aggregation of peptides and fibril formation.

Deciphering the links between amino acid sequence and amyloid fibril formation is key for understanding protein misfolding diseases. Here we use Monte Carlo simulations to study the aggregation of short peptides in a coarse-grained model with hydrophobic-polar (HP) amino acid sequences and correlated side chain orientations for hydrophobic contacts. A significant heterogeneity is observed in th...

Flavone Derivatives as Inhibitors of Insulin Amyloid-Like Fibril Formation

Several natural and synthetic flavone derivatives have been reported to inhibit formation of amyloid fibrils or to remodel existing fibrils. These studies suggest that the numbers and positions of hydroxyl groups on the flavone rings determine their effectiveness as amyloid inhibitors. In many studies the primary method for determining the effectiveness of inhibition is measuring Thioflavin T (...
