Far-UV Circular Dichroism experiments and Atomic Force Microscopy tomography are employed to assess the impact of β-sheet breakers on the Aβ1-40 peptide aggregation process in the presence of Cu2+ or Zn2+ transition metals. In this work we focus on two specific 5-amino acids long β-sheet breakers, namely the LPFFD Soto peptide, already known in the literature, and the LPFFN peptide recently designed and studied by our team. We provide evidence that both β-sheet breakers are effective in reducing the Aβ1-40 aggregation propensity, even in the presence of metal ions.

Abstract

Far-UV Circular Dichroism experiments and Atomic Force Microscopy tomography are employed to assess the impact of β-sheet breakers on the Aβ1-40 peptide aggregation process in the presence of Cu2+ or Zn2+ transition metals. In this work we focus on two specific 5-amino acids long β-sheet breakers, namely the LPFFD Soto peptide, already known in the literature, and the LPFFN peptide recently designed and studied by our team. We provide evidence that both β-sheet breakers are effective in reducing the Aβ1-40 aggregation propensity, even in the presence of metal ions.
