Electric Field Effect on Inhibiting the Co-fibrillation of Amyloid Peptides by Modulating the Aggregation Pathway
With the revelation of the close
link between Alzheimer’s
disease (AD) and type II diabetes (T2D) and the possible assembly
of multiple amyloid peptides therein, it is critical to understand
and regulate the co-fibrillation pathway between related amyloid peptides.
Here, we show experimentally and theoretically that electric field
(EF) inhibited hybrid amyloid fibrillation of β-amyloid peptide
(Aβ) and human islet amyloid peptide (hIAPP) by modulating the
hetero-aggregation pathway. Experimental results confirm that the
β-sheet secondary structure of amyloid peptides would be disrupted
under small static EF and accompanied by transforming fibril aggregates
into amorphous particles in vitro. Molecular dynamics simulations
further demonstrate that even with the transformation of the secondary
structure from β-sheet to random coil, the strong interaction
between Aβ and hIAPP peptides would remain largely unaffected
under the small static EF, leading to the formation of amorphous nanoparticles
observed in the experiments. This inhibitory effect of EF on the co-fibrillation
of multiple amyloid peptides might contribute to reducing the mutual
deterioration of different degenerative diseases and show great potential
for the noninvasive treatment of amyloid-related diseases
