Abstract:
The interaction of beta-amyloid (Abeta) peptides with externally applied electric fields (EF) of varying strengths was investigated by means of molecular dynamics (MD) simulations. The results suggest that the EF favors the switch of Abeta-peptides from helical to beta-sheet conformation, and a mechanism is tentatively proposed. Switching off the field does not restore the original conformation.

Amyloid Fibrils
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining, normally used to...
