Molecular mechanisms of amyloid disaggregation

The resulting products of disaggregation are not characterized in detail at the molecular level for most of the studied systems. According to the amyloid aggregation cascade hypothesis, amyloid fibrils are formed by the aggregation of monomers, followed by the aggregation of the resulting oligomers (Review).Hence, the solubilization of amyloid fibrils could result in the formation of …
