Misfolding of amyloidogenic proteins at membrane surfaces: the impact of macromolecular crowding.
The presence of inert macromolecular crowding agents mimics the situation in vivo where amyloidogenic proteins are released into an aqueous, congested intracellular environment. By using the amphiphatic Alzheimer Abeta-protein as the model system, the presence of a three-dimensional macromolecular crowding environment enhanced significantly its misfolding behavior if charged membrane surfaces as two-dimensional aggregation templates were present.
