摘要
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 A beta-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.
