  • Abstract
  • Look Inside

The conversion of soluble, nontoxic amyloid β-protein (Aβ) to aggregated, toxic Aβ rich in β-sheet structures by seeded polymerization is considered to be the key step in the development of Alzheimer's disease (AD). GM1 ganglioside-bound amyloid β-protein (GM1-Aβ), found in brains exhibiting early pathological changes of AD plaques, has been suggested to accelerate amyloid fibril formation by acting as a seed. Aβ recognizes a GM1 cluster, the formation of which is facilitated by cholesterol.
