Soluble oligomers arising from the aggregation of the amyloid beta peptide (Aβ) have been identified as the main pathogenic agents in Alzheimer's disease (AD). Prefibrillar oligomers of the 42‐residue form of Aβ (Aβ42O) show membrane‐binding capacity and trigger the disruption of Ca2+ homeostasis, a causative event in neuron degeneration. Since bioactive lipids have been recently proposed as potent...
Increasing evidence supports the idea that the initial events of Aβ oligomerization and cytotoxicity in Alzheimer's disease involve the interaction of amyloid Aβ-derived diffusible ligands (ADDLs) with the cell membrane. This also indicates lipid rafts, ordered membrane microdomains enriched in cholesterol, sphingolipids and gangliosides, as likely primary interaction sites of ADDLs. To shed further...
