The generation of a pathogenic molecule through protein misfolding cycling amplification (PMCA) in the presence of phospholipid is reminiscent of the "globulomer" complex formed from Aβ and specific lipids (Barghorn et al., 2005). There may also be some relationship to the role of gangliosides in creation of a toxic Aβ moiety (Kakio et al., 2002; Yamamoto et al., 2007). Perhaps lipid-protein interactions play a general and critical role in the development of peptide misfolding disorders.
