Oligomer formation of amyloid-beta peptides (A beta) is accelerated at a hydrophilic/hydrophobic interface. However, details of the acceleration mechanism have not been elucidated. To understand the effects of the interface on oligomerization at the atomic level, we performed molecular dynamics simulations for an A beta 40 monomer in the presence and absence of the hydrophilic/hydrophobic interface. Nuclear magnetic resonance experiments of A beta 40 peptides with gangliosidic micelles were also carried out. In the simulations and experiments, the hydrophobic residues of A beta 40 bound to the interface stably. Moreover, we found that A beta 40 formed a hairpin structure at the interface more readily than in bulk water. From these results, we discussed the acceleration mechanism of the oligomer formation at the interface.
