Is interaction of amyloid β-peptides with metals involved in cognitive activity?

Metal ions, i.e., Zn2+ and Cu2+, are released from neuron terminals in the hippocampus, which plays important roles in spatial and declarative memory, and may serve as a signal factor. Aβ is bound to Zn2+ and Cu2+ in the extracellular compartment and forms oligomers, potentially followed by transiently cognitive decline.
