Abstract

We examined the ultrastructural localization of oligomeric proteins, Aβ42, and flotillin-1 in Tg2576 mouse brains by triple immunoelectron microscopy. Oligomer-specific immunoreactions localized to cell processes, especially to axon terminals with higher density in Tg than in nonTg mouse brains. The oligomer was less frequently colocalized to flotillin-1- immunoreactive rafts than Aβ42, suggesting that rafts are one of the sites of polymeric Aβ deposition, but not of oligomeric proteins including Aβ.
