| Research Abstract |
Alzheimer's disease is pathologically featured by extraneuronal deposition of amyloid fibrils, which are composed of amyloid-β protein (Aβ). However, it still remains to be clarified how soluble monomeric Aβ assemble into fibrils. In the present study, we found that ganglioside GM1 is release from mouse primary cortical neurons, in the association with exosome. Furthermore, the exosome-associated GM1 accelerated the assembly of synthetic Aβ in vitro.
