"Exosomes extracted from brains diagnosed with either Alzheimer's disease or Dementia with Lewy Bodies (DLB)contained aggregate-prone proteins. Furthermore injection of brain-derived exosomes from DLB patients into the brains of wild type mice induced alpha-synuclein (alpha-syn) aggregation. Data imply exosomes may play a role in alpha-syn pathogenesis possibly through the seeding of toxic forms of alpha-syn."xsd:string
