Brain α-synuclein deposits are the hallmark of various distinct neurodegenerative diseases, and it is proposed that α-synuclein assemblies with different structural characteristics or 'strains' (ribbons or fibrils) could account for pathological differences between these diseases; here different human α-synuclein strains are injected into rat brain, and are shown to propagate in a strain-dependent manner and cause different pathological and neurotoxic phenotypes.
