摘要
α-Synucleinopathies,such as Parkinson’s disease(PD),dementia with Lewy bodies(DLB)and multiple system atrophy,are a class of neurodegenerative diseases exhibiting intracellular inclusions of misfoldedα-synuclein(αSyn),referred to as Lewy bodies or oligodendroglial cytoplasmic inclusions(Papp-Lantos bodies).Even though the specific cellular distribution of aggregatedαSyn differs in PD and DLB patients,both groups show a significant pathological overlap,raising the discussion of whether PD and DLB are the same or different diseases.Besides clinical investigation,we will focus in addition on methodologies,such as protein seeding assays(real-time quaking-induced conversion),to discriminate between different types ofα-synucleinopathies.This approach relies on the seeding conversion properties of misfoldedαSyn,supporting the hypothesis that different conformers of misfoldedαSyn may occur in different types ofα-synucleinopathies.Understanding the pathological processes influencing the disease progression and phenotype,provoked by differentαSyn conformers,will be important for a personalized medical treatment in future.
