摘要: Parkinson’s disease (PD) is the most common movement disorder and the 2nd most common neurodegenerative diseases after Alzheimer’s disease. The hallmarks of the PD neuropathology are dopaminergic cell death in the substantia nigra of the midbrain (largely resulting in the motor symptoms) and protein (alpha-synuclein) aggregation. We recently showed evidence of alpha-synuclein cell-to-cell transfer using in vitro and in vivo models of PD. We also demonstrated that human alpha-synuclein and its aggregates can propagate from the intestine to the brain in long-distance after being administered in the gut by local protein injection or viral transduction. Live cell imaging indicates that both slow and fast components of axonal transport are involved in the trafficking of aggregated alpha -synuclein. These findings indicate that the prion-like property of alpha-synuclein is important for initiation and progression of PD pathology, thus, it holds promise as a new avenue for the development of future PD therapeutics.
