[NSF-02] Intra- & into-the- brain propagation of α-synuclein: significance for the pathogenesis, progression and therapeutic target of Lewy body diseases

Thu. May 24, 2018 3:20 PM - 5:20 PM Room 2 (Sapporo Geibunkan / Zuisetsu (3F))

The Braak’s Staging of PD brain pathology provides useful information about staged distribution of Lewy bodies or α-synuclein (αSyn) deposition, with later stages correlating with clinical aspects of the disease. In this hypothesis, αSyn deposits begins from the lower brainstem or olfactory bulb, spreads rostrally and reaches to parkinsonism-causing SN and finally to the cerebral cortex. The concept attracted much attention, as it seems to explain the clinical course of PD from prodromal phase to PD with dementia. In this seminar, to understand the mechanism of propagation system of αSyn in PD, DLB and MSA, we organized the distinguished expert in this area. We also discuss with the future treatment against this system of αSyn.
