    An agent-based model replicates the pathogenic spread of alpha-synuclein in mice

    S. Rahayel, B. Mišić, Y.Q Zheng, Z.Q Liu, A. Caputo, K. Luk, A. Dagher (Montreal, QC, Canada)

    Objective: To investigate the ability of a susceptible-infected-removed (SIR) agent-based model to predict the pathogenic spread of alpha-synuclein fibrils after injection in mice. Background: Parkinson’s…

    Difference in distribution between alpha-synuclein oligomers and Lewy bodies in Parkinson’s disease brain

    H. Sekiya, H. Kowa, Y. Hashimoto, M. Takata, R. Matsumoto, T. Toda (Kobe, Japan)

    Objective: To examine the distribution of alpha-synuclein (αSYN) oligomers in Parkinson’s disease (PD) brains and compare the distribution of αSYN oligomers and Lewy bodies. Background:…

    The exosomal a-syn filaments can be a novel biomarker of Parkinson’s disease

    Y. Ishiguro, T. Tsunemi, A. Yoroisaka, N. Hattori (Tokyo, Japan)

    Objective: This study is aimed to investigate whether the number of exosomes, the amount of total or exosomal a-synuclein (a-syn) filaments in serum can serve as…
