    Impaired lysophagy function exacerbates propagation of α-synuclein aggregation

    K. Kakuda, K. Ikenaka, C. Aguirre, C. Choong, J. Doi, Y. Kimura, H. Mochizuki (Osaka, Japan)

    Objective: We aimed to clarify how exogenous αSyn aggregates interact with native αSyn in the cytoplasm and seed aggregation, and what defense mechanisms protect against…

    Evaluation of small extracellular vesicles derived miRNA as biomarkers for Parkinson’s disease: comparison with plasma miRNA

    S. Rai, P. Bharti, R. Singh, R. Rajan, S. Kumar (New Delhi, India)

    Objective: To identify differentially expressed small extracellular vesicles (sEV) derived miRNAs in Parkinson’s disease using small RNA-sequencing and to evaluate their potential as biomarker targets.…

    IP-RT-QuIC Identify Disease-Specific Alpha-Synuclein Seeds in serum from patients with syncleinopathy

    A. Okuzumi, T. Hatano, G. Matsumoto, N. Hattori (Tokyo, Japan)

    Objective: To examine whether alpha-synuclein (aSyn) seed exists in the serum and its potential as a serum biomarker. Background: Parkinson’s disease (PD) and Multiple system…

    Glucocerebrosidase (GCase) activator, Ambroxol, reduces alpha-synuclein serine-129 phosphorylation and oligomers in mutant LRRK2 R1441G mouse brains

    Z. Choi, E. Chang, H. Liu, S. Zhang, Y. Ruan, K. Leung, S. Pang, M. Kung, D. Ramsden, S. Ho, P. Ho (Hong Kong, Hong Kong)

    Objective: To explore whether inducing brain GCase activity by Ambroxol™ (ABX; a brain-penetrant GCase activator) can reduce a-synuclein (αSyn) serine-129 phosphorylation and oligomer accumulation in…

    Lysosomal-driven reduction of alpha-synuclein aggregates in a neuron-like model of Parkinson’s disease

    S. Lucas-Del-Pozo, G. Uras, F. Fierli, AHV. Schapira (London, United Kingdom)

    Objective: To test whether PIKfyve inhibition results in a lysosomal-driven reduction of alpha-synuclein aggregates in a mutant neuroblastoma cell line overexpressing an aggregation-prone form of…

    SLP-2 modulated expression rescues mitochondrial function in alpha-synuclein neuropathology models

    M. Castelo, G. Gentile, A. Zanon, A. Lavdas, C. Bolduc, M. Picon, S. Laouafa, J. Soliz, M. Lévesque, I. Pichler (Bolzano, Italy)

    Objective: Validate the rescue potential of SLP-2 induction for α-synuclein (aSyn)-induced mitochondrial pathology and neurodegeneration in two complementary models: human induced pluripotent stem cell (hiPSC)-derived…

    The Role of Adaptive Immunity caused by α-synuclein Recognition Specific Sequence Peptide on the Onset of Parkinson’s Disease Pathogenesis

    MG. Jo, BN. Lee, HM. Seong, SH. Kim, HN. Choi, MG. Kim, SP. Yun (Jinju, Republic of Korea)

    Objective: We investigated whether α-synuclein-derived peptides (recognized specific sequence in α-synuclein) can drive T-cell response and evaluated the neurotoxicity of α-synuclein peptide-specific T-cell in Parkinson’s…
