    Lysosomal network defects in parkinsonian patients carrying rare variants in lysosomal hydrolytic enzyme genes

    J. Hoenicka, A. Pascual, O. de Fàbregues, M. Frias, L. Vela, M. de Lucca, P. García-Ruiz, C. Feliz, M. Marchen, R. Repossi, G. Fernández, M. Roldán, F. Palau (Esplugues de Llobregat, Spain)

    Objective: Functional validation of rare variants of lysosomal genes potentially associated with early onset Parkinson's disease (EOPD) Background: The genetic load in EOPD is high;…

    V-ATPase subunit V1G1 overexpression conferred the mice neuroprotection during MPTP exposure

    YIM. Wang, Y. Li, Y. Xia, L. Kou, T. Wang (武汉市, China)

    Objective: Elucidating the role of lysosomal dysfunction due to altered stability and expression levels of V-type proton ATPase subunit G (V1G1) in the degradation and…
  • 2023 International Congress

    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…

    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…
  • 2023 International Congress

    The spectrum of GBA mutations in the Korean population with Parkinson’s disease

    J. Hwangbo, J. Lee, SC. Cheon, KS. Park (Yangsan, Republic of Korea)

    Objective: We investigated the mutation spectrum of glucocerebrosidase (GBA) gene in Korean patients with Parkinson’s disease (GBA-PD). Background: Mutations in the GBA gene represent important…

    Cholinergic topography and clinical profile of early Parkinson’s patients with GBA mutations

    S. Slingerland, S. Vander Zee, G. Carli, A. Slomp, J. Boertien, T. van Laar (Groningen, Netherlands)

    Objective: To explore the regional cholinergic innervation and clinical profile of early Parkinson’s disease (PD) patients carrying GBA mutations (GBA-PD). Background: The most common genetic…
  • 2023 International Congress

    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…
  • 2023 International Congress

    A juvenile onset Sandhoff disease case caused by hemizygous mutations of HEXB

    JH. Yin (Beijing, China)

    Objective: Sandhoff disease (SD) is a rare neurological disease with high clinical heterogeneity. SD in juvenile form is much rarer and it is often misdiagnosed…
  • 2022 International Congress

    Polymorphisms in Prosaposin gene are associated with familial and early-onset Parkinson’s disease: A case-control association study and meta-analysis

    YT. Chu, MC. Kuo, YA. Su, RM. Wu (Taipei, Taiwan)

    Objective: To investigate the role of the PSAP gene in PD patients in Taiwan, including familial PD and early-onset Parkinson’s disease. Background: Mutations in the…

    Investigation of Modifiers of β-Glucocerebrosidase in Cell Models of Parkinson’s Disease

    A. Wernick, J. Evans, G. Virdi, M. Choi, D. Athauda, Z. Zanjani Shadman, H. Plun-Favreau, S. Wray, S. Gandhi (London, United Kingdom)

    Objective: We firstly aim to identify modifiers of β-glucocerebrosidase (GCase) activity and expression in Parkinson’s disease (PD) relevant cell models. We secondly aim to ascertain…
