    CHAPERONIC PROPENSITIES OF AFRICAN WALNUT AS A THERAPEUTIC TARGET IN MANGANESE-INDUCED PARKINSON-LIKE NEUROPATHOLOGY IN WISTAR RATS

    O. Tokunbo, B. Enaibe, T. Abayomi (Osogbo, Nigeria)

    Objective: Herein, the chaperonic propensities of ethanolic extract of African walnut (WNE) in Manganese-induced Parkinson-like neuropathology in the prefrontal cortex and hippocampus was investigated. Background:…

    Rapamycin attenuates nigral and hippocampal alpha-synuclein accumulation in AAV-mediated alpha-synuclein overexpression model of Parkinson’s disease

    E. Cinar, G. Yalcin-Cakmakli, A. Ulusoy, E. Saka, B. Tel, B. Elibol (Zonguldak, Turkey)

    Objective: To examine the possible neurorestorative effects of chronic rapamycin treatment in AAV-mediated alpha-synuclein (a-syn) overexpression model of Parkinson’s disease (PD), designed to induce hippocampal…

    Cerebral microvascular injury provoked by alpha-synuclein preformed fibrils exacerbates cognitive dysfunction in Parkinson’s disease

    Q.X Zhang, Y.Y Gao, L.J Wang (Guangzhou, China)

    Objective: The aim of this study was to investigate the role of microvascular pathology between abnormal αSyn aggregation and PD cognitive dysfunction. Background: Higher plasma…

    α-Synuclein propagation via olfactory pathway induces olfactory bulb atrophy and widespread glucose hypometabolism in a non-human primate model

    M. Sawamura, H. Onoe, H. Tsukada, K. Isa, N. Uemura, T. Isa, R. Takahashi (Kyoto, Japan)

    Objective: We investigated how α-synuclein (α-Syn) pathology spreads from the olfactory bulb (OB) and how the pathology affects brain structure and activity. Background: Parkinson's disease…

    Spreading ɑ-synuclein pathology initiated from the sublaterodorsal tegmental nucleus models RBD followed by Parkinsonian phenotypes in mice

    Y. Shen, W.B Yu, B. Shen, H. Dong, J. Zhao, Y. Fan, Y.F Yang, Y.M Sun, Y.L Tang, F.T Liu, JJ. Wu, B.G Xiao, H. Yu, J. Koprich, Z.L Huang, J. Wang (Shanghai, China)

    Objective: To recapitulate ɑ-synucleinopathy based RBD-like behaviors in mice which could further proceed to develop Parkinsonian behavioral and histopathological phenotypes. Background: Idiopathic REM sleep behavior…

    GCI-induced neurodegeneration and synucleinopathy in non-human primates

    M. Teil, S. Dovero, M.L Artocarena, M. Bourdenx, G. Porras, B. Mollenhauer, M.T Herrero, M. Vila, J. Obeso, B. Dehay, E. Bezard (Bordeaux, France)

    Objective: This study aimed at determining the potential to induce MSA pathology in non-human primates. Background: Aggregation of alpha-synuclein has been implicated in several neurodegenerative…

    Protective role of astrocytes on α-synuclein accumulation and propagation

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

    Objective: This study is aimed to investigate the role of astrocytes on the accumulation and propagation of α-synuclein (a-syn), the main component of Lewy bodies/neurites,…

    Mixed pathologies in pancreatic beta-cells from subjects with neurodegenerative diseases and their interaction with prion protein

    R. Valenti, I. Martinez, I. Amat, I. Marcilla, G. Marti, L. Armengou, C. Caballero, M.R Luquin (Pamplona, Spain)

    Objective: We studied whether, as in the brain, pancreatic -cells of subjects with neurodegenerative diseases also present co-occurrence of other misfolded proteins. Furthermore, we also assessed…
