    Ionic Plasticity of Midbrain GABAergic Synapses in PD Models

    A. Borgkvist, E. Bezard, M. Molinari, E. Santini, M. Canron (Solna, Sweden)

    Objective: To validate that enhancing potassium-chloride cotransporter activity would restore inhibition and normal function in parkinsonian Substantia nigra reticulata (SNr) and participate to Parkinson’s disease (PD) symptom alleviation. Background: The SNr is an output nucleus…

    The neuroprotective properties of NLX-112 in MPTP treated mice are mediated by reactive gliosis and astrocytic GDNF

    W. Powell, A. Newman-Tancredi, L. Annett, R. Depoortere, M. Iravani (Hatfield, United Kingdom)

    Objective: To investigate whether NLX-112, a potent and selective 5-HT1A agonist is neuroprotective in a mouse MPTP model of Parkinson’s Disease (PD) [1]. Background: There…

    An in-vivo study of the integrity of the nigrostriatal pathways in drug-naive Parkinson’s disease patients using [11C]PE2I PET and neuromelanin-Magnetic Resonance Imaging

    G. Pagano, H. Wilson, E. de Natale, F. Niccolini, S. Polychronis, T. Yousaf, R. Gunn, E. Rabiner, M. Mehta, M. Politis (Basel, Switzerland)

    Objective: This study evaluated the relationship between the neurodegeneration of the substantia nigra neurons, assessed using Neuromelanin-sensitive MRI, and of the loss of striatal dopaminergic…

    Agreement between swallow tail sign asymmetry and clinical laterality in Parkinson’s disease

    M. Rohonczi, G. Perlaki, G. Hernádi, N. Kovács (Pécs, Hungary)

    Objective: Our goal was to evaluate the concordance between asymmetry in nigral hyperintensity detected with 3T MRI and clinical symptomatology. Background: A promising MRI marker…
