Evaluating anorexia-related brain atrophy using MP2RAGE-based morphometry

Tobias Kober, Bénédicte Marie Maréchal, Alexis Roche, François Lazeyras

To evaluate brain atrophy in anorexic patients by automated cerebral segmentation with the magnetization-prepared 2 rapid acquisition gradient echo (MP2RAGE) MRI sequence. Twenty patients (female; mean age, 27.9 years), presenting consecutively for brain M ...

Dopamine induces soluble alpha-synuclein oligomers and nigrostriatal degeneration

Elpida Tsika

Parkinson's disease (PD) is defined by the loss of dopaminergic neurons in the substantia nigra and the formation of Lewy body inclusions containing aggregated alpha-synuclein. Efforts to explain dopamine neuron vulnerability are hindered by the lack of do ...

The mechanism of sirtuin 2-mediated exacerbation of alpha-synuclein toxicity in models of Parkinson disease

Hilal Lashuel, Bruno Claude Daniel Fauvet, Magdalena Zweckstetter, Sebastian Kugler

Sirtuin genes have been associated with aging and are known to affect multiple cellular pathways. Sirtuin 2 was previously shown to modulate proteotoxicity associated with age-associated neurodegenerative disorders such as Alzheimer and Parkinson disease ( ...

Modulation of AMPK's activity via genetic tools and food-derived compounds as a novel approach to Parkinson's disease treatment

Wojciech Janusz Bobela

Aging is considered as a major risk factor for Parkinsonâs disease (PD) and can be defined as a gradual decline in the ability of biological systems to efficiently renew structural and functional components, which may lead to perturbations in energetic h ...

Induction of de novo α-synuclein fibrillization in a neuronal model for Parkinson's disease

Hilal Lashuel, Bohumil Maco, Abid Oueslati, Mohamed Bilal Fares

Lewy bodies (LBs) are intraneuronal inclusions consisting primarily of fibrillized human α-synuclein (hα-Syn) protein, which represent the major pathological hallmark of Parkinson's disease (PD). Although doubling hα-Syn expression provokes LB pathology in ...

Erythropoietin Restores Long-Term Neurocognitive Function Involving Mechanisms of Neuronal Plasticity in a Model of Hyperoxia-Induced Preterm Brain Injury

Yohan Van de Looij

Cerebral white and grey matter injury is the leading cause of an adverse neurodevelopmental outcome in prematurely born infants. High oxygen concentrations have been shown to contribute to the pathogenesis of neonatal brain damage. Here, we focused on moto ...

Cerebellar Ataxia and Coenzyme Q Deficiency through Loss of Unorthodox Kinase Activity

Matteo Dal Peraro, Deniz Aydin, Xiao Guo

The UbiB protein kinase-like (PKL) family is widespread, comprising one-quarter of microbial PKLs and five human homologs, yet its biochemical activities remain obscure. COQ8A (ADCK3) is a mammalian UbiB protein associated with ubiquinone (CoQ) biosynthesi ...

alpha-Synuclein strains cause distinct synucleinopathies after local and systemic administration

Michele Giugliano

Misfolded protein aggregates represent a continuum with overlapping features in neurodegenerative diseases, but differences in protein components and affected brain regions(1). The molecular hallmark of synucleinopathies such as Parkinson's disease, dement ...

Recapitulating De Novo Alpha-Synuclein Fibrillization in a Novel Neuronal Model of Parkinson's Disease

Mohamed Bilal Fares

Athough it has been established for over 100 years that Lewy bodies (LBs) represent the major pathological hallmark of Parkinson's disease (PD), we still do not know why these fibrillar intra-neuronal inclusions of the α-Synuclein (α-Syn) protein form, and ...

Parkinson's Disease Genes VPS35 and EIF4G1 Interact Genetically and Converge on α-Synuclein

Hilal Lashuel, Klodjan Stafa, Simona Eleuteri

Parkinson's disease (PD) is a common neurodegenerative disorder. Functional interactions between some PD genes, like PINK1 and parkin, have been identified, but whether other ones interact remains elusive. Here we report an unexpected genetic interaction b ...
