Revisiting the specificity and ability of phospho-S129 antibodies to capture alpha-synuclein biochemical and pathological diversity

Christian Iseli, Nicolas Jean Philippe Guex, Hilal Lashuel, Anass Chiki, Ramanath Narayana Hegde, Anne-Laure Mahul Mellier, Ritwik Burai, Sean Michael Deguire, Melek Firat Altay, Sonia Donzelli, Jonathan Jean-Pierre Ricci, Salvatore Novello, Pedro José Santana Ribeiro Magalhães, Yllza Jasiqi

Antibodies against phosphorylated alpha-synuclein (aSyn) at 5129 have emerged as the primary tools to investigate, monitor, and quantify aSyn pathology in the brain and peripheral tissues of patients with Parkinson's disease and other neurodegenerative dis ...

Towards elucidating the structural and cellular determinants of a-synuclein seeding and toxicity

Somanath Jagannath

Although it has been nearly two and half decades since the discovery of alpha-synuclein (aSyn) as the major component of Lewy bodies (LBs), our understanding of the involvement of different aSyn species, their seeding, spreading and toxicity in Parkinson's ...

Transposon-activated POU5F1B promotes colorectal cancer growth and metastasis

Didier Trono, Laurence Gouzi Abrami, Julien Léonard Duc, Sandra Eloise Kjeldsen, Alexandre Coudray, Sagane Dind, Evaristo Jose Planet Letschert, Laia Simo Riudalbas

The treatment of colorectal cancer (CRC) is an unmet medical need in absence of early diagnosis. Here, upon characterizing cancer-specific transposable element-driven transpochimeric gene transcripts (TcGTs) produced by this tumor in the SYSCOL cohort, we ...

Trans‐seeding of Alzheimer‐related tau protein by a yeast prion

Henning Paul-Julius Stahlberg, Zhiva Skachokova

Abnormal tau protein aggregates constitute a hallmark of Alzheimer's disease. The mechanisms underlying the initiation of tau aggregation in sporadic neurodegeneration remain unclear. Here we investigate whether a non-human prion can seed tau aggregation. ...

Computational Studies of the Proton-Coupled Metal Ion Transport in the SLC11/NRAMP Family of Transporters

Maria Letizia Merlini

In the last years, it has been demonstrated a link between the overload of metal ions inside nervous system cells and the onset of severe neurodegenerative diseases. This prompted the investigation of the structural and functional properties of transporter ...

Dopamine Transporter, PhosphoSerine129 alpha-Synuclein and alpha-Synuclein Levels in Aged LRRK2 G2019S Knock-In and Knock-Out Mice

Salvatore Novello, Chiara Domenicale

The G2019S mutation in leucine rich-repeat kinase 2 (LRRK2) is a major cause of familial Parkinson's disease. We previously reported that G2019S knock-in mice manifest dopamine transporter dysfunction and phosphoSerine129 alpha-synuclein (pSer129 alpha-syn ...

Second harmonic scattering of water in a biological context

Tereza Schönfeldová

Water is one of the most abundant molecules in the universe. It forms a hydrogen bond network with unique structure and dynamics. Hydrogen bonding is highly relevant to many biological processes including membrane formation, protein folding, adsorption, an ...

Metabolic regulation of cytokinesis in Schizosaccharomyces pombe

Özge Uysal Özdemir

All cells need to be able to sense their environment, and adapt their metabolism, growth and cell division appropriately. In this study, I examined the response of Schizosaccharomyces pombe to a change in the carbon source and how that affects cytokinesis. ...

Reverse engineering Lewy bodies: how far have we come and how far can we go?

Hilal Lashuel, Mohamed Bilal Fares, Somanath Jagannath

Lewy bodies (LBs) are α-synuclein (α-syn)-rich intracellular inclusions that are an important pathological hallmark of Parkinson disease and several other neurodegenerative diseases. Increasing evidence suggests that the aggregation of α-syn has a central ...

Alpha-synuclein research: defining strategic moves in the battle against Parkinson's disease

Hilal Lashuel, Magdalena Zweckstetter

With the advent of the genetic era in Parkinson's disease (PD) research in 1997, alpha-synuclein was identified as an important player in a complex neurodegenerative disease that affects >10 million people worldwide. PD has been estimated to have an econom ...

Enhancing mitochondrial quality control to fight neuromuscular degeneration in aging and disease

Mario Romani

Loss of mitochondrial function and proteostasis typify aging and age-associated degenerative disorders such as Alzheimer's disease and muscle aging. To date, no cure or preventive measure is available to manage these conditions. Alterations of cellular pro ...
