An integrative approach to elucidate the mechanisms and dynamics of Huntingtin aggregation and inclusion formation in neuronal models of Huntington's Disease

Despite the fact that the gene responsible for Huntington's disease (HD) is known, we still do not understand the underlying mechanisms leading to neurodegeneration and death. Identifying and understanding the mechanisms controlling mutant huntingtin (mHtt ...

N-terminal mutant huntingtin deposition correlates with CAG repeat length and symptom onset, but not neuronal loss in Huntington's disease

Hilal Lashuel, Lorène Aeschbach, Nathan Alain Denis Riguet

Huntington's disease (HD) is caused by a CAG repeat expansion mutation in the gene encoding the huntingtin (Htt) protein, with mutant Htt protein subsequently forming aggregates within the brain. Mutant Htt is a current target for novel therapeutic strateg ...

Nuclear and cytoplasmic huntingtin inclusions exhibit distinct biochemical composition, interactome and ultrastructural properties

Hilal Lashuel, Graham Knott, Anne-Laure Mahul Mellier, Mary-Claude Croisier-Coeytaux, Johannes Burtscher, Nathan Alain Denis Riguet, Niran Maharjan

Despite the strong evidence linking the aggregation of the Huntingtin protein (Htt) to the pathogenesis of Huntington’s disease (HD), the mechanisms underlying Htt aggregation and neurodegeneration remain poorly understood. Herein, we investigated the ultr ...

Monitoring alpha-synuclein oligomerization and aggregation using bimolecular fluorescence complementation assays: What you see is not always what you get

Hilal Lashuel, Nathan Alain Denis Riguet, Bryan Frey, Abdelrahman Mohammed Adel Elsaeed Mansour AlOkda

Bimolecular fluorescence complementation (BiFC) was introduced a decade ago as a method to monitor alpha-synuclein (alpha-syn) oligomerization in intact cells. Since then, several alpha-syn BiFC cellular assays and animal models have been developed based o ...

The Nt17 Domain and its Helical Conformation Regulate the Aggregation, Cellular Properties and Neurotoxicity of Mutant Huntingtin Exon 1

Giovanni Dietler, Hilal Lashuel, Anne-Laure Mahul Mellier, Francesco Simone Ruggeri, Anass Chiki, Sean Michael Deguire, Urszula Beata Cendrowska, Sophie Vieweg, Nathan Alain Denis Riguet

Converging evidence points to the N-terminal domain comprising the first 17 amino acids of the Huntingtin protein (Nt17) as a key regulator of its aggregation, cellular properties and toxicity. In this study, we further investigated the interplay between N ...
