Forms and Phases in Huntingtin Protein Aggregation [PDF]
Using a combination of fluorescence microscopy and electron tomography, Peskett et al. (2018), in this issue of Molecular Cell, explore the nucleation of amyloid-like filaments from liquid-like condensates of huntingtin protein exon1 with disease-related polyQ extensions.

The mechanisms underlying Huntingtin protein (Htt) aggregation are not fully understood. Here the authors perform a detailed investigation of the ultrastructural and biochemical properties of huntingtin cytoplasmic and nuclear inclusions, and reveal that

Cardiac dysfunction in the R6/2 mouse model of Huntington’s disease
Recent evidence suggests that mutant huntingtin protein-induced energetic perturbations contribute to neuronal dysfunction in Huntington’s disease (HD). Given the ubiquitous expression of huntingtin, other cell types with high energetic burden may be at ...

DISC1 and Huntington's disease--overlapping pathways of vulnerability to neurological disorder? [PDF]
We re-annotated the interacting partners of the neuronal scaffold protein DISC1 using a knowledge-based approach that incorporated recent protein interaction data and published literature to. This revealed two highly connected networks.

Depletion of CBP is directly linked with cellular toxicity caused by mutant huntingtin
Huntington's disease is a neurodegenerative disease caused by an expanded polyglutamine stretch within the huntingtin protein. Transfection of mutant huntingtin causes cell toxicity and depletion of CREB binding protein (CBP) or its recruitment into ...

Huntington disease: Advances in the understanding of its mechanisms
Huntington disease (HD) is a devastating monogenic autosomal dominant disorder. HD is caused by a CAG expansion in exon 1 of the gene coding for huntingtin, placed in the short arm of chromosome 4.

Herein we report a boron‐based pyrazole, (Borsantrazole ‐ a small molecule that selectively targets oxidative stress) that significantly increases survival, reduces weight loss, delays disease onset, and affects global protein changes in the SOD1‐G37R mouse model of ALS.

Huntington's disease, with its dominant loss of striatal neurons, is triggered by an expanded glutamine tract in huntingtin. To investigate a proposed role for increased activation of the apoptotic cascade in mutant huntingtin's trigger mechanism, we ...

Structural Polymorphism of polyG Inclusions Revealed by In Situ Cryo‐Electron Tomography
Correlative cryo‐electron tomography in primary cortical neurons and NIID mouse brain tissue reveals that polyG inclusions are interconnected ribbon‐like assemblies rather than canonical amyloid fibrils. Multiple compartment‐specific ribbon states show distinct 26S proteasome accessibility, while cytoplasmic ribbons contact and deform ER‐like ...

Huntingtin interacts with a family of WW domain proteins [PDF]
The hallmark neuropathology of Huntington's disease (HD) is due to elongation of a polyglutamine segment in huntingtin, a novel approximately 350 kDa protein of unknown function. We used a yeast two-hybrid interactor screen to identify proteins whose association with huntingtin might be altered in the pathogenic process.
