Solution structure of polyglutamine tracts in GST‐polyglutamine fusion proteins
Aggregation of expanded polyglutamine (polyQ) seems to be the cause of various genetic neurodegenerative diseases. Relatively little is known as yet about the polyQ structure and the mechanism that induces aggregation. We have characterised the solution structure of polyQ in a proteic context using a model system based on glutathione S‐transferase ...

Emerging evidence has implicated non-neuronal cells, particularly oligodendrocytes, in the pathophysiology of many neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis, Huntington’s disease and ...

Microsatellites are repetitive sequences commonly found in the genomes of higher organisms. These repetitive sequences are prone to expansion or contraction, and when microsatellite expansion occurs in the regulatory or coding regions of genes this can ...

Are Polyglutamine Diseases Expanding? [PDF]
It remains a matter of speculation as to whether the sense CUG-containing RNA and/or the antisense CAG-encoding polyglutamine peptide serves as the pathogenic moiety in Huntington's disease like-2 (HDL2). In this issue of Neuron, Wilburn et al. show that in a HDL2 mouse model, the polyglutamine peptide drives disease progression.

Activation of p38MAPK contributes to expanded polyglutamine-induced cytotoxicity.
BackgroundThe signaling pathways that may modulate the pathogenesis of diseases induced by expanded polyglutamine proteins are not well understood.Methodologies/principal findingsHerein we demonstrate that expanded polyglutamine protein cytotoxicity is ...

Autophagy and polyglutamine diseases
In polyglutamine diseases, an abnormally elongated polyglutamine tract results in protein misfolding and accumulation of intracellular aggregates. The length of the polyglutamine expansion correlates with the tendency of the mutant protein to aggregate, as well as with neuronal toxicity and earlier disease onset.

d-Polyglutamine Amyloid Recruits l-Polyglutamine Monomers and Kills Cells [PDF]
Polyglutamine (polyQ) amyloid fibrils are observed in disease tissue and have been implicated as toxic agents responsible for neurodegeneration in expanded CAG repeat diseases such as Huntington's disease. Despite intensive efforts, the mechanism of amyloid toxicity remains unknown. As a novel approach to probing polyQ toxicity, we investigate here how

Huntington’s disease is a progressive neurodegenerative disease, caused by a polyglutamine expansion in the huntingtin protein. A prominent hallmark of the disease is the presence of intracellular aggregates initiated by N-terminal huntingtin fragments ...
