General description

Huntington’s disease (HD) belongs to a family of polyglutamine diseases, which includes dentatorubralpallidoluysian atrophy (DRPLA), spinobulbar muscular atrophy (SBMA) and spinocerebellar ataxia (SCA) types 1–3, 6, 7 and 17. In these diseases, the non-pathogenic alleles contain fewer than approximately 35 consecutive glutamine repeats and encode a normal polyglutamine domain. In contrast, the pathogenic alleles usually contain 39 or more consecutive glutamine repeats. Higher repeat numbers lead to lower ages of onset. Patients with 40-60 glutamine repeats normally develop disease as adults, whereas patients with more than 60 repeats develop a juvenile onset disease. Each polyglutamine expansion disorder displays characteristic pathology, with neuronal loss evident in specific regions of the brain. HD results from expansions of a glutamine tract in a large cystolic protein known as huntingtin.

Specificity

The epitope of MAB1574 was found to be a homopolymeric glutamine stretch. The original immunogen was the general transcription factor TATA Box-binding protein (TBP) which contains a 38-glns stretch (Lescure et al). Other polyglutamine-containing proteins are recognized by the MAB1574, notably those involved in several human neurodegenerative diseases caused by a CAG repeat expansion, like Huntington′s disease and spinocerebellar ataxia type 2, 3 and 7 (Trottier et al., 1995). Importantly, for proteins involved in these neurodegenerative disorders, MAB1574 showed remarkable property of detecting much better the pathological proteins that contain a polyglutamine expansion (37 glns) than the wild type proteins (Trottier et al., 1995). MAB1574 has been used to identify new neurodegenerative diseases caused by polyglutamine expansion and to help for cloning of the corresponding affected genes (Trottier 1995-1998; Imbert 1996; Stevanin 1996). MAB1574 is also able to detect intracellular inclusions, which is a hallmark of such diseases (Paulson, 1997).

Identifying molecular drivers of pathology provides potential therapeutic targets. Differentiating between drivers and coincidental molecular alterations presents a major challenge. Variation unrelated to pathology further complicates transcriptomic, proteomic and metabolomic studies which measure large numbers of individual molecules. To overcome
