| Background Information | Huntington disease (HD) is a neurodegenerative disorder caused by an expansion of a polyglutamine (PolyQ) domain in the protein huntingtin (htt) that leads to its aggregation into fibrils. PolyQ expansion above 35 -40 results in disease associated with htt aggregation into inclusion bodies. These expanded PolyQ repeats adopt multiple potentially toxic conformations increase atrophin-1 and huntingtin levels and abnormally sequester proteins that are essential for transcription. PolyQ domains of different lengths can display different conformations. The primary sites of neuropathology show variations between different PolyQ disorders, but usually include the cerebellum, striatum, cerebral cortex, brainstem, spinal cord, and thalamus. Huntington s disease (HD) and dentatorubral pallidoluysian atrophy (DRPLA) display clinical similarities, but exhibit different regional pathologies. For example, in HD striatum is the most affected region whereas in DRPLA dentate nucleus of the cerebellum is more severely affected. Clone MW1 strongly binds to the expanded PolyQ of mutant Htt, but does not display any detectible binding to normal human or wild-type murine Htt. The clone MW1, which bind to the polyQ repeat in htt is reported to increase htt-induced toxicity and aggregation. (The clone MW1, which bind to the polyQ repeat in htt is reported to increased htt-induced toxicity and aggregation. (Ref.: Luthi-Carter, R et Al. (2012). Hum. Mol.
