The accumulation of insoluble protein aggregates in intra and perinuclear inclusions is a hallmark of Huntington's disease (HD) and related glutamine-repeat disorders. A central question is whether protein aggregation plays a direct role in the pathogenesis of these neurodegenerative diseases.

The neurotoxicity of amyloid beta (Abeta) is widely believed to play a seminal role in neurodegeneration in Alzheimer's disease. We examined the effect of Chrysamine G (CG) on such neurotoxicity using the specific measurement of surviving neurons. CG was found

Extracellular senile plaques (SPs) are hallmark brain lesions of sporadic Alzheimer's disease (AD) and the likely consequence of genetic mutations that cause familial AD by increasing production of amyloidogenic amyloid-beta (Abeta). Although Abeta vaccines and inhibitors of amyloidogenic secretases are

This study describes the synthesis and in vitro testing of small molecule probes that may eventually prove useful as markers of amyloid deposition in living patients. The prototype agent, Chrysamine G (CG), is a derivative of Congo red. CG binds

Huntington's disease (HD) is a late onset neurodegenerative disorder caused by a CAG/polyglutamine (polyQ) repeat expansion. PolyQ aggregates can be detected in the nuclei and processes of neurons in HD patients and mouse models prior to the onset of symptoms.
