Abstract

From Yeast to Therapeutic? Yeast has shown some promise as a model system to generate lead compounds that could have therapeutic potential for the cellular problems associated with neurodegenerative diseases. Along these lines, Tardiff et al. (p. 979 , published online 24 October) and Chung et al. (p. 983 , published online 24 October) describe the results of multiple screens in yeast that lead to the identification of a potential therapeutic compound to combat the cytotoxic affect of α-synuclein accumulation. The compound was able to reverse the pathological hallmarks of Parkinson's disease in cultured neurons derived from patients with α-synuclein–induced Parkinson's disease dementia.
