The 42 amino acid Alzheimer's Aβ peptide is involved in the progression of Alzheimer's disease. Here we describe the effects of intracellular Aβ, produced through its attachment to either end of a green fluorescent protein, in yeast. Cells producing Aβ exhibited a lower growth yield and a heat shock response, showing that Aβ fusions promote stress in cells and supporting the notion that intracellular Aβ is a toxic molecule. These studies have relevance in understanding the role of Aβ in the death of neuronal cells, and indicate that yeast may be a new tractable model system for the screening for inhibitors of the stress caused by Aβ.
