    DESCRIPTION

    Alzheimer's disease (AD) is a common form of dementia characterized by the formation of extracellular senile plaques composed of aggregated amyloid peptide (Aβ). The present studies provide evidence that: cell resistance to amyloid toxicity is related to lipid raft cholesterol content. Cholesterol and GM1, affect the susceptibility of Familial Alzheimer's Disease (FAD) broblasts to A 42 oligomers in opposite ways, by modulating amyloid binding to lipid rafts and its subsequent toxic effects. The degree of toxicity of the oligomeric species results from a complex interplay between the structural and physicochemical features of both the oligomers and the cellular membrane. Neuronal differentiation of human mesenchymal stromal cells increases their resistance to A 42 aggregate toxicity. [Publisher's Text]
