Abstract
(EN)
Anti-sense peptides that correspond to Amyloid-ß protein residues 1-43 are identified, and are used to identify protein binding sites on enzymes that interact with Amyloid-ß. The anti-sense peptides can be used as, or to identify, therapeutic agents that prevent Amyloid-ß cytotoxicity, and may be useful in the treatment of Alzheimer's disease. The anti-sense peptides show sequence similarity to the protein kinase cdc2, and it has now been found that the cytotoxic form of Aß is phosphorylated.

(FR)
Selon l'invention, des peptides antisens correspondant à des résidus de protéine ß-amyloïde 1-43 sont identifiés, et employés pour l'identification de sites de liaison de protéines sur des enzymes interagissant avec ß-amyloïde. Ces peptides antisens peuvent servir d'agents thérapeutiques, ou à l'identification d'agents thérapeutiques empêchant la cytotoxicité de ß-amyloïde, et éventuellement se révéler utiles dans le traitement de la maladie d'Alzheimer. Lesdits peptides présentent une similarité séquentielle avec la protéine kinase cdc2, la forme cytotoxique de ßA étant phosphorylée.
