TREATMENTS FOR NEUROTOXICITY IN ALZHEIMER'S DISEASE BY beta-AMYLOID PEPTIDES

摘要

The invention involves identification of a mechanism of β-amyloid peptide cytotoxicity, which enables treatment of conditions caused by β-amyloid peptide aggregates by administration of compounds which antagonize the mechanism of cytoxicity. The invention includes the identification and isolation of compounds which can antagonize the aggregation of β-amyloid peptides and the neurotoxic effects of such aggregates. The compounds include isolated peptides which were selected for their ability to form a complex with a β-amyloid peptide, or are derived from peptides so selected. Methods for treating conditions resulting from neurotoxic β-amyloid peptide aggregates and pharmaceutical preparations are provided. Also provided are methods for selecting additional compounds which can antagonize the aggregation of β-amyloid peptides and the neurotoxic effects of such aggregates.
