AMYLOID BETA PEPTIDES, ASSEMBLIES THEREOF, AND RELATED METHODS
The present invention provides amyloid β peptide assemblies composed of at least three amyloid β peptide subunits, wherein at least one of the amyloid β peptide subunits is an amyloid β peptide analog. The invention further relates to metal complexes of amyloid β peptide assemblies and the use of amyloid β peptide assemblies as vaccines and in the identification of agents that modulate assembly of the amyloid β peptide subunits.
1 . An amyloid beta peptide having the amino acid sequence Asp-Ala-Glu-Phe-Arg-His-Asp-Ser-Gly-Tyr-Glu-Val-His-His-Gln-Lys-Leu-Val-Phe-Phe-Ala-Glu-Asp-Val-Gly-Ser-Asn-Lys-Gly-Ala-Ile-Ile-Gly-Leu-Nle-Val-(D)Pro-Gly-Val-Val-Ile-Ala (SEQ ID NO:41).
2 . A composition comprising the amyloid beta peptide of claim 1 in admixture with an adjuvant.
3 . An isolated antibody that specifically binds to the amyloid beta peptide of claim 1 .
