    摘要: The invention relates to rapid methods for determining formation of A&bgr; amyloid and screening compounds which inhibit formation of A&bgr; amyloid in vitro, as well as kits for carrying out the present methods. Such an agent used in vivo may prevent, ameliorate or reverse the symptoms of Alzheimer's disease and A&bgr; amyloidotic disorders related to Alzheimer's disease, Down's syndrome, and Guamanian amyotrophic lateral sclerosis/Parkinson's dementia complex. The process described in this invention involves the rapid induction of A&bgr; amyloid by a heavy metal cation capable of binding to a polypeptide comprising at least amino acids 6 to 28 of A&bgr;, such as zinc to form amyloid and determination of formation of tinctorial A&bgr; amyloid. Moreover, a method of determining effectiveness of a candidate anti-amyloidotic agent for prevention or treatment of A&bgr; amyloidosis is described which uses cell cultures which express at least a human A&bgr; peptide.

    摘要: The disclosed invention relates to a diagnostic method for Alzheimer's disease based on genotyping the Alpha-2-Macroglobulin locus. A statistically significant correlation was found between inheritance of particular alleles of the Alpha-2-Macroglobulin gene and the occurrence of Alzheimer's disease. The diagnostic method involves the isolation of nucleic acid from an individual and subsequent genotyping by means such as sequencing or restriction fragment length polymorphism analysis. The invention also provides a means of genotype analysis through protein isotyping Alpha-2-Macroglobulin variant proteins. Finally, kits for nucleic acid analysis or protein analysis are taught.

    摘要: The present invention relates to novel uses for a family of small molecules, Differentiation-Inducing Factors (DIFs). It has been discovered that DIFs surprisingly can alter the metabolic processing of amyloid precursor protein (APP) and in turn reduce the level of secreted Aβ. The metabolic processing of other γ-secretase substrates normally present in cells (Notch and APLP1) is not affected when treated with DIF. The invention provides methods for reducing Aβ production in mammalian cells that express APP by administering DIF-I, DIF-2, DIF-3, a functionally equivalent analog and or any combination thereof. The invention also provides methods for treating and/or preventing Alzheimer's disease by preferentially reducing Aβ production.
