    摘要: This invention provides methods useful in aiding in the diagnosis of Alzheimer's disease. The methods involve measuring the amount of amyloid-β peptide (x−≧41) in the cerebrospinal fluid of a patient. High levels of the peptide generally are inconsistent with a diagnosis of Alzheimer's. Low levels of the peptide are consistent with the disease and, with other tests, can provide a positive diagnosis. Other methods involve measuring the amounts of both Aβ(x−≧41) and tau. Low levels of Aβ(x−≧41) and high levels of tau are a positive indicator of Alzheimer's disease, while high levels of Aβ(x−≧41) and low levels of tau are a negative indication of Alzheimer's disease.

    摘要: The construction of transgenic animal models of human Alzheimer's disease, and methods of using the models to screen potential Alzhe## disease therapeutics, are described. The models are characterized by pathologies similar to pathologies observed in Alzheimer's disease, based on expression of all three forms of the β-amyloid precursor protein (APP), APP695, APP751, and APP770, as well as various point mutations based on naturally occurring mutations, such as the London and Indiana familial Alzheimer's disease (FAD) mutations at amino acid 717, predicted mutations in the APP gene, and truncated forms of APP that contain the Aβ region. Animal cells can be isolated from the transgenic animals or prepared using the same constructs with standard techniques such as lipofection or electroporation. The transgenic animals, or animal cells, are used to screen for compounds altering the pathological course of Alzheimer's disease as measured by their effect on the amount of APP, β-amyloid peptide, and numerous other Alzheimer's disease markers in the animals, the neuropathology of the animals, as well as by behavioral alterations in the animals.

    摘要: Soluble .beta.-amyloid peptide (.beta.AP) is measured in biological fluids at very low concentrations, typically in the range from 0.1 ng/ml to 10 ng/ml. The measurement of .beta.AP concentrations in animals or conditioned medium from cultured cells can be used for drug screening, where test compounds are administered to the animals or exposed to the cultured cells and the accumulation of .beta.AP in the animal or culture medium observed. It has been found that elevated levels of .beta.AP in body fluids, such as blood and cerebrospinal fluid, is associated with the presence of a .beta.AP-related condition in a patient, such as Alzheimer's Disease. Methods for diagnosing and monitoring .beta.AP-related conditions comprise measuring the levels of .beta.AP in such body fluids from a patient.
