Abstract: A soluble derivative of low-density lipoprotein receptor related protein-1 (sLRP-1) binds directly to Alzheimer's amyloid-? peptide (A?). This binding may be used to detect A? or to separate A? from the rest of a subject's body. In Alzheimer's disease, it may be used to provide diagnostic results by detecting A?, treatment by removing A?, or both.

Abstract: The present invention provides methods and compositions for screening, diagnosis and prognosis of Alzheimer's disease, for monitoring the effectiveness of Alzheimer's disease treatment, and for drug development.

Abstract: Model systems of Alzheimer's disease comprise a DNA sequence encoding an amyloid precursor protein (APP) isoform or fragment that has an amino acid substitution. The substituted amino acid may be other than valine at the amino acid position corresponding to amino acid residue position 717 of APP770. Methods of determining genetic predisposition to Alzheimer's disease are also disclosed.

Abstract: The present invention relates to immunogenic compositions and peptides comprising residues 4-10 (FRHDSGY) of the amyloid peptide Abeta42. The invention further relates to antibodies that bind to the Abeta(4-10) antigenic determinant.

Abstract: The present invention provides materials and methods for treating Alzheimer's disease and other tau related neurodegenerative disorders. A tau kinase, Brain Derived Tau Kinase (BDTK) is provided. BDTK can cause hyperphosphorylation of tau protein, which leads to formation of neurofibrillary tangles, which are implicated in the degenerative symptoms of Alzheimer's and other neurodegenerative disorders. Methods of diagnosis and treatment based on the discovery of this novel tau kinase are also provided.

Abstract: Transgenic cell and animal models for Alzheimer's disease are described. Cells of the animals and the cell models themselves comprise a recombinant DNA construct comprising a control sequence and, under the control of the control sequence, a DNA sequence encoding a kinase that is capable, directly or indirectly, of modulating the phosphorylation of the microtubule-forming protein tau. The transgenic cells and animals may be used for testing potential therapeutic agents for Alzheimer's disease.

Abstract: A method of screening pharmaceutical drugs, gene therapies, vaccines, dietary supplements, behavioral and environmental therapies and other clinical treatments for potential efficacy in the treatment of Alzheimer's disease in humans. The method includes selecting transgenic mice that are genetically altered for Alzheimer's disease and using measurement and/or imaging techniques to determine the activity level of the posterior cingulate region of the brains of the mice after treatment. Based on these measurements and comparisons to a control group, the effectiveness of the treatment in arresting or reversing Alzheimer's disease in mice can be determined, and the treatment can be identified as a promising candidate for human trials.

Abstract: Tryptamine, a normal constituent of the diet and an inhibitor of tryptophanyl-tRNA synthetase (TrpRS), induces formation of Alzheimer's disease characteristics as extracellular senile plaques and neurofibrillary tangles containing paired helical neurofilaments and/or straight neurofilaments in human differentiated neuronal cells. The effect of tryptamine on neuronal cells is dose-dependent and multi-staged resulting in differentiation and subsequently axon growth, followed by neurodegeneration. TrpRS was found normally in the neuronal body, axons and dendrites, whereas tryptamine induces it in the cytoskeleton. In tryptamine-treated cells, TrpRS co-localized with abnormally phosphorylated tau in neurofibrillary tangles and with &bgr;-amyloid in senile plaque-like formations. Moreover, TrpRS was detected in neurofibrillary tangles and congophilic senile plaques in Alzheimer's disease brain sections and brain sections of model mice following tryptamine treatment.
