    摘要: This invention relates to methods of diagnosing Alzheimer's disease and methods of screening for compounds for the treatment or prevention of Alzheimer's disease. The methods are based upon newly discovered differences in protein phosphatase 2A (PP2A) function and related molecular events in Alzheimer's disease cells compared to control cells. In one embodiment, differences in basal PP2A gene expression in Alzheimer's cells are compared to controls. In another embodiment differences in PP2A protein and enzyme activity are compared in test and control cells. In another embodiment differences in response to substances that inhibit PP2A function are compared. Still another embodiment detects differences in the subcellular distribution of phosphorylated Erk1/2, a substrate of PP2A, in normal and Alzheimer's disease cells. The detection of Alzheimer's disease-specific differences in PP2A function and related events in peripheral tissues provides the basis for highly practical and efficient tests and diagnostic test kits for the early diagnosis of Alzheimer's disease, as well as providing a biochemical basis for identifying therapeutic targets for drug development.

    摘要: The present invention relates to methods for enhancing the cellular uptake and clearance of soluble oligomeric Aβ peptide assemblies from the environment surrounding both neuronal and non-neuronal cells. Oligomeric Aβ peptide assembly uptake and clearance is achieved via an agent that enhances insulin receptor signaling. Such ADDL uptake enhancers represent effective anti-ADDL therapeutics for use in the therapeutic treatment and/or prophylactic treatment of diseases including Alzheimer's disease, Down's syndrome, and the like, in which compromised nerve cell function is linked to the formation and/or the activity of soluble oligomeric Aβ peptide assemblies, also known as ADDLs, and ADDL-related assemblies.

    摘要: The invention provides a method for modulating attentive cognition comprising administering a compound that alters intraneuronal carbonic anhydrase activity thereby affecting establishment of a theta rhythm. The metabolic pathway of the compound preferably involves bicarbonate-mediated GABAergic depolarization. The term “attentive cognition” is meant to encompass memory formation, learning, spatial memory, and attention. The modulating may be stimulating, or the compound may have the multiple effects of inhibiting intraneuronal carbonic anhydrase activity, establishment of a theta rhythm, and memory acquisition. The invention further provides a method of modulating memory and attention comprising switching theta rhythm on and off, the switching comprising potentiating or inhibiting intraneuronal carbonic anhydrase activity.
