  • Publication number: 20080014596
    Abstract: Disclosed herein are methods for the quantification of ADDL binding to neuronal cells, including, but not limited to, primary cultures of hippocampal neurons. The method identifies and selects neurons based on any means capable of distinguishing neuronal cells, including, but not limited to, MAP2 immunoreactivity, which ensures that glial cells are excluded from an ADDL binding analysis; antibodies selective for neuronal cell surface receptors and/or other surface markers; reagents specific for neuronal signalling markers present intracellularly; and the like. Furthermore, ADDL binding occurs in a sub-population of 16 DIV neurons and is heterogeneous in intensity among individual cells. Also, ADDL binding can be further specified and quantified by using additional markers. Additionally, the presence or absence of ADDL binding is used to identify, characterize, analyze, assess, and/or evaluate agents (e.g.

  • Publication number: 20070264669
    Abstract: The present invention relates to methods for enhancing the cellular uptake and clearance of soluble oligomeric A? peptide assemblies from the environment surrounding both neuronal and non-neuronal cells. Oligomeric A? 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 A? peptide assemblies, also known as ADDLs, and ADDL-related assemblies.

  • Publication number: 20070218499
    Abstract: Disclosed herein are antibodies that bind with high specificity to soluble oligomers of amyloid ? (Abeta) and methods of employing those antibodies. The antibodies are able to distinguish between Alzheimer's Disease (AD) and control human brain extracts. The antibodies identify endogenous Abeta oligomers in AD brain slices and also bind to Abeta oligomers on cultured hippocampal cells. The antibodies neutralize endogenous Abeta oligomers and Abeta oligomers produced in solution.

  • Patent number: 5843634
    Abstract: This invention relates to genetically engineered enzymes, their ligand conjugates, their manufacture, and their use in qualitative or quantitative assays. A hybrid enzyme, such as an AP-epitope, has a foreign amino acid moiety (an epitope) inserted near the active site of the starting AP enzyme. The foreign amino acid moiety binds with an analyte, and, as a consequence of this binding, the enzymatic activity of the hybrid enzyme, AP-epitope, is modified. The changes in the enzymatic activity are dependent upon the presence, or the amount, of the analyte. In another embodiment, the hybrid enzyme consists of a cysteine introduced near the active site of an AP to give a hybrid enzyme. The cysteine on the hybrid enzyme serves as a point of conjugation of a ligand, such as theophylline, ferritin, thyroxine, or digoxigenin, to form the hybrid enzyme-ligand conjugate.
