摘要： Disclosed herein are antibodies that bind with high specificity to soluble oligomers of amyloid β (Abeta) and methods utilizing such 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.

摘要： Disclosed and claimed herein are compositions comprising ADDL receptors, related compositions, and related methods. ADDL receptors are typically, but perhaps not exclusively, localized at the post-synaptic density (PSD) of neuronal cells. Related compositions include, but are not limited to, compounds that affect, positively or negatively, ADDL binding to neuronal cells, either via one or more receptors localized at the post-synaptic density (PSD) or otherwise. Related methods include, but are not limited to, procedures to screen for compounds that affect, either positively or negatively, ADDL binding to neuronal cells, either via one or more receptors localized at the post-synaptic density (PSD) or otherwise. Other related methods include, but are not limited to, prevention and treatment of ADDL-related diseases, such as Alzheimer’s disease, mild cognitive impairment, Down’s syndrome, and the like, using compositions that inhibit, block, or otherwise interfere with ADDL binding to one or more receptors localized at the post-synaptic density of neuronal cells.

摘要： The invention herein comprises amyloid beta-derived diffusible ligands (ADDLs), compositions comprising ADDLs, ADDL-surrogates, ADDL-binding molecules, and methods of using any of the foregoing compounds and compositions. ADDLs comprise amyloid β protein assembled into soluble, globular, non-fibrillar, oligomeric structures capable of activating specific cellular processes. The invention also comprises methods of generating ADDL-specific antibodies and methods of using ADDL-specific antibodies for assaying the formation, presence, receptor protein binding and cellular activity of ADDLs, as well as using such antibodies to detect compounds that block the formation or activity of ADDLs, and methods of identifying such compounds. The invention further provides methods of using ADDL-specifc antibodies in modulating ADDL formation and/or activity, inter alia in the treatment of learning and/or memory disorders.
