A novel constrained peptide epitope derived from Aβ, related antibody compositions and methods of use. An isolated antibody that specifically binds to a cyclic peptide comprising the conformational epitope corresponding to a solvent-exposed, antibody accessible knuckle region of oligomeric Aβ is described. An antigenic peptide comprising an epitope having a constrained cyclic configuration, corresponding to a solvent-exposed, antibody accessible knuckle region of oligomeric Aβ is also described. Methods of treating, preventing, and diagnosing Alzheimer's disease are also described.

The invention relates to a highly sensitive method for the detection of pGlu-Abeta (pGlu-Aβ) peptides and the use of this method in the diagnosis of neurodegenerative diseases, such as Alzheimer's disease and Mild Cognitive Impairment. The invention further concerns a novel method for monitoring the effectiveness of a treatment of neurode-generative diseases by monitoring changes in the level of pGlu-Aβ peptides.

Disclosed is a method for identifying inhibitors of the interaction of CD36 receptor and amyloid-beta protein (Aβ), which consists in: immobilizing CD36 on a polystyrene plate; and detecting by colorimetric, the interaction thereof with fibrillar Aβ (fAβ), using a polyclonal anti-Aβ antibody and a secondary antibody conjugated to horseradish peroxidase (HRP). The inhibitors identified are potential agents for the treatment of Alzheimer's disease.

The invention relates to isolated recombinant peptides comprising an epitope from human tau 2N4R. The invention also relates to use of such peptides to generate binding molecules, such as antibodies, specific for the tau epitope and to such peptides and antibodies for use in investigation, diagnosis and treatment of tauopathies, such as Alzheimer’s disease.

Biomarkers useful for diagnosing and assessing inflammatory disease are provided, along with kits for measuring their expression. The invention also provides predictive models, based on the biomarkers, as well as computer systems, and software embodiments of the models for scoring and optionally classifying samples. The biomarkers include at least two biomarkers selected from the DAIMRK group and the score is a disease activity index (DAI).

The present invention relates to methods of treating neurodegenerative disorders associated with Alzheimer's disease (AD), Parkinson's disease (PD) and synucleinopathies, such as dementia with Lewy bodies, Down Syndrome (DS) and associated cognitive disorders, multiple system atrophy, and rare neuroaxonal dystrophies, such as Niemann-Pick type C disease (NPC) and Gaucher's disease comprising administering an inhibitor to disrupt the interaction between Aβ or αS and neuronal lipids. The invention further relates to assays for identifying agents that reduce interaction between Aβ or αS and neuronal lipids. Lastly, the invention relates to methods and compositions for intranasal administration of fatty acids or lipids containing fatty acid acyl chains of dietary lipids for promoting central nervous system health and/or prevention or treatment of neurodegenerative disorders.

The present subject matter relates to a non-invasive optical imaging method for monitoring early pathological events specific to Alzheimer's disease (AD), such as the development, amount and location of amyloid plaques. The ability to monitor such events provides a basis for, among other things, AD diagnosis, prognosis and assessment of potential therapies. In addition, the present subject matter introduces novel methods for treating AD and retinal ailments associated with AD. Aβ-plaque detection in living brains is extremely limited, especially at high resolution; therefore the present invention is based on studies focusing on the eyes as an alternative to brain-derived tissue that can be imaged directly, repetitively and non-invasively.

Aspects of the present disclosure include amyloid β (Aβ) peptides. In certain aspects, the Aβ peptides include a chiral substitution at an electrostatic cluster amino acid residue. Also provided are compositions, non-human animals, and kits that include the Aβ peptides. Methods involving the Aβ peptides are also provided.

The invention provides an antibody or antigen binding fragments thereof that binds to 3pE Aβ and methods of making and using the antibody or antigen binding fragment thereof, including use for formulations, administration and kits. The antibody and antigen binding fragments thereof and methods disclosed are useful for diagnosis, prognosis and treatment of Alzheimer's disease or other β-amyloid-related diseases.

The present disclosure provides methods of determining A-beta in a mammal before and after treatment of an amyloid disorder, comprising obtaining a first blood sample from the mammal; administering to the mammal a treatment for an amyloid disorder; obtaining a second blood sample from the mammal; quantifying a level of A-beta in the first blood sample and in the second blood sample; and determining the level of A-beta in the mammal before and after treatment of the amyloid disorder.
