NEW TAU SPECIES

The invention relates to the identification of a new Tau species starting at residue Met11 (Met11-Tau) which is N-alpha-terminally acetylated form (N-alpha-acetyl-Met11-Tau species: Ac-Met11-Tau). Several monoclonal antibodies specific of this new Tau species have been developed. One of this antibody, 2H2/D11, was used in THY-Tau22 mouse model (that develops with age neurofibrillary degeneration (NFD) and memory deficits), and N-alpha-Ac-Met11-Tau species were clearly detected early in neurons displaying NFD on hippocampal brain sections while it is not reactive in hippocampus from elderly controls. Finally, by using ELISA sandwich specific of Ac-Met11-Tau species, Alzheimer Disease (AD) brain samples are clearly discriminated from human elderly control brains. Thus the invention relates to this new Tau species starting from the methionine residue at position 11 said methionine being N-alpha acetylated. The invention also relates to antibody that specifically binds this new tau species, a method of detection of this new Tau species and a method of diagnosis of Tauopathy disorder.

The NXNL2 gene encodes by alternative splicing for a trophic factor RdCVF2 that enhances the function and the survival of neurons involved in long term memory. Now the inventors demonstrated that the cell surface receptor for the trophic factor RdCVF2 is NPTN65. The set-up of methods that could be used to screen for small molecules, agonists of RdCVF2 signaling in the brain would be suitable for the development of a future metabolic and redox treatment of tauopathies and in particular Alzheimer's disease.

A COMPOUND FOR THE DETERMINATION OF THE PROTEIN FKBP12 AND A SENSOR UNIT COMPRISING IT

The present invention relates to novel compounds useful as sensors for the rapid and specific determination of the FKBP12 protein, a peptidyl-prolyl cis-trans isomerase (PPlase), the levels of which in the biological fluids of a subject change if the subject is affected by pathological conditions, in particular neurodegenerative diseases, such as the Parkinson's disease and the Alzheimer's syndrome, tumour pathologies, autoimmune diseases, or if that subject is in a phase of acute rejection after organ transplantation.

Novel Molecules for Diagnosis
20230034474 · 2023-02-02 ·

The present invention relates to novel amyloid-beta (abeta) binding molecules, in particular to abeta antibodies or antigen-binding fragments thereof and/or uses thereof. The provided molecules can also be used for determining a predisposition to amyloid-beta associated diseases, disorders or conditions, monitoring residual disorder of a disease or condition, or predicting the responsiveness of a patient who is suffering from such disease or condition to the treatment with a certain medicament. Thus, the invention relates to novel molecules that can be employed for the diagnosis of diseases, disorders or conditions associated with amyloid-beta. A sandwich immunoassay may be based on capture and detection amyloid-beta binding antibodies or antigen-binding fragments thereof in which one or other of the capture or detection antibody or antigen-binding fragment thereof displays no cross-reactivity to soluble amyloid precursor protein (APP). The other amyloid-beta binding antibody or antigen-binding fragment my display cross-reactivity to soluble amyloid precursor protein (APP) without compromising the specificity of the assay against soluble APP.

The present invention addresses a problem of providing a method for collecting extracellular vesicles derived from nervous system cells at an improved efficiency.

This problem is solved by a method for collecting extracellular vesicles derived from nervous system cells, said method comprising a step for mixing an anti-APLP1 antibody with a sample containing extracellular vesicles to form anti-APLP1 antibody-extracellular vesicle complexes and a step for collecting the anti-APLP1 antibody-extracellular vesicle complexes.

Targeting ligands for tau pathology

Methods and compositions for detecting tau pathology are described. The compositions for detecting tau pathology comprise a targeting ligand that specifically binds to a cell surface marker of tau pathology, wherein the targeting ligand is linked to a liposome that includes an imaging agent. The compositions can be used in a method for imaging tau pathology in a subject that comprises administering to the subject an effective amount of the composition to a subject and imaging at least a portion of the subject to determine if that portion of the subject exhibits tau pathology. The compositions can also be used to detect tau pathology in biological samples obtained from a subject.
