Provided are novel specific binding molecules, particularly human antibodies as well as fragments, derivatives and variants thereof that recognize neoepitopes of disease-associated proteins which derive from native endogenous proteins but are prevalent in the body of a patient in a variant form and/or out of their normal physiological context. In addition, pharmaceutical compositions comprising such binding molecules, antibodies and mimics thereof and methods of screening for novel binding molecules, which may or may not be antibodies as well as targets in the treatment of neurological disorders such as Alzheimer's disease are described.

An apparatus for performing cerebral micro-dialysis to treat neurological disease of a patient's brain includes a catheter for implantation in or near the patient's brain, an implantable pump communicated with the catheter to transport cerebrospinal fluid (CSF) from the patient, which CSF contains diseased cells or biomolecules associated with the neurological disease, and an implantable separation device communicated with the pump wherein the diseased cells or biomolecules are removed, where the separation apparatus includes a dialysis membrane impregnated with an antibody, a reversible electrostatic filter, and/or a magnetic field effect fractionation chamber wherein a magnetically-tagged antibody scavenges and aids in the removal of circulating diseased cells or biomolecules from the CSF.

Current application relates to the field of neurodegenerative diseases. More specifically, the present invention relates to screening methods to identify compounds that can reduce the production of amyloidogenic Amyloid beta fragments. Said compounds can be used in treatments of for example Alzheimer's disease.

The present disclosure relates generally to the field of neurology. In particular, the disclosure relates to a method of detecting a neurodegenerative disease in a subject and methods of treatment thereof. The methods include detecting the level of an exosome-bound aggregated biomarker in a sample obtained from the subject, wherein an increased level of the exosome-bound aggregated biomarker as compared to a reference indicates that the subject is suffering from a neurodegenerative disease. Also described are methods for detecting a subject at risk of developing amyloidosis or a neurodegenerative disease, methods for detecting and treating amyloidosis or a neurodegenerative disease in a subject, and methods of determining the aggregation state of a biomarker in a sample.

The present disclosure relates generally to a sensor chip and methods for the detection of an analyte. In particular, the disclosure relates to a sensor chip for detecting an analyte in a subject suffering from a neurodegenerative disease. The sensor chip comprises a conductive layer on a membrane support layer, wherein a plurality of apertures extend through the conductive layer and the membrane support layer and are arranged such that illumination of the conductive layer and/or the membrane support layer produces a surface plasmon resonance.

Provided herein are methods and compositions for determining whether a patient suffers from a neurological disease or disorder is provided, comprising detecting the presence of a phosphorylated tau protein in a tissue of the patient, wherein the detecting comprises contacting the phosphorylated tau protein with a compound described herein.

The invention provides antibodies that specifically bind tau. The antibodies inhibit or delay tau-associated pathologies and associated symptomatic deterioration.

A test strip for detecting Aβ in urine includes a polyvinyl chloride (PVC) bottom plate. The PVC bottom plate is laid with a sample pad, a conjugation pad, a chromatography pad, and an absorbent pad that are overlapped in sequence. The conjugation pad is coated with colloidal gold particles conjugated to a monoclonal antibody. The chromatography pad is provided with a test line on the side proximate to the conjugation pad, and is provided with a control line on the side proximate to the absorbent pad. The test line is coated with an Aβ-binding polymer. The control line is coated with a goat anti-mouse IgG polyclonal antibody. The method is suitable for the following: routine clinical pathological examination; general screening of a large number of people and self-screening of home end-users; assisting the early diagnosis and prejudgment of mild cognitive impairment (MCI) clinically.

The present invention relates to the development of polypeptides useful for the treatment of diseases associated with amyloid deposits, and more specifically for the treatment of Alzheimer's disease. The invention also relates to compositions comprising the developed polypeptides and to a method for the identification of compounds useful for the treatment of diseases associated with the formation of amyloid deposits.

A production method for a cerebral organoid having amyloid plaques is provided, the method including a step (a) of forming, in the presence of a SMAD inhibitor, an embryoid body from a pluripotent stem cell having a mutation in an Alzheimer's disease-related gene; a step (b) of embedding the embryoid body after the step (a) in an extracellular matrix and three-dimensionally culturing the embedded embryoid body in the presence of a SMAD inhibitor and a glycogen synthase kinase 3β (GSK3β) inhibitor to form an organoid; and a step (c) of removing the organoid after the step (b) from the extracellular matrix and subjecting the removed organoid to stirring culture in a medium, where at least a part of the step (c) is carried out in the presence of leukemia inhibitory factor (LIF).
