The invention relates to antibodies and antigen-binding fragments that specifically bind to microtubule-associated protein tau. The invention also relates to diagnostic, prophylactic and therapeutic methods using anti-tau antibodies.

Provided are methods of mitigating, reversing or eliminating in a subject one or more symptoms associated with cognitive impairment associated with amyloid deposits in the brain (e.g., olfactory dysfunction as a risk factor of dementia, mild cognitive impairment, Alzheimer's Disease) by detecting and targeting gram negative bacteria in the brain.

Biomarkers and methods for identifying, verifying and confirming circulating serum-based microRNAs. The microRNAs (PARKmiRs) can be used to differentiate patient's suffering from Alzheimer's disease (AD) from non-AD patients.

The present disclosure relates to the use of PGC-1α expression to identify a subject that is conducive to treatment with a ma-485 inhibitor. In some aspects, the subject suffers from a disease or disorder associated with reduced PGC-1α expression. In some aspects, the PGC-1α expression is measured in the serum of the subject.

The present disclosure relates to the use of SIRT1 expression to identify a subject that is conducive to treatment with a miR-485 inhibitor. In some aspects, the subject suffers from a disease or disorder associated with reduced SIRT1 expression. In some aspects, the SIRT1 expression is measured in the serum of the subject.

An in vitro method for diagnosing Alzheimer's disease (AD) includes determining the content of mercaptoalbumin (HMA) in a sample of cerebrospinal fluid (CSF), and comparing the content determined with the content of HMA in CSF in healthy subjects. If the HMA content is less than that of the healthy subjects, it is indicative of AD.

The present disclosure provides treatments for neurodegenerative disorders and more particularly to methods for treatment of patients with Multiple Sclerosis (MS), Amyotrophic Lateral Sclerosis (ALS), or Alzheimer's disease of different degrees of severity. The methods for treatment of patients who have suffered neurodegenerative diseases and specifically MS, ALS, or Alzheimer's disease includes administering a xenon gas mixture in subjects with elevated levels of neurodegenerative microglia (MGnD), e.g., determined based on levels of inflammatory biomarkers, measured in blood, serum and CSF, or levels of CLEC7A (Dectin-1)/Translocator Protein (TSPO) expression, e.g., measured using TSPO imaging.

In some embodiments herein, methods, compositions, and uses for modulating lymphatic vessels of the central nervous system are described. In some embodiments, methods, compositions, or uses for treating, preventing, or ameliorating symptoms of a neurological disease comprise increasing flow via meningeal lymphatic vessels are described.

The present invention provides genetic markers associated with the Alzheimer's Disease (AD), diagnostic and treatment methods for AD, and kits for diagnosing AD.

The present invention relates to a composition for preventing or treating Alzheimer’s disease, comprising a phospholipase C (PLC) activator as an active ingredient. A composition comprising the PLC activator of the present invention as an active ingredient restores the S-eCB mobilization suppressed by AβO, recovers the synaptic plasticity impaired by AβO, and not only recovers PLCβ1 protein levels to normal levels in AβO-treated mouse hippocampal slices and 5XFAD mouse hippocampal slices in the chronic stage of AD, but also recovers contextual fear memory impairment in AD mice, and thus is expected to be usefully used for preventing or treating Alzheimer’s disease.
