Peptide fingerprinting of Alzheimer's disease in cerebrospinal fluid: identification and prospective evaluation of new synaptic biomarkers [PDF]

, 2011
<p><b>Background:</b> Today, dementias are diagnosed late in the course of disease. Future treatments have to start earlier in the disease process to avoid disability requiring new diagnostic tools.

Cerebrospinal fluid proteome profiling across the Alzheimer’s disease continuum: a step towards solving the equation for ‘X’

Molecular Neurodegeneration
Background While the temporal profile of amyloid (Aβ) and tau cerebrospinal fluid (CSF) biomarkers along the Alzheimer’s disease (AD) continuum is well-studied, chronological changes of CSF proteins reflecting other disease-relevant processes, denoted ‘X’

Association of CSF proteins with tau and amyloid β levels in asymptomatic 70-year-olds

Alzheimer’s Research & Therapy, 2021
Background Increased knowledge of the evolution of molecular changes in neurodegenerative disorders such as Alzheimer’s disease (AD) is important for the understanding of disease pathophysiology and also crucial to be able to identify and validate ...

Alzheimer disease and tau protein

Rinsho Shinkeigaku, 2012
To elucidate involvement of tau protein in neurodegenerative processes in Alzheimer disease and related disorders, self-assembly process and degradative process of tau protein were examined. To understand the mechanisms of the aggregation, binding affinity of tau protein to 14-3-3 protein, which converts tau to a filamentous or aggregated form.

White Matter and Perivascular Imaging Changes in Alzheimer's Disease and Cerebral Amyloid Angiopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Peak‐width of skeletonized mean diffusivity (PSMD) and diffusion tensor imaging–analysis along the perivascular space (DTI‐ALPS), reflecting white matter integrity and glymphatic function, are altered in Alzheimer's disease (AD).

Tau Oligomers Neurotoxicity

, 2021
Although the mechanisms of toxic activity of tau are not fully recognized, it is supposed that the tau toxicity is related rather not to insoluble tau aggregates but to its intermediate forms.

Electrochemical modulation of tau protein phosphorylation levels with biomimetic polyaniline membranes

Sensing and Bio-Sensing Research
Alzheimer's disease (AD) is hallmarked by the accumulation of hyperphosphorylated tau proteins, which disrupt microtubule stability and significantly contribute to neurodegeneration and cognitive decline.

Cerebrospinal Fluid Over Plasma Links Analytes to Cognitive Decline in Older Adults at Risk for Alzheimer's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To identify inflammatory analytes in cerebrospinal fluid (CSF) and plasma associated with cognitive decline in cognitively normal (CN) older adults at risk for Alzheimer's disease (AD). Methods In a longitudinal study of 118 CN older adults (65–80 years, 54% APOE ε4, 26% preclinical AD), 1331 CSF and 1501 plasma analytes were ...

Distribution of hyperphosphorylated tau proteins in the brains of mice and humans and its effects on neuronal activity and behaviour

, 2020
Tauopathies are a heterogeneous group of neurodegenerative diseases, characterized by the deposition of pathological tau (p-tau) proteins in distinct brain regions. The hypothesised spread of tau pathology between different brain regions is

CSF protein ratios with enhanced potential to reflect Alzheimer’s disease pathology and neurodegeneration

Molecular Neurodegeneration
Background Amyloid and tau aggregates are considered to cause neurodegeneration and consequently cognitive decline in individuals with Alzheimer’s disease (AD).
