BACKGROUND Diagnosis of Creutzfeldt-Jakob disease (CJD) is made according to the typical clinical picture and can be supported by a positive 14-3-3 CSF immunoblot. Promising results for the diagnostic sensitivity and specificity of tau-protein measurement in CSF already have been described in a smaller group of patients. Both tests in a larger group of(More)
Among the first reported functions of 14-3-3 proteins was the regulation of tyrosine hydroxylase (TH) activity suggesting a possible involvement of 14-3-3 proteins in Parkinson's disease. Since then the relevance of 14-3-3 proteins in the pathogenesis of chronic as well as acute neurodegenerative diseases, including Alzheimer's disease, polyglutamine(More)
Measuring proteins in cerebrospinal fluid (CSF) has gained wide acceptance for the differential diagnosis of dementia. Some groups have already extended these investigations in Alzheimer's disease (AD) by asking how stable these markers are in follow-up analysis, if they depend on the stage of disease and whether they can be used to monitor the progression(More)
BACKGROUND Recently, TAR DNA-binding protein 43 (TDP-43) was identified as the major component of ubiquitin-positive tau-negative neuronal and glial inclusions in the most common form of frontotemporal lobar degeneration (FTLD) and in amyotrophic lateral sclerosis (ALS). It was demonstrated that different TDP-43 profiles correspond to clinical phenotypes of(More)
The diagnosis of neurodegenerative diseases with dementias requires several different test approaches and often remains uncertain. Using a proteomic approach it was shown in nine patients that heart fatty acid binding protein (H-FABP) might be a biomarker for Creutzfeldt-Jakob disease (CJD). The aim of our study was to evaluate whether H-FABP is a biomarker(More)
OBJECTIVES Decreased levels of Abeta1-42 are found in CSF of patients with AD. Because early stages of Creutzfeldt-Jakob disease (CJD) and AD share several clinical features, we investigated Abeta1-42 levels in CSF of these groups, inferring that this might give additional help in differentiating patients with CJD from AD patients. METHODS We investigated(More)
Abstract Amyotrophic lateral sclerosis (ALS) is a progressive motor neuron disease that mainly causes degeneration of the upper and lower motor neurons, ultimately leading to paralysis and death within three to five years after first symptoms. The pathological mechanisms leading to ALS are still not completely understood. Several biomarker candidates have(More)
BACKGROUND The advent of new therapeutic avenues for Alzheimer's disease (AD) calls for an improved early and differential diagnosis. METHODS With surface enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS), cerebrospinal fluid from patients with AD (n = 10) and nondemented control subjects (n = 9) was studied. RESULTS(More)
Two-dimensional polyacrylamide gel electrophoresis of CSF has been used in the diagnosis of Creutzfeldt-Jakob disease (CJD). One of the two diagnostic protein spots was identified as isoform(s) of the 14-3-3 family of abundant brain proteins. This has led to the development of one-dimensional 14-3-3 sodium dodecyl sulfate polyacrylamide gel electrophoresis(More)
The intra vitam diagnosis of different dementias is still based on clinical grounds. So far, no technical investigations have been available to support these diagnoses. For tau protein and beta-amyloid(1-42) in cerebrospinal fluid (CSF), promising results for the diagnosis of Alzheimer's disease (AD) have been reported; however, their differential(More)
