Prisijungti Registracija

Comparative proteomic analysis of cerebrospinal fluid (CSF) proteins was employed for studies of the pathophysiological mechanisms in frontotemporal dementia (FTD). Two-dimensional gel electrophoresis and mass spectrometry were used for clinical screening of disease-influenced CSF proteins in 15 FTD

Previous studies have shown an association between disruption of the blood-brain-barrier (BBB) and dementias of different etiologies. The protein concentration of cerebrospinal fluid (CSF) can be used as an indirect measurement for the permeability of the BBB using the CSF/plasma

BACKGROUND: The aim of this study was firstly, to improve and validate a cerebrospinal fluid (CSF) prefractionation method followed by two-dimensional electrophoresis (2-DE) and secondly, using this strategy to investigate differences between the CSF proteome of frontotemporal dementia (FTD)

Increased intrathecal inflammatory activity in frontotemporal dementia: pathophysiological implications.

OBJECTIVE Immunological mechanisms may be part of the pathophysiological mechanisms in frontotemporal dementia (FTD), but hitherto only vague evidence of such mechanisms has been presented. The aim of this study was to compare the cerebrospinal fluid (CSF) levels of the pro-inflammatory cytokines

CSF/serum albumin ratio in dementias: a cross-sectional study on 1861 patients.

Prisijungti Registracija

A connection between dementias and blood-brain barrier (BBB) dysfunction has been suggested, but previous studies have yielded conflicting results. We examined cerebrospinal fluid (CSF)/serum albumin ratio in a large cohort of patients diagnosed with Alzheimer's disease (AD, early onset [EAD, n =

Cerebrospinal fluid analysis for diagnosis of noninflammatory, dementive and psychiatric diseases.

CSF analysis contributes to differential diagnosis of noninflammatory diseases by: 1) exclusion of a chronic or acute inflammation. 2) detection of particular brain-derived proteins, surrogate markers, corresponding to the suggested diagnosis (tumor, dementia, brain hypoxia, hemorrhage, autoimmune

Progranulin Deficient Mice Develop Nephrogenic Diabetes Insipidus.

Prisijungti Registracija

Loss-of-function mutations of progranulin are associated with frontotemporal dementia in humans, and its deficiency in mice is a model for this disease but with normal life expectancy and mild cognitive decline on aging. The present study shows that aging progranulin deficient mice develop

CSF levels of PSA and PSA-ACT complexes in Alzheimer's disease.

BACKGROUND Prostate-specific antigen (PSA) is a serine protease that in serum, is predominantly found complexed to the serine protease inhibitor alpha1-antichymotrypsin (ACT). ACT co-localizes with amyloid plaques in Alzheimer's disease (AD) brain and both PSA and ACT are detectable in cerebrospinal

Objectives: There are a few studies showing how nutritional parameters are affected according to dementia subtypes. The aim of this study was to compare the parameters characterizing nutritional status and micronutrient levels according

Self-assembly hollow manganese Prussian white nanocapsules attenuate Tau-related neuropathology and cognitive decline.

Prisijungti Registracija

Alzheimer's disease (AD) is a prevalent chronic neurodegenerative disease. However, to date, none of the developed drug candidates targeting at a single therapeutic target of AD have achieved success in clinical trials. Herein, we proposed a hypothesis of hollow manganese Prussian white nanocapsules

Progranulin as a candidate biomarker for therapeutic trial in patients with ALS and FTLD.

The loss-of-function mechanism in progranulin (PGRN) mutation carriers makes PGRN an interesting target for upregulation as a therapeutic approach in neurodegenerative diseases like frontotemporal lobar degeneration. This gives rise to several questions: (1) how stable are PGRN levels in blood and

Dysfunction of the blood-cerebrospinal fluid-barrier and N-methyl-D-aspartate glutamate receptor antibodies in dementias.

Prisijungti Registracija

N-Methyl-D-aspartate glutamate receptor (NMDA-R) antibodies (Abs) could play a role in neurodegenerative disorders. Since, in these diseases, NMDA-R Abs were detected in serum, but only sporadic in cerebrospinal fluid (CSF), the origin and impact of the Abs are still unresolved. We examined the

Increased blood-brain barrier permeability is associated with dementia and diabetes but not amyloid pathology or APOE genotype.

Blood-brain barrier (BBB) dysfunction might be an important component of many neurodegenerative disorders. In this study, we investigated its role in dementia using large clinical cohorts. The cerebrospinal fluid (CSF)/plasma albumin ratio (Qalb), an indicator of BBB (and blood-CSF barrier)

Alterations in the Peripheral Immune System in Dementia.

Alterations in the immune response that result in inflammation might play a role in the pathology of dementias. In order to analyze changes of the peripheral immune system associated with different types of dementias, we determined several innate and adaptive cell populations in whole blood using

Alzheimer's disease is characterized by two main neuropathological hallmarks: extracellular plaques of amyloid-β (Aβ) protein and intracellular aggregates of tau protein. Although tau is normally a soluble monomer that bind microtubules, in disease it forms insoluble,
