Coding region and intronic mutations in the tau gene cause frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17). We have previously reported that ABalphaC, a major form of protein phosphatase 2A (PP2A) in brain, binds tightly to tau protein in vitro and is a major tau
Frontotemporal dementia with parkinsonism (FTDP-17) is an autosomal dominant disorder that presents clinically with dementia, extrapyramidal signs, and behavioral disturbances in mid-life and progresses to death within 5 to 10 years. Pathologically, the disorder is characterized by variable neuronal
The peptidyl-prolyl cis-trans isomerase (PPIase) Pin1 modulates the activity of a range of target proteins involved in the cell cycle, transcription, translation, endocytosis, and apoptosis by facilitating dephosphorylation of phosphorylated serine or threonine residue preceding a proline
A hexanucleotide repeat expansion in the chromosome 9 open reading frame 72 gene (C9orf72) was recently identified as the most common genetic cause of frontotemporal dementia/amyotrophic lateral sclerosis. Here we describe the clinical, pathologic, and genetic features of a Finnish C9orf72 expansion
Since valosin-containing protein mutations were reported as a cause of hereditary inclusion body myositis associated with Paget's disease of the bone and frontotemporal dementia, many new mutations have been described in the last decade. We report on a 46-year-old German male with a progressive
Background: Alterations in the methionine cycle and abnormal tau phosphorylation are implicated in many neurodegenerative diseases, including Alzheimer's disease and frontotemporal dementia. rTg4510 mice express mutant human P301L tau and
An important challenge in the field of Parkinson's disease (PD) is to develop disease modifying therapies capable of stalling or even halting disease progression. Coupled to this challenge is the need to identify disease biomarkers, in order to identify pre-symptomatic hallmarks of disease and
Detergent insoluble inclusions of TDP-43 protein are hallmarks of the neuropathology in over 90 % of amyotrophic lateral sclerosis (ALS) cases and approximately half of frontotemporal dementia (FTLD-TDP) cases. In TDP-43 proteinopathy disorders, lesions containing aggregated TDP-43 protein are
Objective
To identify novel CSF biomarkers in
GRN-associated
frontotemporal dementia (
FTD) by proteomics using mass spectrometry (MS).
Methods
Unbiased MS was applied to CSF samples from 19 presymptomatic and 9 symptomatic
GRN mutation
Alzheimer's disease (AD) is the leading cause of dementia worldwide accounting for around 70% of all cases. There is currently no treatment for AD beyond symptom management and attempts at developing disease-modifying therapies have yielded very little. These strategies have traditionally targeted
Inclusion body myopathy with Paget disease of the bone (PDB) and/or frontotemporal dementia (IBMPFD, OMIM 167320), is a progressive autosomal dominant disorder caused by mutations in the Valousin-containing protein (VCP, p97 or CDC48) gene. IBMPFD can be difficult to diagnose. We assembled data on a
Inclusion body myopathy associated with Paget's disease of bone and frontotemporal dementia (IBMPFD) is a progressive, fatal genetic disorder with variable penetrance, predominantly affecting three main tissue types: muscle (IBM), bone (PDB), and brain (FTD). IBMPFD is caused by mutations in the
Methylmercury (MeHg) is a well-known neurotoxicant inducing neuronal degeneration in the central nervous system. This in vivo study investigated the involvement of tau hyperphosphorylation in MeHg-induced neuropathological changes in the mouse brain, because abnormal tau hyperphosphorylation causes
In Alzheimer's disease and related disorders, the microtubule-associated protein Tau is abnormally hyperphosphorylated and aggregated into neurofibrillary tangles. Mutations in the tau gene cause familial frontotemporal dementia. To investigate the molecular mechanisms responsible for Tau-induced
Neurofibrillary degeneration (ND) is both a pivotal and a primary lesion of Alzheimer disease (AD) and related tauopathies. To date in all known tauopathics including AD, the neurofibrillary changes, whether of paired helical filaments (PHF), twisted ribbons or straight filaments (SF) are made up of
