Hyperphosphorylation and dysregulation of exon 10 splicing of Tau are pivotally involved in pathogenesis of Alzheimer disease (AD) and/or other tauopathies. Alternative splicing of Tau exon 10, which encodes the second microtubule-binding repeat, generates Tau isoforms containing three and four microtubule-binding repeats, termed 3R-Taus and 4R-Taus, respectively. Dual specificity tyrosine-phos...

The spread of tau pathology correlates with cognitive decline in Alzheimer's disease. In vitro, tau antibodies can block cell-to-cell tau spreading. Although mechanisms of anti-tau function in vivo are unknown, effector function might promote microglia-mediated clearance. In this study, we investigated whether antibody effector function is required for targeting tau. We compared efficacy in viv...

Filamentous tau inclusions in neurons and glia are neuropathological hallmarks of sporadic and familial tauopathies. Because tau gene mutations are pathogenic for the autosomal dominant tauopathy "frontotemporal dementia and parkinsonism linked to chromosome 17," tau abnormalities are implicated directly in the onset and/or progression of disease. Although filamentous tau aggregates are acknowl...

We study the $d^2 \Gamma_d /(d\omega d\cos\theta_d) $, $d\Gamma_d /d\cos\theta_d$ and $ d\Gamma_d /dE_d distributions, which are defined in terms of visible energy polar angle charged particle from $\tau-$decay $b\to c \tau\, (\mu \bar \nu_\mu \nu_\tau,\pi \nu_\tau,\rho\nu_\tau) \bar\nu_\tau$ reactions. The first two contain information on transverse tau-spin, tau-angular tau-angular-spin asymm...

Background: Tau protein is believed to be stationary while bound to microtubules. Results: Tau molecules can diffuse along microtubules over distances up to several micrometers. Conclusion: Tau diffusion on microtubules is a novel mechanism for tau dispersion in cells. Significance: Modulation of tau binding and diffusion on microtubules by local modifications of microtubules can provide a tool...

nowadays, air pollution is one of the major problems in developed and developing countries. in recent years, effects of air pollution on neuroinflammatory diseases such as alzheimer disease and parkinson disease have been studied. researches on polluted cities citizens indicate increasing in central nervous system (cns) inflammatory factors in comparison with clean cities; also air pollution ex...

Neurofibrillarly tangles (NFTs) are seen most patients, who shows dementia, while β amyloid deposition observed specifically in AD patients. NFTs observe first from coeruleus and entorhinal cortex, and then spread to neocortex, which well explain clinical progression of AD, such as memory problem to dementia. Tau fibrils are the major component of NFT. Before forming tau fibrils, tau binds toge...

The neurodegenerative tauopathies are a clinically diverse group of diseases typified by the pathological self-assembly of the microtubule-associated tau protein. Although tau nitration is believed to influence the pathogenesis of these diseases, the precise residues modified, and the resulting effects on tau function, remain enigmatic. Previously, we demonstrated that nitration at residue Tyr2...

One of the main hallmarks of the fronto-temporal dementia with Parkinsonism linked to chromosome 17 (FTDP-17) is the accumulation of neurofibrillary tangles in the brain as an outcome of the aggregation of mutated tau protein. This process occurs due to a number of genetic mutations in the MAPT gene. One of these mutations is the ∆K280 mutation in the tau R2 repeat domain, which promotes the ag...

TAU is a microtubule-associated protein that under pathological conditions such as Alzheimer's disease (AD) forms insoluble, filamentous aggregates. When 20 years after TAU's discovery the first TAU transgenic mouse models were established, one declared goal that was achieved was the modeling of authentic TAU aggregate formation in the form of neurofibrillary tangles. However, as we review here...
