In humans, misfolding of the protein tau leads to its toxic accumulation insidebrain cells, the formation of these tau aggregates into hallmark neurofibrillary tangles, neuron death, and eventually symptoms of cognitive decline such asmemory lossand diminished thinking skills. In this study the USF ...
We have shown that PHFs and SFs of truncated tau are tethered within EVs enriched in endo-lysosomal proteins in the brains of individuals with AD. This work paves the way for further in situ cryo-ET studies of neurodegenerative disease-associated protein assemblies in human brain environments. ...

Our work has demonstrated that ageand disease‐related changes to the cellular chaperone repertoire likely contribute to the abnormal buildup of tau. Recently, we have found that two Hsp90 coヽhaperones, the 52kDa FK506‐binding protein (FKBP52) and the activator of 90 kDa heat shock ...
Alzheimer’s disease (AD), the most prevalent and progressive form of senile dementia, affects an estimated 6.9 million Americans aged 65 and older [1]. It is characterized by the accumulation of amyloid beta-protein (Aβ) deposits and abnormal tau protein aggregates in the brain [18,51]....
Tau-tubulin kinase phosphorylates tau at Ser-208 and Ser-210, sites found in paired helical filament-tau Hyperphosphorylated tau protein is known to be a major component of the paired helical filaments (PHFs) that accumulate in the brain of Alzheimer's patient... K Tomizawa,A Omori,A Ohtake...
[70], tau accumulation rates were found to be rather uniform across brain regions, arguing against the notion that the build-up of tau pathology progresses in a stepwise manner, as suggested by histopathological studies. However, the discrepancy between histopathological and in vivo PET findings ...

Further characterisation of these antibodies was performed by immunohistochemical staining of brain sections and immuno-gold electronmicroscopy of isolated PHFs. Results Our work resulted in a set of high-affinity antibodies reacting with multiple epitopes spanning the entire tau protein molecule. The tau...
