  • Tau (PHF-1) | ALZFORUM
    PHF-1 reacts with tau phosphorylated at serine-396 and serine-404 Western blot of recombinant human tau phosphorylated in vitro with GSK3β, probed with PHF-1 WT, wild-type tau; S396A, S404A, tau in which serine-396 and serine-404, respectively, were mutated to non-phosphorylatable alanines
  • A Tale of Two T Cells—Slowing Tau Spread, Shredding White Matter
    With T cells sidelined in these CD8 knockouts, tau pathology went on the offensive By 30 weeks of age, phospho-tau had spread deeper into the brain than in CD8-intact controls (image below) Michal Schwartz of the Weizmann Institute of Science in Rehovot, Israel, noted that these findings run counter to conventional thinking
  • Tau (AT8); Phospho Tau (Ser 202, Thr 205) - ALZFORUM
    Hyperphosphorylated tau polymerizes into paired helical filaments, which aggregate to form neurofibrillary tangles, one of the defining lesions of Alzheimer’s disease Recognizes paired helical filament (PHF) tau Phosphorylation at serine 202 and threonine 205 is required for recognition by AT8
  • Better Diagnosis with Blood Test Detecting Only Tau Made in Brain
    In the December 27 Brain, Karikari reported that plasma concentration of these brain-derived forms of tau (BD-tau) tracked with cerebrospinal fluid markers of amyloid plaques and of neurofibrillary tangles, with postmortem plaque and tangle load, and with cognitive test scores better than plasma total tau and neurofilament light, the currently available blood markers of neurodegeneration
  • New Role for Tau: Making Lipid Droplets in Glia? | ALZFORUM
    Tau plays an essential role in the production of these droplets, according to a paper in the October Nature Neuroscience Using a combination of fly and mammalian cell models, scientists led by Hugo Bellen at Baylor College of Medicine in Houston, Texas, found that by virtue of it binding microtubules, tau coaxes newly formed lipid droplets to
  • 12 Phosphorylation-Mimicking Mutations Twist Tau into AD Filaments
    By mutating select residues of tau into aspartate to mimic phosphorylation, the scientists zeroed in on a combination of 12 residues that, when mutated, goad tau into pairing up into helical filaments in vitro At their core, these PHFs folded into the same back-to-back C-shaped structures found in the Alzheimer’s brain
  • Could Tau Explain the Link Between Pneumonia and Dementia?
    Strikingly, tau was necessary for most of these effects The authors believe that the release of cytotoxic tau species from pneumonia-ravaged lungs somehow exacerbates damaging inflammatory responses Whether this is the process that beckons cognitive impairment or dementia in some people with hospital-acquired pneumonia is unclear
  • When Loaded With Granulovacuolar Bodies, Neurons Combat Tau
    In mice, the number of GVB-positive neurons rises with tauopathy GVB+ neurons oppose tauopathy by cranking out ribosomal machinery, upping protein synthesis Casein kinase 1δ prompts GVB formation but is then silenced within the organelle
  • First Morsel of Results from DIAN Concurrent Amyloid and Tau Trial
    The Dominantly Inherited Alzheimer Network has been at the vanguard of AD immunotherapy development, launching the first secondary and primary prevention trials, as well as the first study of concurrent amyloid and tau therapy, Tau NexGen At the Alzheimer’s Association International Conference
  • Phospho-tau tau Ratios: Better Markers than Absolute p-Tau Levels?
    Tau isoforms measured included peptides phosphorylated at 10 residues: 111, 153, 175, 181, 199, 202, 205, 208, 217, and 231 Barthélemy calculated the p-tau tau ratios for each, using concentrations of non-phosphorylated fragments that spanned all 10 residues Which marker best predicted plaque load?
