2025年2月18日 · We found that p-tau had the same characteristics in plasma as in the brain from AD patients and thus can serve as a useful screening test for AD. The VeraBIND Tau test, a novel plasma assay for active tau pathology, identifies individuals with positive F18MK6240 tau-PET signal regardless of amyloid status ( Feb 2025 conference news ).

2025年3月28日 · Tau inclusions can also feature in both diseases, and in 2021, scientists led by Bernardino Ghetti of Indiana University School of Medicine in Indianapolis reported that tau filaments in both conditions assumed the AD-tau fold (Hallinan et al., 2021). The AD-tau branch wasn’t the only one to sprout new offshoots. The related CTE-fold, which ...

The revelation that tau aggregates can pass between cells, corrupting their intracellular counterparts, changed how the Alzheimer’s field studies tau pathology. At this year’s AD/PD meeting, held in March 5-9 in Lisbon, Portugal, researchers focused less on how the microtubule-binding protein travels from place to place, and more on what ...

2014年8月14日 · That is, tau aggregates present in brain homogenate can elicit further tau aggregation, presumably via a prion-like mechanism. Seeding activity was first detected at 1.5 months of age in these mice, indicating that proteopathic tau seeding is an early phenotype in this model (Holmes et al., 2014).

2023年8月10日 · The Cryo-electron tomography of tau fibril structures is very interesting, since they comprise not only AD-type tau misfolding but also CTE-like tau misfolding, suggesting a heterogenous origin of tau fibrils in AD brain. Since CTE tau pathology is frequently found in glial tangles as well as in neurofibrillary tangles, I was curious if there ...

2024年3月1日 · AD pathology is defined by fluid or imaging markers under the amyloid-tau-neurodegeneration (ATN) framework, whereby cerebrospinal fluid phosphotau-181 or tau PET reflect tau proteinopathy. PET scans are more onerous and expensive than plasma analysis, while p-tau181 tracks amyloid pathology as well, if not better, than tangles ( Apr 2020 ...

2022年12月29日 · In one of the small Swedish cohorts, plasma BD-tau distinguished 24 biomarker-diagnosed AD cases from 36 controls with an area under the curve of 1.0, indicating perfect sensitivity and specificity. BD-tau identified clinically diagnosed AD from other neurodegenerative diseases with AUCs of 0.78 to 0.99.

2020年7月29日 · The paper by Palmqvist et al. on blood plasma phospho-tau 217 is a remarkable clinical study clearly demonstrating the value of phospho-tau 217 for identifying AD pathology. These findings advance our understanding of how p-tau217 is related to amyloid and tau PET and the stages of AD, and how it can be utilized as a blood biomarker.

2024年5月10日 · TRx0237 (LMTX™) is a second-generation tau protein aggregation inhibitor for the treatment of Alzheimer's disease (AD) and frontotemporal dementia. It is a replacement formulation for Rember ® , the first company's first proprietary formulation of …
