Serial amplification of tau filaments using Alzheimer's brain homogenates and C322A or C322S recombinant tau.
Article in FEBS letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The assembly of tau into amyloid filaments is a hallmark of Alzheimer's disease (AD) and other tauopathies. Cryo-EM revealed the existence of disease-specific tau folds, which are challenging to replicate in vitro. We studied three full-length recombinant 0N3R tau forms (the wild-type and the C322A and C322S variants) using an RT-QuIC assay with brain homogenate seeding. C322A tau formed filaments resembling AD paired helical filaments (PHFs) but with a more open C-shaped core. C322S tau yielded structurally distinct filaments with an ordered C-terminal region. Both mutants seeded further aggregation, whereas the wild-type showed poor reproducibility and mainly unfolded aggregates. These results highlight the importance of optimised conditions to produce disease-relevant tau filaments and aid the development of targeted therapies. Impact statement We investigated the seeded assembly of 0N3R tau and its two mutational variants C322A and C322S, using Alzheimer's disease brain homogenates in a real-time quaking-induced conversion (RT-QuIC) assay. The C322A variant formed filaments partially resembling the AD PHF structure, showing the importance of optimised conditions to produce disease-relevant tau filaments.
