1 · What the graph read from it

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.

2 · The registry

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

introductionTau, a natively unfolded soluble protein, forms abnormal oligomers and insoluble filaments in several neurodegenerative diseases, including Alzheimer disease (AD). Tau-induced toxicity is mainly due to oligomers rather than monomers or fibrils.

methodsWe have developed monoclonal antibodies against purified low-n tau oligomers of the tau repeat domain as a tool to neutralize tau aggregation and toxicity. In vitro aggregation inhibition was tested by thioflavin S, dynamic light scattering (DLS), and atomic force microscopy (AFM). Using a split-luciferase complementation assay and fluorescence-activated cell sorting (FACS), the inhibition of aggregation was analyzed in an N2a cell model of tauopathy.

resultsAntibodies inhibited tau aggregation in vitro up to ~90% by blocking tau at an oligomeric state. Some antibodies were able to block tau dimerization/oligomerization in cells, as measured by a split-luciferase complementation assay. Antibodies applied extracellularly were internalized and led to sequestration of tau into lysosomes for degradation. DISCUSSION: Novel low-n tau oligomer specific monoclonal antibody inhibits Tau oligomerization in cells and promotes toxic tau clearance.
