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

Herpes simplex virus 1 (HSV-1) infection alters critical markers of Alzheimer's disease (AD) in neurons. One key marker of AD is the hyperphosphorylation of Tau, accompanied by altered levels of Tau isoforms. However, an imbalance in these Tau splice variants, specifically resulting from altered 3R to 4R MAPT splicing of exon 10, has yet to be directly associated with HSV-1 infection. To this end, we infected 2D and 3D human neural models with HSV-1 and monitored MAPT splicing and Tau phosphorylation. Further, we transduced SH-SY5Y neurons with HSV-1 ICP27, which alters RNA splicing, to analyze if ICP27 alone is sufficient to induce altered MAPT exon 10 splicing. We show that HSV-1 infection induces altered splicing of MAPT exon 10, increasing 4R-Tau protein levels, Tau hyperphosphorylation, and Tau oligomerization. Our experiments reveal a novel link between HSV-1 infection and the development of cytopathic phenotypes linked with AD progression.
