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

Human astroviruses (HAstVs) are a leading cause of viral gastroenteritis in children worldwide. Recently the neonatal Fc receptor (FcRn) was identified as a receptor for HAstV, however the molecular basis for the FcRn-HAstV interaction remained unclear. Here, we report the crystal structure of FcRn bound to the HAstV capsid spike domain at 3.4 angstroms resolution. We show that all classical HAstV spikes bind to FcRn and we identify three conserved HAstV spike residues that mediate binding to FcRn. Using competition binding assays, we show that the HAstV spike competes with IgG for binding to FcRn. Additionally, we demonstrate that the FcRn inhibitor, nipocalimab, and anti-HAstV neutralizing monoclonal antibodies block HAstV spike binding to FcRn, revealing their neutralization mechanisms and supporting their therapeutic potential. Overall, our findings illuminate a crucial interaction in the HAstV life cycle, which may help to inform the development of a HAstV vaccine and antibody therapies.
