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

Cellular susceptibility to viral infections is in part determined by the presence of a host cellular receptor. Here we use murine norovirus as a model to uncover an unappreciated connection between an intracellular lipid biosynthetic enzyme and a receptor conformation that is permissive for viral infection. The serine palmitoyltransferase complex is required for de novo sphingolipid biosynthesis and we find that its absence impairs the ability of murine norovirus to bind and enter cells. Although the serine palmitoyltransferase complex is dispensable for the surface expression of the norovirus receptor, CD300lf, serine palmitoyltransferase activity is required for CD300lf to adopt a conformation permissive for viral binding. Addition of extracellular ceramide to serine palmitoyltransferase-deficient cells chemically complements both the conformational changes of CD300lf and the cellular susceptibility to murine norovirus infection. Taken together, these data indicate that intracellular sphingolipid biosynthesis regulates the conformation of the murine norovirus receptor and therefore the tropism of murine norovirus. This indicates that intracellular biosynthetic pathways can regulate viral tropism even when the receptor for a virus is expressed on the target cell surface.
