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

The human gastrointestinal tract is inhabited by trillions of symbiotic bacteria that form a complex ecological community and influence human physiology. Symbiotic nutrient sharing and nutrient competition are the most studied relationships in gut commensals, whereas the interactions underlying homeostasis and community maintenance are not fully understood. Here, we provide insights into a new symbiotic relationship wherein the sharing of secreted cytoplasmic proteins, called "moonlighting proteins," between two heterologous bacterial strains (Bifidobacterium longum and Bacteroides thetaiotaomicron) was observed to affect the adhesion of bacteria to mucins. B. longum and B. thetaiotaomicron were cocultured using a membrane-filter system, and in this system the cocultured B. thetaiotaomicron cells showed greater adhesion to mucins compared to that shown by monoculture cells. Proteomic analysis showed the presence of 13 B. longum-derived cytoplasmic proteins on the surface of B. thetaiotaomicron. Moreover, incubation of B. thetaiotaomicron with the recombinant proteins GroEL and elongation factor Tu (EF-Tu)-two well-known mucin-adhesive moonlighting proteins of B. longum-led to an increase in the adhesion of B. thetaiotaomicron to mucins, a result attributed to the localization of these proteins on the B. thetaiotaomicron cell surface. Furthermore, the recombinant EF-Tu and GroEL proteins were observed to bind to the cell surface of several other bacterial species; however, the binding was species dependent. The present findings indicate a symbiotic relationship mediated by the sharing of moonlighting proteins among specific strains of B. longum and B. thetaiotaomicron.
