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

In recent years the role of extracellular vesicles (EVs) of Gram-positive bacteria in host-microbe cross-talk has become increasingly appreciated, although the knowledge of their biogenesis, release and host-uptake is still limited. The aim of this study was to characterize the EVs released by the dairy isolate Lactiplantibacillus plantarum BGAN8 and to gain an insight into the putative mechanism of EVs uptake by intestinal epithelial cells. The cryo-TEM observation undoubtedly demonstrated the release of EVs (20 to 140 nm) from the surface of BGAN8, with exopolysaccharides seems to be part of EVs surface. The proteomic analysis revealed that the EVs are enriched in enzymes involved in central metabolic pathways, such as glycolysis, and in membrane components with the most abundant proteins belonging to amino acid/peptide ABC transporters. Putative internalization pathways were evaluated in time-course internalization experiments with non-polarized HT29 cells in the presence of inhibitors of endocytic pathways: chlorpromazine and dynasore (inhibitors of clathrin-mediated endocytosis-CME) and filipin III and nystatin (disrupting lipid rafts). For the first time, our results revealed that the internalization was specifically inhibited by dynasore and chlorpromazine but not by filipin III and nystatin implying that one of the entries of L. plantarum vesicles was through CME pathway.
