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

problemFetal inflammatory signals can be propagated to maternal tissues to initiate labor via exosomes (extracellular vesicles; 30-150 nm). We tested the hypothesis that fetal membrane cells exposed to infectious and inflammatory mediators associated with preterm birth (PTB) produce exosomes with distinct protein cargo contents indicative of underlying pathobiology. METHODS OF STUDY: Fetal membrane explants (FM) as well as primary amnion epithelial (AEC) and mesenchymal cells (AMC), and chorion cells (CC) from term deliveries were maintained in normal conditions (control) or exposed to LPS 100 ng/mL or TNF-α 50 ng/mL for 48 hours. Exosomes were isolated from media by differential centrifugation and size exclusion chromatography and characterized using cryo-electron microscopy (morphology), nanoparticle tracking analysis (size and quantity), Western blot (markers), and mass spectroscopy (cargo proteins). Ingenuity pathway analysis (IPA) determined pathways indicated by differentially expressed proteins.

resultsIrrespective of source or treatment, exosomes were spherical, had similar size, quantities, and markers (ALIX, CD63, and CD81). However, exosome cargo proteins were different between FM and individual fetal membrane cell-derived exosomes in response to treatments. Several common proteins were seen; however, there are several unique proteins expressed by exosomes from different cell types in response to distinct stimuli indicative of unique pathways and physiological functions in cells.

conclusionsWe demonstrate collective tissue and independent cell response reflected in exosomes in response to infectious and inflammatory stimuli. These cargoes determined underlying physiology and their potential in enhancing inflammation in a paracrine fashion.
