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 innate immunity system and extracellular microvesicles (ExMVs) both emerged early in the evolution of life, which is why its innate immunity cellular arm and its soluble-component arm learned, understood, and adapted to the "language" of ExMVs. This was most likely the first language of cell-cell communication during evolution, which existed before more specific intercellular crosstalk involving specific ligands and receptors emerged. ExMVs are involved in several processes in the body, including immune and coagulation responses, which are part of inflammation. In this review we will briefly highlight what is known about how ExMVs regulate the function of the cellular arm of innate immunity, including macrophages, monocytes, granulocytes, natural killer cells, and dendritic cells, and affect the soluble components of this system, which consists of the complement cascade (ComC) and soluble, circulating, pattern-recognition receptors (collectins, ficolins, and pentaxrins). These effects are direct, due to the fact that ExMVs affect the biological functions of innate immunity cells and may directly interact with soluble components of this system. Moreover, by activating coagulation proteases, ExMVs may also indirectly activate the ComC. In this review, we will use the term "extracellular microvesicles" (ExMVs) to refer to these small, spheroidal blebs of different sizes, which are surrounded by a membrane lipid layer. We will focus on the role of both ExMVs released during cell-surface membrane budding and smaller ExMVs, known as exosomes, which are derived from the budding of the endosomal membrane compartment. Finally, we will provide a brief update on the potential therapeutic applications of ExMVs, with a special emphasis on innate immunity.
