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

Interleukin-10 (IL-10) is the most potent anti-inflammatory cytokine in the body and plays an essential role in determining outcomes of many inflammatory diseases. Cellular metabolism is a critical determinant of immune cell function; however, it is currently unclear whether metabolic processes are specifically involved in IL-10 production. In this study, we aimed to find the central metabolic molecule regulating IL-10 production of macrophages, which are the main producers of IL-10. Transcriptomic analysis identified that metabolic changes were predominantly enriched in Kupffer cells at the early inflammatory phase of a mouse endotoxemia model. Among them, pyruvate dehydrogenase kinase (PDK)-dependent acute glycolysis was negatively involved in IL-10 production. Inhibition or knockdown of PDK selectively increased macrophage IL-10 expression. Mechanistically, PDK inhibition increased IL-10 production via profound phosphorylation of adenosine monophosphate (AMP)-activated protein kinase alpha 1 (AMPKα1) by restricting glucose uptake in lipopolysaccharide-stimulated macrophages. AMPKα1 consequently activated p38 mitogen-activated protein kinase, c-Jun N-terminal kinase, and cyclic AMP-responsive element-binding protein to regulate IL-10 production. Our study uncovers a previously unknown regulatory mechanism of IL-10 in activated macrophages involving an immunometabolic function of PDK.
