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

backgroundIntestinal ischemia/reperfusion (I/R) disrupts intestinal mucosal integrity and immunoglobulin A (IgA) generation. It has recently been shown that the programmed cell death-1 receptor (PD-1) plays a crucial role in regulating intestinal secreted IgA (sIgA).

aimsTo evaluate changes in PD-1 and PD-ligand 1 (PD-L1) expression on Peyer's patches (PP) CD4(+) T cells and to investigate the correlation between PD-1/PD-L1 and intestinal IgA production/mucosal integrity in mice following intestinal I/R.

methodsI/R injury was induced by clamping the superior mesenteric artery for 1 h followed by 2-h reperfusion. PD-1/PD-L1 expression on PP CD4(+) T cells was measured in I/R and sham-operated mice. Additionally, transforming growth factor-β1 (TGF-β1) and interleukin-21 (IL-21) mRNA in CD4(+) T cells and IgA(+) and IgM(+) in PP B cells, as well as intestinal mucosal injury and sIgA levels, were assessed.

resultsPD-1/PD-L1, TGF-β1, and IL-21 expression was down-regulated after intestinal I/R. Furthermore, IgA(+) B cells decreased and IgM(+) B cells increased in mice with intestinal I/R. Importantly, decreased PD-1/PD-L1 expression was correlated with increased mucosal injury and decreased IgA levels, as well as with decreased TGF-β1 and IL-21 expression.

conclusionsIntestinal I/R inhibits PD-1/PD-L1 expression on PP CD4(+) T cells, which was associated with an impaired intestinal immune system and mechanical barriers. Our study indicates that PD-1/PD-L1 expression on CD4(+) T cells may be involved in the pathogenesis of intestinal I/R injury.
