ERMAP attenuates DSS-induced colitis in mice by regulating macrophage and T cell functions.

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.
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
BACKGROUND &
aimsBoth macrophages and T cells play a critical role in inflammatory bowel disease (IBD) development. Since our previous studies have shown that a novel immune checkpoint molecule erythrocyte membrane-associated protein (ERMAP) affects macrophage polarization and negatively regulates T cell responses, we investigated the effects of ERMAP on DSS-induced colitis progression in mice.
methodsC57BL/6 mice developed a dextran sodium sulfate (DSS) colitis model, treated with control Fc protein (Control Ig) and ERMAP-Fc fusion protein (ERMAP-Ig) for 12 days to assess colitis severity by disease activity index (DAI), weight loss, colon length, histology, flow cytometry, Q-PCR, WB, ELISA, and the effect of adoptive transfer of ERMAP knockout mice (ERMAP
resultsWe show here that administration of ERMAP protein significantly increases the proportion of anti-inflammatory M2-type macrophages and inhibits T cell activation and proliferation in DSS-induced colitis mice. Knockdown of ERMAP in RAW264.7 macrophages reduces M2-type macrophage polarization and increases T cell responses. Adoptive transfer of macrophages from ERMAP
conclusionsIn summary, our results suggest that administration of ERMAP can protect DSS-induced colitis in mice by regulating T cell and macrophage functions. This study adds to the evidence for various mechanistic pathways associated to the pathogenesis of IBD, which could subsequently be translated to novel therapeutics.
