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

IL-10 plays a critical role in controlling inflammation and the anti-inflammatory functions of IL-10 are regulated based on its coordinated expression from various cellular sources, most notably T cells. Although nearly all CD4+ subpopulations can express IL-10, surprisingly little is known about the molecular mechanisms which control IL-10 induction, particularly in humans. To examine the regulation of human IL-10 expression, we created the hIL10BAC transgenic mouse. As previously reported, we observed conservation of myeloid-derived IL-10 expression but found that human IL-10 was only weakly expressed in splenic CD4+ T cells from hIL10BAC mice. Since DNA methylation is an important determinant of gene expression profiles, we assessed the patterns of DNA methylation in the human and mouse IL10 genes in naïve and activated CD4+ T cells. Across mouse and human IL10 there were no obvious patterns of CpG methylation in naïve CD4+ T cells following polyclonal activation. Overall however, the human IL10 gene had significantly higher levels of DNA methylation. Interestingly, coculture with the IL-10-inducing cytokine IL-27 lead to a site-specific reduction in methylation of the mouse but not human IL10 gene. Demethylation was specifically localized to an intronic site adjacent to a known regulatory region. Our findings indicate that while the mouse and human IL10 genes undergo variable changes in DNA methylation during CD4+ T cell activation, IL-27 appears to influence DNA methylation in a particular intronic region thus associating with IL-10 expression.
