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 (IL) 36 is a member of the IL-1-like proinflammatory cytokine family that has a protective role in mucosal immunity. We hypothesized that mucosal delivery of IL-36γ to the intestine would be a very effective way to prevent intestinal diseases. Here, we genetically engineered a lactic acid bacterium, Lactococcus lactis, to produce recombinant mouse IL-36γ (rmIL-36γ). Western blotting and enzyme-linked immunosorbent assay results showed that the engineered strain (NZ-IL36γ) produced and hypersecreted the designed rmIL-36γ in the presence of nisin, which induces the expression of the recombinant gene. We administered NZ-IL36γ to mice via oral gavage, and collected the ruminal contents and rectal tissues. Colony PCR using primers specific for NZ-IL36γ, and enzyme-linked immunosorbent assay to measure the rmIL-36γ concentrations of the ruminal contents showed that NZ-IL36γ colonized the mouse intestines and secreted rmIL-36γ. A microbiota analysis revealed increased abundances of bacteria of the genera Acetatifactor, Eubacterium, Monoglobus, and Roseburia in the mouse intestines. Real-time quantitative PCR of the whole colon showed increased Muc2 expression. An in vitro assay using murine colorectal epithelial cells and human colonic cells showed that purified rmIL-36γ promoted Muc2 gene expression. Taken together, these data suggest that NZ-IL36γ may be an effective and attractive tool for delivering rmIL-36γ to improve the intestinal environment.
