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

Dietary intervention using nondigestible oligosaccharides, short-chain galacto-oligosaccharides (scGOS)/long-chain fructo-oligosaccharides (lcFOS), in combination with Bifidobacterium breve M-16V prevents allergic disease involving galectin-9. In addition, apical TLR9 signaling contributes to intestinal homeostasis. We studied the contribution of galectin-9 secreted by intestinal epithelial cells (IEC; HT-29 and T84) in Th1 and regulatory T-cell (Treg) polarization in vitro. IEC were grown in transwell filters, cocultured with CD3/CD28-activated human peripheral blood mononuclear cells (PBMC) and apically exposed to genomic DNA derived from B. breve M-16V or synthetic TLR9 ligand in the absence or presence of scGOS/lcFOS. Cytokine production and T-cell phenotype were determined and galectin expression by IEC was assessed. Galectin-9 was neutralized using lactose or a TIM-3-Fc fusion protein. IEC exposed to DNA from B. breve M-16V or TLR9 ligand in the presence of scGOS/lcFOS enhanced IFN-γ secretion by PBMC and increased the percentage of Th1 and Treg cells. Expression and secretion of galectin-9 by IEC was increased and neutralization of galectin-9 prevented the induction of IFN-γ secretion and also suppressed the production of IL-10 by PBMC. Furthermore, we show that galectin-9 induces Treg and Th1 polarization through interaction with antigen-presenting cells. Our findings show that galectin-9 secreted by IEC apically exposed to TLR9 ligand in the presence of scGOS/lcFOS is involved in Th1 and Treg polarization and may be a promising target to prevent or treat allergic disease.
