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)-10 and transforming growth factor (TGF)-beta1 are suppressor cytokines that frequently occur together during a regulatory T cell response. Here we used a one gene doxycycline (Dox)-inducible plasmid encoding TGF-beta1 to analyze this association and test its utility. In initial studies, we showed that intranasal administration of this plasmid (along with Dox) led to the appearance of TGF-beta1-producing cells (in spleen and lamina propria) and the almost concomitant appearance of IL-10-producing cells. Moreover, we showed that these cells exert Dox-regulated suppression of the T helper cell (Th)1-mediated inflammation in trinitrobenzene sulfonic acid colitis. In subsequent in vitro studies using retroviral TGF-beta1 expression, we established that IL-10 production by Th1 cells occurs after exposure to TGF-beta1 from either an endogenous or exogenous source. In addition, using a self-inactivating retrovirus luciferase reporter construct we showed that TGF-beta1 induces Smad4, which then binds to and activates the IL-10 promoter. Furthermore, intranasal TGF-beta1 plasmid administration ameliorates bleomycin-induced fibrosis in wild-type but not IL-10-deficient mice, strongly suggesting that the amelioration is IL-10 dependent and that IL-10 protects mice from TGF-beta1-mediated fibrosis. Taken together, these findings suggest that the induction of IL-10 by TGF-beta1 is not fortuitous, but instead fulfills important requirements of TGF-beta1 function after its secretion by regulatory T cells.
