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

Lymphocytes residing in the intestinal epithelium are exclusively T cells and account for one of the largest collection of T cells in the organism. However, their function remains obscure. We and others have shown that the development of intestinal intraepithelial T cells is compromised in mutant mice prone to chronic intestinal inflammation. These results led us to directly assess their role in regulating the development of colitis secondary to transfer of primary splenic TCRalphabeta(+)CD4(+)CD45RB(hi) T cells into severe combined immunodeficiency (SCID) mice. Here we demonstrate that prior reconstitution of SCID recipients with intraintestinal TCRalphabeta(+)CD4(-)CD8alpha(+)beta(-) T cells prevents disease, and does so in an interleukin (IL)-10-dependent fashion. In contrast, reconstitution with either TCRgammadelta(+) or TCRalphabeta(+)CD4(-) CD8alpha(+)beta(+) intestinal T cells did not prevent colitis. TCRalphabeta(+)CD4(-)8alpha(+)beta(-) T cells are unique to the intestinal epithelium of both rodents and humans. Previous repertoire analyses of TCRalphabeta(+)CD4(-)CD8alpha(+)beta(-) T cells revealed a high proportion of cells expressing high affinity, self-specific TCR within this subset. We demonstrate that monoclonal, self specific TCRalphabeta(+)CD4(-)CD8alpha(+)beta(-) cells derived from TCR transgenic mice also prevent the onset of colitis. Thus, intestinal TCRalphabeta(+)CD4(-)CD8alpha(+)beta(-) T cells, selected based on their self-reactivity, maintain gut integrity in a IL-10-dependent fashion.
