Splenic Dendritic Cells from Antigen-Fed Mice Induced Antigen-Specific T Cell Unresponsiveness in vivo.
Article in Cytotechnology, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
While it is well-known that orally fed antigens induce systemic T cell tolerance (oral tolerance), the mechanism by which this occurs, however, remains unclear. In the present study, we examined the role of splenic dendritic cells (DCs) in the process of oral tolerance induction and/or maintenance, by using an adoptive transfer system of antigen (Ag)-specific CD4(+) T cells from ovalbumin (OVA)-specific T cell receptor transgenic mice and DCs from OVA-fed BALB/c mice. Transfer of splenic DCs from OVA-fed mice reduced IL-2 productivity and the proliferative activity of pre-transferred Ag-specific CD4(+) T cells to ex vivo Ag stimulation. There were no changes in expression levels of costimulatory molecules on DCs from OVA-fed mice. Our results show that orally administered Ags induce systemic T cell unresponsiveness through splenic DCs without inducing cell division of T cells, thus providing evidence that splenic DCs are involved in oral tolerance induction.
