Characterization of Trypanosoma cruzi infectivity, proliferation, and cytokine patterns in gut and pancreatic epithelial cells maintained in vitro.
Article in Parasitology research, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Trypanosoma cruzi infects all nucleated cells in both humans and experimental animals. As a prelude to our studies of T. cruzi pathogenesis in the gastrointestinal system, we have initiated in vitro cultures of gut (Caco-2 and HT-29) and pancreatic (Panc-1) epithelial cells. We show that along with primary human fibroblasts, all three cell lines are susceptible to infection and support proliferation of T. cruzi. Infection with T. cruzi modified dramatically the cytokines elaborated by these cells. Substantially greater quantities of IL-5 and TGF-β1 were produced by fibroblasts and Caco-2 and Panc-1 cells, whereas secretion of IFN-γ and TNF-α was greatly reduced in all three cell types. Since these cells are not known to be the primary sources of IFN-γ, we examined IFN-γ mRNA expression in these cells. Both Caco-2 and Panc-1 cells were found to express IFN-γ mRNA, validating its secretion. These findings may provide insight into signaling pathways that mediate innate immunity to T. cruzi and pathogenesis of gastrointestinal and pancreatic alterations in Chagas disease.
