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

Although transforming growth factor-β (TGF-β) has been shown to positively regulate the development of murine T helper type 17 (Th17) cells, which of the intracellular signaling pathways are involved is controversial. We examined Smad-dependent and -independent signaling molecules downstream of the TGF-β receptor (TGFβR) involved in Th17 differentiation of naive murine CD4(+)CD62L(+) T cells. During Th17 differentiation of wild-type T cells, Smad2/3 was phosphorylated, indicating activation of the canonical Smad pathway. T cells lacking TGFβRII did not differentiate into Th17, whereas T cells treated with a TGFβRI kinase inhibitor (SB-431542) or overexpression of inhibitory Smad7 retained a low amount of Th17 polarization despite absent Smad2/3 phosphorylation. Using protein antibody arrays we found an increase of expression and phosphorylation of the following Smad-independent signaling molecules in Th17-polarized wild-type T cells: AKT1(Tyr474), AKT2 (Ser474), ERK1-p44/42 MAPK(Tyr204), mTOR(Thr2446), p38 MAPK(Thr180), Rac1/cdc42(Ser71), SAPK/JNK(Tyr185) and SP1(Thr739). Pharmacological inhibition of AKT/mammalian target of rapamycin (mTOR) signaling with rapamycin or LY294002 decreased Th17 differentiation of wild-type T cells, and completely abolished interleukin-17 production in T cells with overexpression of Smad7. Rapamycin and LY294002 also decreased induced regulatory T cell differentiation, but only had minor additive effects to Smad7 overexpression. Finally, inhibitors of mitogen-activated protein kinase (MAPK) blocked in vitro polarization of Th17 cells. Our data show that Smad-dependent and -independent intracellular pathways contribute to murine Th17 differentiation.
