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

Langerhans cells (LCs) are skin-resident dendritic cells (DC) located in the epidermis that migrate to skin-draining lymph nodes during the steady state and in response to inflammatory stimuli. TGF-β1 is a critical immune regulator that is highly expressed by LCs. The ability to test the functional importance of LC-derived TGF-β1 is complicated by the requirement of TGF-β1 for LC development and by the absence of LCs in mice with an LC-specific ablation of TGF-β1 or its receptor. To overcome these problems, we have engineered transgenic huLangerin-CreER(T2) mice that allow for inducible LC-specific excision. Highly efficient and LC-specific expression was confirmed in mice bred onto a YFP Cre reporter strain. We next generated huLangerin-CreER(T2) × TGF-βRII(fl) and huLangerin-CreER(T2) × TGF-β1(fl) mice. Excision of the TGFβRII or TGFβ1 genes induced mass migration of LCs to the regional lymph node. Expression of costimulatory markers and inflammatory cytokines was unaffected, consistent with homeostatic migration. In addition, levels of p-SMAD2/3 were decreased in LCs from wild-type mice before inflammation-induced migration. We conclude that TGF-β1 acts directly on LCs in an autocrine/paracrine manner to inhibit steady-state and inflammation-induced migration. This is a readily targetable pathway with potential therapeutic implications for skin disease.
