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

Dendritic cells (DCs) play an instrumental role in regulating tolerance to self-antigens and preventing autoimmunity. One mechanism by which "tolerogenic" DCs are established is through the inhibitory effects of apoptotic cells (ACs). Immature DCs encountering ACs are resistant to stimuli that activate and mature DCs. We have shown that the Mer receptor tyrosine kinase (MerTK) plays a key role in transducing inhibitory signals upon binding of ACs, which in turn involve the phosphatidylinositol 3-kinase (PI3K) pathway. Nevertheless, the molecular basis for AC-induced inhibition of DCs is ill defined. In the current study, the proximal signaling events induced by MerTK after AC binding were studied. AC treatment of bone marrow-derived or splenic DCs established a complex consisting of MerTK, the nonreceptor tyrosine kinase c-Src, the transcription factor STAT3, and PI3K. In contrast, AC treatment of DCs lacking MerTK expression failed to increase c-Src and STAT3 activation. In addition, the inhibitory effects of ACs were blocked by treating DCs with pharmacologic inhibitors or siRNA specific for c-Src and STAT3. These findings demonstrate that AC-induced inhibition of DCs requires MerTK-dependent activation of c-Src and STAT3, and provide evidence for novel roles for c-Src and STAT3 in the immunoregulation of DCs.
