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

STING is an important component in the host innate immune system where its activation by cyclic dinucleotides culminates in the production of interferons and pro-inflammatory cytokines that mediate host defence against infection. While the mechanisms that govern STING-induced interferon production have been comprehensively characterised, how pro-inflammatory cytokines are produced downstream of STING remains less understood. Here we discover that IRF3 is critical for effective STING-mediated inflammatory cytokine production from macrophages as those lacking IRF3 display significant defects. Interestingly, the loss of IRF3 does not impact the activation of the prominent pro-inflammatory transcription factor, NF-κB, but rather affects the AP-1 transcriptional complex. We further discover the role of IRF3 in STING inflammatory responses is independent of its phosphorylation and distinct from its role as a transcription factor for induction of type I interferons. This additional activity of IRF3 is dependent on its recruitment to the previously defined IRF3 binding motif within the C-terminal tail of STING. Hence, our findings reveal an unexpected noncanonical function of IRF3 that is critical for mediating STING-induced pro-inflammatory cytokines from macrophages.
