Interferon regulatory factor 3 inhibits astrocyte inflammatory gene expression through suppression of the proinflammatory miR-155 and miR-155*.
Article in Glia, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 78 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
Astrocytes, together with microglia and macrophages, participate in innate inflammatory responses in the CNS. Although inflammatory mediators such as interferons generated by astrocytes may be critical in the defense of the CNS, sustained unopposed cytokine signaling could result in harmful consequences. Interferon regulatory factor 3 (IRF3) is a transcription factor required for IFNβ production and antiviral immunity. Most cells express low levels of IRF3 protein, and the transcriptional mechanism that upregulates IRF3 expression is not known. In this study, we explored the consequence of adenovirus-mediated IRF3 gene transfer (Ad-IRF3) in primary human astrocytes. We show that IRF3 transgene expression suppresses proinflammatory cytokine gene expression upon challenge with IL-1/IFNγ and alters astrocyte activation phenotype from a proinflammatory to an anti-inflammatory one, akin to an M1-M2 switch in macrophages. This was accompanied by the rescue of neurons from cytokine-induced death in glial-neuronal co-cultures. Furthermore, Ad-IRF3 suppressed the expression of microRNA-155 and its star-form partner miR-155*, immunoregulatory miRNAs highly expressed in multiple sclerosis lesions. Astrocyte miR-155/miR155* were induced by cytokines and TLR ligands with a distinct hierarchy and involved in proinflammatory cytokine gene induction by targeting suppressor of cytokine signaling 1, a negative regulator of cytokine signaling and potentially other factors. Our results demonstrate a novel proinflammatory role for miR-155/miR-155* in human astrocytes and suggest that IRF3 can suppress neuroinflammation through regulating immunomodulatory miRNA expression. © 2011 Wiley-Liss, Inc.
