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

Lymphoid chemokines are crucial for the development and maintenance of lymphoid organs, but their ectopic expression in non-lymphoid tissues is implicated in both local response to infection and chronic organ-specific autoimmunity. Production of one such chemokine, C-X-C motif ligand 13 (CXCL13), within the central nervous system (CNS) has been linked to the pathogenesis of multiple sclerosis (MS), although little is known about factors controlling its expression in different neural cell types and across a range of disease states. We provoked acute neuroinflammation in experimental animals without causing any associated demyelination using neuroadapted Sindbis virus (NSV) to better understand the sources and regulators of this chemokine in the CNS. We found that mice genetically deficient in the transcription factor, interferon (IFN) regulatory factor-7 (IRF7), made significantly higher CXCL13 protein levels in the CNS compared with wild-type (WT) controls. Microglia proved to be the main producer of CXCL13 in the brain during infection of both WT and IRF7(-/-) mice, and primary microglia cultured in vitro generated CXCL13 following stimulation with either virus particles or synthetic Toll-like receptor (TLR) ligands. Microglia cultured from IRF7(-/-) mice selectively overproduced CXCL13, and manipulation of extracellular type-I IFN levels demonstrated the existence of a negative feedback loop whereby type-I IFN receptor signaling specifically suppressed microglial CXCL13 release. Since IFN-β is used to treat patients with relapsing-remitting MS and yet acts through unknown mechanisms, we speculate that suppressed lymphoid chemokine production by microglia could contribute to its therapeutic effects.
