IL-1ra and CCL5, but not IL-10, are promising targets for treating SMA astrocyte-driven pathology.

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
Spinal muscular atrophy (SMA) is a pediatric genetic disorder characterized by the loss of spinal cord motor neurons (MNs). Although the mechanisms underlying MN loss are not clear, current data suggest that glial cells contribute to disease pathology. We have previously found that SMA astrocytes drive microglial activation and MN loss potentially through the upregulation of NF-κB-mediated pro-inflammatory cytokines. In this study, we tested the ability of neutralizing C-C motif chemokine ligand 5 (CCL5) while increasing either interleukin-10 (IL-10) or IL-1 receptor antagonist (IL-1ra) to reduce the pro-inflammatory phenotype of SMA astrocytes. While IL-10 was ineffective, IL-1ra ameliorated SMA astrocyte-driven glial activation and MN loss in induced pluripotent stem cell-derived cultures in vitro. In vivo AAV5 delivered IL-1ra overexpression, and miR-30 small hairpin RNA knockdown of CCL5 made modest but significant improvements in lifespan, weight gain, MN number, and motor function of SMNΔ7 mice. These data identify IL-1ra and CCL5 as possible therapeutic targets for SMA and highlight the importance of glial-targeted therapeutics for neurodegenerative disease.
