Comprehensive mapping of the signaling events evoked by SARS-CoV-2 variants delta and omicron in human astrocytes.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
COVID-19 causes a wide range of complications in the central nervous system, including encephalitis and other neurological symptoms such as memory problems, psychological disorders, depression, and anxiety. We present comprehensive data on the changes in gene expression levels in astrocytes infected with the Delta or Omicron variants of SARS-CoV-2. In RNA-seq data, we found 346 genes that were significantly evoked (197 up- and 149 down-regulated) in astrocytes challenged with the Omicron variant, compared to 341 evoked genes (215 up- and 126 down-regulated) in the Delta variant. A surprisingly large number of genes were exclusively evoked by Delta (82 up- and 48 downregulated) and Omicron variants (65 up and 60 downregulated). Numerous pathways, including those pertaining to the neuronal system, metabolism, response to viral infection, signal transduction, cytokine signaling, and homeostasis, were dysregulated in infected astrocytes. In this report we have dissected major pathways that are related to pathogen recognition, integrity of the BBB and glia limitans, and neurological disorders that could lead to neurological symptoms listed above. Our findings also reveal dysregulation of a large number of non-coding RNAs. The data presented here may help us better understand the role of astrocytes in the neurological disorders seen in COVID-19 patients.
