TRIF-TAK1 signaling suppresses caspase-8/3-mediated GSDMD/E activation and pyroptosis in influenza A virus-infected airway epithelial cells.
Article in iScience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Pyroptosis plays an important role in attracting innate immune cells to eliminate infected niches. Our study focuses on how influenza A virus (IAV) infection triggers pyroptosis in respiratory epithelial cells. Here, we report that IAV infection induces pyroptosis in a human and murine airway epithelial cell line. Mechanistically, IAV infection activates caspase-8 and caspase-3, which cleave and activate gasdermin (GSDM) D and GSDME, respectively. Z-nucleic acid-binding protein 1 (ZBP1) and receptor-interacting protein kinase (RIPK) 1 activity but not RIPK3 are required for caspase-8/3 and GSDMD/E activation and pyroptosis. GSDMD/E, ZBP1, and RIPK1 knockout all block IAV-induced pyroptosis but enhance virus replication. Transforming growth factor β-activated kinase 1 (TAK1) activation via the adaptor protein TRIF suppresses RIPK1, caspase-8/3, and GSDMD/E activation and pyroptosis. The TAK1 inhibitor 5Z-oxzeneonal (5Z) enhances IAV-induced caspase-8/3 and GSDMD/E cleavage in the lung tissues of IAV-infected mice. Our study unveils a previously unrecognized mechanism of regulation of IAV-induced pyroptosis in respiratory epithelial cells.
