The role of caspase-1, caspase-4 and NLRP3 in regulating the host cell response evoked by uropathogenic Escherichia coli.
Article in Scientific reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
The inflammasome-associated proteins caspase-1, caspase-4 and NLRP3 have been emphasised to be essential in the host cell response during urinary tract infection (UTI) by regulating IL-1β release. Our aim was to investigate how the inflammasome-associated proteins regulate the cell response of bladder epithelial cells during infection with uropathogenic Escherichia coli (UPEC). Human bladder epithelial cells (5637) and CRISPR/Cas9 generated caspase-1, caspase-4 and NLRP3 knockdown cells were stimulated with the UPEC strain CFT073. Using Olink proteomics and real time RT-PCR, we showed that caspase-1, caspase-4 and NLRP3 are vital for the expression of many inflammatory genes and proteins from bladder epithelial cells. When investigating the effect of inflammasome-associated proteins on neutrophils, we found that conditioned medium from UPEC-infected caspase-4 knockdown cells significantly increased phagocytosis of CFT073 and significantly decreased ROS production from neutrophils. In contrast, conditioned medium from UPEC-infected NLRP3 knockdown cells significantly decreased the phagocytosis of CFT073 and significantly increased the ROS production from neutrophils. In conclusion, we showed that the inflammasome-associated proteins contribute to the host cell response during UPEC infection.
