Multi-omics analysis identifies a microbiota-bile acid-TLR signaling axis driving bladder injury in interstitial cystitis.
Article in Nature communications, 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
Hunner-type interstitial cystitis/bladder pain syndrome (HIC) is a debilitating condition defined by bladder pain and urinary urgency, yet its upstream drivers remain poorly understood. To identify upstream mechanisms that exacerbate urothelial injury, here we apply an integrative multi-omics framework combining metagenomic sequencing, targeted metabolomics of urine and serum, and single-cell RNA sequencing. This approach reveals a microbial signature enriched in Enterococcus avium and a marked alteration in bile acid metabolism, including increased taurochenodeoxycholic acid (TCDCA). Single-cell analysis indicates that these changes converge on Toll-like receptor 3 (TLR3) activation in urothelial cells. Further validations show that a microbiota-bile acid-TLR3 axis disrupts epithelial barrier integrity and triggers inflammatory responses in experimental models. Transplantation and metabolite administration confirm the causal role of E. avium and TCDCA, while TLR3 inhibition ameliorates injury. These findings uncover an upstream pathway linking gut-derived metabolites to bladder pathology and suggest opportunities for biomarker development and targeted therapies for HIC.
