Identification of an IRF8 gene in common carp (Cyprinus carpio. L) and its regulatory role in immune responses.
Article in BMC veterinary research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundInterferon (IFN) regulatory factors (IRF) are the crucial transcription factors for IFN expression and leading host cells response to viral infection. IRF8 in mammals plays vital roles in the innate and adaptive immune systems. In this study, we identified and characterized the common carp (Cyprinus carpio. L) IRF8 gene (ccIRF8) to further clarify the function of IRF8 in teleost fish.
resultsThe complete cDNA sequence of ccIRF8 was 1431 bp and encodes a polypeptide of 431 amino acids. Analysis of the putative amino acid sequence showed that ccIRF8 encodes structures typical of the IRF family, including a DNA-binding domain (DBD), an IRF-association domain (IAD) and two nuclear localization signals (NLS). Comparison with homologous proteins showed that the deduced protein has the highest sequence identity to grass carp IRF8 (92.7%). Phylogenetic analysis grouped ccIRF8 with other IRF8s of teleosts. Quantitative RT-PCR analysis showed that ccIRF8 transcripts were detectable in all investigated tissues of healthy fish with the highest level in spleen. Following poly I: C and Aeromonas hydrophila challenge, ccIRF8 transcripts were induced significantly in immune relevant tissues. In addition, ccIRF8 was induced by poly I: C and ipopolysaccharide (LPS), peptidoglycan (PGN) and flagellin in HKLs. Overexpression of ccIRF8 increased the expression of IFN and IFN-stimulated genes (ISGs), and a dual-luciferase reporter assay revealed that ccIRF8 decreased the activation of NF-κB though TRAF6.
conclusionsOverall, our findings provide a new perspective on the role of IRF8 in innate immunity in fish, as well as insights that will help the prevention and control of disease in the common carp farming industry.
