T-2 toxin-induced splenic injury by disrupting the gut microbiota-spleen axis via promoting IL-6/JAK/STAT1 signaling-mediated inflammation and apoptosis and its mitigation by elemental nano-selenium.

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
T-2 toxin is one of the most toxic A trichothecene mycotoxins prevalent in the environment and food chain, which brings severe health hazards to both animals and humans and it can significantly damage immune function. In this study, we comprehensively explained the impact of T-2 toxin on the spleen through gut microbiota-spleen axis by integrating the transcriptome and microbiome. Our results revealed that dietary T-2 toxin ≥ 1.0 mg/kg exposure significantly inhibited the growth performance and caused spleen injury in broilers chicks, accompanied by oxidative stress and histopathological damage. Cecal microbiome analysis suggested that T-2 toxin exposure caused gut microbial dysbiosis, especially leading to the decrease of some beneficial bacteria genera that enhanced gut barrier and reduced inflammation, including Blautia, Coprococcus, Lachnospira and Anaerostipes belonging to Lachnospiraceae family. Transcriptome analysis suggested that T-2 toxin exposure directly caused splenic inflammation and immune-related signaling, such as cytokine-cytokine receptor interaction, Toll-like receptor signaling pathway, NOD-like receptor signaling pathway and JAK-STAT signaling pathway. Furthermore, by integrating the transcriptome and microbiome analysis, we found that spleen damage induced by T-2 toxin was associated with the abnormal activation of IL-6/JAK/STAT1 signaling pathway-mediated inflammation and apoptosis, which was further verified by western bolt analysis. Notably, dietary selenium supplementation could protect chicks from T-2 toxin-induced adverse effects on growth performance and spleen injury by inhibiting the expression of the IL-6/JAK/STAT1 signaling-related genes. In summary, our findings provided new insights into the immunotoxicity mechanisms of T-2 toxin in the chickens' spleen and highlighted the potential of selenium to alleviate T-2 toxin-induced immunotoxicity.
