Novel anti-inflammatory peptide alleviates liver ischemia-reperfusion injury.
Article in Journal of biomedical research, 2024. 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
Ischemia-reperfusion injury (IRI) remains an unavoidable challenge in liver surgery, with macrophages playing a critical role in its pathogenesis. However, the mechanisms by which macrophages regulate the pathogenesis of IRI are not well understood. Through a target-guided screening approach, we identified a small 3 kDa peptide (SjDX5-271) from various schistosome egg-derived peptides that induced M2 macrophage polarization. SjDX5-271 treatment protected mice against liver IRI by promoting M2 macrophage polarization, and this protective effect was abrogated when the macrophages were depleted. Transcriptomic sequencing showed that the TLR signaling pathway was significantly inhibited in macrophages from the SjDX5-271 treatment group. We further identified that SjDX5-271 promoted M2 macrophage polarization by inhibiting the TLR4/MyD88/NF-κB signaling pathway and alleviated hepatic inflammation in liver IRI. Collectively, SjDX5-271 exhibited some promising therapeutic effects in IRI and represented a novel therapeutic approach, potentially applicable to other immune-related diseases. The current study demonstrates the potential of new biologics from the parasite, enhances our understanding of host-parasite interplay, and provides a blueprint for future therapies for immune-related diseases.
