1 · What the graph read from it

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.

2 · The registry

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

backgroundExtracellular vesicles (EVs) play a pivotal role in host-parasite interactions, particularly in facilitating parasite pathogenesis and immune modulation, and are crucial mediators of intercellular communication. Theileria annulata, an apicomplexan parasite, induces severe alterations in host cells, promoting uncontrolled proliferation, resistance to apoptosis, and immune evasion. Although EVs contribute to these processes, the proteins and small RNA cargo involved in T. annulata infection remain incompletely characterized. In particular, little is known about EV profiles in infections caused by drug-resistant field strains.

methodsIn this study, we conducted systematic proteomic and small RNA profiling of EVs derived from naturally occurring buparvaquone-resistant T. annulata (Xinjiang Kashi strain) infected and uninfected bovine sera to investigate infection-induced alterations. Additionally, EVs were isolated from T. annulata-infected bovine immune cells to determine the protein and microRNA (miRNA) compositions of EVs secreted by specific immune cell types. Label-free liquid chromatography-tandem mass spectrometry proteomics and small RNA sequencing were employed to identify EV-associated proteins and miRNAs, followed by functional enrichment analysis to explore key host-parasite regulatory pathways.

resultsOur analysis identified 2580 proteins and 6635 miRNAs in EVs derived from T. annulata-infected bovine serum and immune cell types, many of which are implicated in parasite development, host invasion, and immune modulation. Significant alterations were observed in the EV cargo from infected sera, including enrichment of vesicular proteins and miRNAs associated with immune regulation, metabolic reprogramming, and host-pathogen interactions. Furthermore, functional enrichment analyses highlighted key pathways such as ECM-receptor interactions, oxidative phosphorylation, and proton transport, underscoring the role of EVs in host immune modulation. Supplementary analysis of EVs from infected immune cells provided further insights into the cell type-specific contributions.

conclusionsThis study comprehensively characterized the infection-induced changes in serum-derived EVs associated with a naturally occurring buparvaquone-resistant T. annulata infection. It offers novel insights into how T. annulata exploits EVs to manipulate host responses. The identification of unique EV-associated proteins and miRNAs highlights their potential as biomarkers and therapeutic targets for Theileria infections. These findings contribute to a deeper understanding of host-parasite interactions and lay the foundation for future investigations into EV-mediated pathogenesis and immune evasion.
