Imaging flow cytometry reveals the mechanism of equine arteritis virus entry and internalization.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The process of viral entry into host cells is crucial for the establishment of infection and the determination of viral pathogenicity. A comprehensive understanding of entry pathways is fundamental for the development of novel therapeutic strategies. Standard techniques for investigating viral entry include confocal microscopy and flow cytometry, both of which provide complementary qualitative and quantitative data. Imaging flow cytometry, which integrates the advantages of both methodologies, offers significant potential in virological studies. In this investigation, we employed imaging flow cytometry coupled with immunostaining to monitor the entry of equine arteritis virus EAV into Vero cells via the endosomal trafficking route. Analysis provided an insight into the early infection dynamics across thousands of cells, revealing statistically significant alterations in internalization and uncoating process. Moreover, we evaluated the effectiveness of two inhibitors targeting cellular factors involved in facilitating viral entry: ammonium chloride, which disrupts endocytosis, and camostat mesylate, which inhibits the activity of serine proteases. The results demonstrated a clear distinction between effective and ineffective inhibitors. This study highlighted the potential of imaging flow cytometry to advance the study of viral entry and the evaluation of antiviral agents.
