Re-Engineered Pseudoviruses for Precise and Robust 3D Mapping of Viral Infection.
Article in ACS nano, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Engineered vesicular stomatitis virus (VSV) pseudotyping offers an essential method for exploring virus-cell interactions, particularly for viruses that require high biosafety levels. Although this approach has been employed effectively, the current methodologies for virus visualization and labeling can interfere with infectivity and lead to misinterpretation of results. In this study, we introduce an innovative approach combining genetic code expansion (GCE) and click chemistry with pseudotyped VSV to produce highly fluorescent and infectious pseudoviruses (clickVSVs). These clickVSVs enable robust and precise virus-cell interaction studies without compromising the biological function of the viral surface proteins. We evaluated this approach by generating VSVs bearing a unique chemical handle for click labeling and assessing the infectivity in relevant cell lines. Our results demonstrate that clickVSVs maintain their infectivity post-labeling and present an efficiency about two times higher in detecting surface proteins compared to classical immunolabeling. The utilization of clickVSVs further allowed us to visualize and track 3D virus binding and infection in living cells, offering enhanced observation of virus-host interactions. Thus, clickVSVs provide an efficient alternative for virus-associated research under the standard biosafety levels.
