Sources of essential lipids for Mycoplasma pneumoniae via P116 to target liver and atherosclerotic lesions.
Article in Nature communications, 2025. 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
Mycoplasma pneumoniae (MPN) is a bacterial pathogen that primarily causes atypical pneumonia. It cannot synthesize certain essential lipids and therefore relies on the host for their acquisition to survive. MPN has been detected in increased amounts within ruptured atherosclerotic plaques. In this work, we show that the protein P116 facilitates cholesterol acquisition from LDL, HDL and various cell types. Targeting P116's C-terminal domain with a monoclonal antibody inhibits cholesterol acquisition and bacterial growth in vitro. Phase contrast epifluorescence microscopy of human arteries reveals that this antibody blocks MPN binding to atherosclerotic lesions ex vivo. Additionally, an MPN chassis injected into hyperlipidemic female mice localizes to the liver and atherosclerotic plaques. Here, we report that P116 plays a role in extracting essential lipids from lipoproteins and host cells and regulates MPN localization to atheromatous plaques. The study highlights MPN's potential as a tool for targeting atherosclerotic lesions and fatty liver.
