AexB is an aromatic amino acid exporter that functions as a metabolic safety valve.
Article in mBio, 2026. 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
Aromatic amino acids-tryptophan, tyrosine, phenylalanine, and histidine-are essential for bacterial growth and are among the most energetically expensive metabolites to synthesize. Despite this cost, it has been recently shown that bacteria possess exporters for these amino acids. Here, we identify IMPORTANCE: Identification and characterization of amino acid exporters is a broadly relevant topic. Amino acid synthesis is energetically costly, and thus functional relevance for their export is unintuitive. Identification of the molecular components that allow export may offer new engineering opportunities to improve biomanufacturing and metabolic engineering. Characterization of these exporters may also provide a more complete understanding of the human microbiome where amino acids, especially tryptophan, have been established as nodes of crosstalk between host and microbiota.
