Polybacterial intracellular macromolecules shape single-cell inflammatory profiles in upper airway epithelia.
Article in NPJ biofilms and microbiomes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Mucosal epithelial cells of the upper airways are continuously exposed to microbes throughout life. Specialized niches such as the anterior nares and the tooth are especially susceptible to dysbiosis and chronic inflammatory diseases. Here, we reanalyzed our v1-Human Periodontal Atlas, identifying polybacterial signatures (20% Gram-positive; 80% Gram-negative) and distinct responses of bacterial-associated epithelia. Fluorescence microscopy detected numerous persistent polybacterial intracellular macromolecules (PIMs) within human oral keratinocytes (HOKs), including bacterial rRNA, mRNA, and glycolipids. PIM levels directly correlated with enhanced receptor-ligand signaling in vivo. Inflammatory "keratokines" targeting immune cells were synergistically upregulated in lipopolysaccharide-challenged HOKs, while endogenous lipoteichoic acid (LTA) correlated with CXCL1/8 expression in vitro and in vivo. Application of Drug2Cell suggested altered drug efficacy predictions based on PIM detection-agnostic of disease state. CXCL1/8 expression again correlated with LTA in epithelial cells of the nasal cavity, oropharynx, and trachea. Thus, PIMs shape epithelial single-cell profiles across upper airway mucosae.
