Abstract
Plant exosomes protect plants against infection; however, whether edible plant exosomes can protect mammalian hosts against infection is not known. In this study, we show that ginger exosome-like nanoparticles (GELNs) are selectively taken up by the periodontal pathogen Porphyromonas gingivalis in a GELN phosphatidic acid (PA) dependent manner via interactions with hemin-binding protein 35 (HBP35) on the surface of P. gingivalis. Compared with PA (34:2), PA (34:1) did not interact with HBP35, indicating that the degree of unsaturation of PA plays a critical role in GELN-mediated interaction with HBP35. On binding to HBP35, pathogenic mechanisms of P. gingivalis were significantly reduced following interaction with GELN cargo molecules, including PA and miRs. These cargo molecules interacted with multiple pathogenic factors in the recipient bacteria simultaneously. Using edible plant exosome-like nanoparticles as a potential therapeutic agent to prevent/treat chronic periodontitis was further demonstrated in a mouse model.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
