Abstract
Neutrophils and inflammatory monocytes control sepsis by migration to the site of infection via their chemokine receptors. CCR5 is a chemokine receptor that is not expressed on neutrophils and inflammatory monocytes under homeostatic conditions. However, it has been demonstrated that CCR5 can become expressed on these cells during different models of inflammation. In the present study, we investigated if CCR5 is also expressed on neutrophil and inflammatory monocytes during sepsis, exerting an important role in the migration of these cells to the infectious focus. Using cecal ligation and puncture model to induce polymicrobial sepsis, we demonstrated that the expression of CCR5 is induced on CD11bLy6GLy6C inflammatory monocytes, but not on neutrophils (CD11bLy6GLy6C). Furthermore, CCR5 plays an important role for the migration of the inflammatory monocytes to infection focus during sepsis. CCR5-expressing inflammatory monocytes migrate from the bone marrow to the circulation and then into the site of infection, where they phagocytize and kill the bacteria. Consequently, CCR5 mice showed increased systemic inflammatory response and mortality compared to wild-type mice. These data therefore demonstrate a hitherto unrecognized protective role of CCR5 in sepsis.

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
