Elevated monocyte chemoattractant protein‐1 levels following thermal injury precede monocyte recruitment to the wound site and are controlled, in part, by tumor necrosis factor‐α
Bibliographic record
Abstract
In previous studies, mice given a full-thickness scald injury had an influx of neutrophils into the skin that followed a local increase in a neutrophil chemoattractant. Because macrophages are known to infiltrate the wound area after neutrophils and are essential for normal wound repair, studies were designed to characterize the time course of macrophage accumulation in the wound and to identify the factor(s) responsible for this influx. A macrophage infiltrate into the wound was observed at 4 days post-injury and persisted through at least 10 days. This influx was preceded by an initial fourfold increase in dermal monocyte chemoattractant protein-1 levels at 24 hours post-injury (p < 0.05). This elevation in monocyte chemoattractant protein-1 was enhanced at 4 and 10 days postburn resulting in a sixfold increase over baseline (p < 0.01). Levels of tumor necrosis factor-alpha, a proinflammatory cytokine known to induce chemokine production, were elevated at 90 minutes after injury in burn- versus sham-injured groups (p < 0.05). Furthermore, administration of tumor necrosis factor-alpha neutralizing antibody in vivo reduced the dermal levels of monocyte chemoattractant protein-1 seen at 10 days postburn by 57% (p < 0.01); however, macrophage accumulation was not altered. Thus, elevated systemic TNF-alpha levels may influence the local chemokine milieu following burn injury.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
