Ionized calcium‐binding adaptor molecule 1 positive macrophages and HO‐1 up‐regulation in intestinal muscularis resident macrophages
Bibliographic record
Abstract
ABSTRACT Small intestinal muscularis externa macrophages have been associated with interstitial cells of Cajal. They have been proposed to play various roles in motility disorders and to take part in a microbiota‐driven regulation of gastrointestinal motility. Our objective was to understand the reaction of resident macrophages of the musculature to a pro‐inflammatory stimulator, lipopolysaccharide (LPS). Mice were injected with LPS or saline and sacrificed after 6 hr. Whole mounts were stained with antibodies toward CD169, ionized calcium‐binding adaptor molecule 1 (iba1) (microglial/macrophage marker) and heme oxygenase‐1 (HO‐1). Cell densities were measured using unbiased stereology. Results: iba1 pos cells showed an overall higher density than CD169 pos and HO‐1 pos cells. Most HO‐1 pos and iba1 pos cells were positive for CD 169 in serosa and at Auerbach's plexus (AP). At the deep muscular plexus, mainly iba1 pos cells were present, and were mostly CD169 neg ; a few HO‐1 pos cells were present. Conclusions: A new subset of resident macrophages in the intestinal muscularis externa was discovered, identified as iba1 pos CD169 neg . HO‐1 is constitutively present in most macrophages in serosa and at AP, suggesting a M2 phenotype. LPS‐treatment results in an up‐regulation of HO‐1 pos /CD169 neg cells in serosa and at AP.

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.
