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: iba1pos cells showed an overall higher density than CD169pos and HO‐1pos cells. Most HO‐1pos and iba1pos cells were positive for CD 169 in serosa and at Auerbach's plexus (AP). At the deep muscular plexus, mainly iba1pos cells were present, and were mostly CD169neg; a few HO‐1pos cells were present. Conclusions: A new subset of resident macrophages in the intestinal muscularis externa was discovered, identified as iba1pos CD169neg. 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‐1pos/CD169neg cells in serosa and at AP.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
