Abstract
Intestinal epithelial cells have been shown to produce IL-1beta in vivo. This gene expression is rapid and precedes most determinants of inflammation, suggesting a pivotal role for IL-1beta in the early events leading to inflammation. To better understand the mechanisms leading to this IL-1beta production, we have developed an in vitro model system employing a nontransformed intestinal epithelial cell line that does not constitutively express IL-1beta. Following detachment, these cells rapidly expressed IL-1beta mRNA. This expression was enhanced, but not induced, by LPS. IL-1beta protein was detected by immunoprecipitation in the culture medium from passaged IEC-18 but not intracellularly, suggesting an efficient secretion of the molecule following induction. Interestingly, culture supernatants from passaged cells were without IL-1 bioactivity, suggesting the presence of an inhibitor as well. RT-PCR and Western blot analysis showed expression of IL-1RII by IEC-18 following detachment, possibly explaining the observed lack of bioactivity. These results indicate a novel pathway for IL-1beta production and suggest that proinflammatory effects of IEC-derived IL-1 may be modulated by the simultaneous production of IL-1 antagonists.

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.
