Interferon and Antiallergic Drug Regulation of Histamine and Tumor Necrosis Factor-α in Rat Mast Cell Subsets
Bibliographic record
Abstract
We have further characterized the heterogeneity of mast cells (MCs) by comparing the ability of rat peritoneal MCs (PMCs) and intestinal mucosal MCs (IMMCs) to produce tumor necrosis factor (TNF)-alpha and by investigating its regulation by interferon (IFN) and the antiallergic drugs nedocromil sodium (NED) and sodium cromoglycate (SCG). Although IMMCs store less TNF-alpha than PMCs, they produced comparable amounts of TNF-alpha in cytotoxic assays. Just as SCG and NED inhibit histamine secretion from PMCs but not IMMCs, IFN exhibited a similar differential effect on histamine release from these cells. However, SCG, NED, and IFN inhibit TNF-alpha-dependent cytotoxicity by both PMCs and IMMCs and reduce the steady-state levels of mRNA for TNF-alpha in PMCs. Thus, the modulation of MC mediator release depends upon the MC population and mediator studied. The inhibitory effect of SCG and NED on TNF-alpha release from MCs may explain some of their anti-inflammatory and therapeutic effects.

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.
