Antigen-, Anti-F(ab') <sub>2</sub> - and Anti-IgE-Induced Histamine Release from Rat Mast Cells
Bibliographic record
Abstract
The existence of IgE antibody molecules on peritoneal mast cells from rats immunized with dinitrophenylated ascaris extract was demonstrated by double antibody immunofluorescence staining and by histamine release induced by anti-IgE antibodies. Cross-linking of the IgE molecules, which are fixed to mast cells, by interaction with either the homologous antigen or with antibodies to the Fab or Fc regions of IgE, triggered in the presence of calcium ions a chain of intracellular reactions which involve cyclic nucleotide modulation and energy-requiring processes leading ultimately to the release of histamine from the granules of these cells. Although there was no apparent difference in the mechanism(s) underlying the reactions triggered by any of these three agents, the extent of histamine release caused by antibodies to the Fc region of the IgE was significantly lower than that induced by cross-linking of IgE molecules through their Fab regions by reactions with either anti-Fab antibodies or antigens.

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.
