Suppression of Reaginic Antibodies with Modified Allergens
Bibliographic record
Abstract
Administration of multiple injections of conjugates of ovalbumin (OA) and polyethylene glycol (PEG) or its monomethoxy derivative (mPEG) into mice which had been sensitized with 2,4-dinitrophenylated OA (DNP<sub>3</sub>–OA) abrogated both the anti-OA and anti-DNP IgE responses, in spite of additional injections of the sensitizing dose of DNP<sub>3</sub>-OA in the presence of Al(OH)<sub>3</sub>. Treatment of mice with OA-PEG in Al(OH)<sub>3</sub> stimulated preferentially helper T cells, whereas injection of mice with OA-PEG in the absence of adjuvant elicited predominantly suppressor T cells. The unresponsive state of mice which had been treated 21 days earlier with OA-PEG could not be broken by the transfer of normal spleen cells and an additional sensitizing dose of DNP<sub>3</sub>-OA. Transfer of spleen cells from tolerized animals to normal mice dampened the capacity of the latter to mount both anti-DNP and anti-OA IgE responses; however, the suppressive effect of these cells was eliminated by treatment of the normal recipients with cyclophosphamide, which is a procedure known to inactive suppressor T cells, and hence it may be concluded that this effect was not due to the carryover of the tolerogen with the transferred cells. All these results provide strong support for the conclusion that the suppressor cells induced by the treatment of mice with OA-PEG and OA-mPEG conjugates belonged to a T cell subpopulation, and that the B cells of these mice were devoid of suppressive activity.

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.
