Host Genetic and Adjuvant Factors Influence Epitope Specificity to a Major Recombinant Grass Allergen
Bibliographic record
Abstract
The role of host genetic and adjuvant factors in the induction of immune responses to a major recombinant Kentucky bluegrass allergen was examined utilizing five strains of mice and two different adjuvants. Analysis of the recombinant allergen-specific antibodies induced in these strains indicated that the antibodies of various isotypes were differentially regulated. In terms of IgE antibody response, BDF1 and DBA/2 were characterized as high responder, whereas BALB/C, CBA/J and C57BL/6 were intermediate and SJL was a low responder. In different strains, both dextran sulfate (DS) and complete Freund's adjuvant (CFA), as adjuvants, induced recombinant allergen-specific IgE antibodies of similar titer, however, CFA induced higher IgG2a and lower IgM antibodies compared to DS. Further, analysis of T cell proliferative responses of the splenocytes of different strains demonstrated that these strains varied also in their capacity to respond to synthetic peptides. Furthermore, utilizing a panel of synthetic peptides corresponding to the recombinant allergen, we demonstrated that the antibodies induced by the recombinant allergen with CFA in different strains vary with respect to their epitope specificity. In the BDF1 strain, compared to DS, CFA as adjuvant induced recombinant allergen-specific antibodies of additional peptide specificity. Taken together, these results suggest that both host genetic background and adjuvants govern the fine specificity of antibodies produced against this recombinant Kentucky bluegrass allergen.

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.
