Comparison of the Specific IgM and IgG Antibody Response in Humans Induced by Antigen (Tetanus Toxoid) or a Polyclonal Activator (EBV) in vitro
Bibliographic record
Abstract
Culture conditions were established for the reproducible induction of specific antibody responses in vitro using peripheral blood lymphocytes from tetanus toxoid (TT) immunized donors. Maximum anti-TT antibody responses (250-350 ng/ml) were detected on day 9 of culture, with optimum quantities of antigen (0.1-1.0 micrograms/ml TT) or Epstein-Barr virus (EBV). The antigen-driven antibody response unlike the EBV-induced polyclonal response was both T-cell and monocyte-dependent. TT stimulated mainly the IgM class of anti-TT antibody whereas EBV stimulated both IgM and IgG. A combination of TT and EBV caused a partially additive IgM response but suppressed the IgG class of anti-TT antibody. Transfer of cells from 9-day EBV-stimulated cultures to fresh cultures suppressed the anti-TT antibody response, possibly due to elevated levels of OKT8+ suppressor/cytotoxic cells found in culture after EBV infection. These results provide a reliable system for studying B-cell regulation in man.

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.
