Abstract
Plasmid DNA continues to attract interest as a potential vaccine-delivery vehicle. However, the mechanisms whereby immune responses are elicited by plasmids are not fully understood. Although there have been suggestions regarding the importance of CpG motifs in plasmid immunogenicity, the molecular mechanisms by which CpG motifs enhance immune responses to DNA vaccines are not well understood. As Toll-like receptor 9-deficient (TLR9-/-) mice fail to respond to the adjuvant effects of CpG oligonucleotides, we used these mice to determine the effect of CpG motifs in plasmids used for DNA immunization. In the study described below, we report that DNA immunization was as effective in eliciting antigen-specific antibody and at stimulating antigen-specific interferon-gamma (IFN-gamma)-secreting cells in TLR9-/- mice as in TLR9+/+ mice. This study illustrates that DNA vaccines elicit immune responses by multiple mechanisms and demonstrates that TLR9 is not essential for the induction of immune responses following DNA immunization.

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 it
