The Potential of CpG Oligodeoxynucleotides as Mucosal Adjuvants
Bibliographic record
Abstract
The development of mucosal vaccines for humans has been hindered by the lack of safe yet effective mucosal adjuvants. Bacterial toxins are commonly used as adjuvants in animal models, but they are too toxic for use in humans. A novel class of adjuvant is CpG DNA, which contains unmethylated CpG dinucleotides in particular base contexts (CpG motifs). CpG DNA is most often coadministered with antigen in the form of synthetic oligodeoxynucleotides (CpG ODN), which are made with a nuclease-resistant phosphorothioate backbone. The vast majority of studies using CpG DNA as adjuvant have been with parenteral delivery; recently, however, mucosal immunization with CpG DNA as adjuvant has also been shown to induce both systemic (humoral and cellular) and mucosal antigen-specific immune responses. This review will highlight the recent uses of CpG DNA as an adjuvant at mucosal surfaces.

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.
