Non-Invasive Immunization on the Skin Using DNA Vaccine
Bibliographic record
Abstract
Skin has evolved to protect not only by acting as a physical barrier, but also by its role in our powerful immune system. As a frontline of the host's defense against pathogens, skin is well equipped for immune surveillance. For example, compared to many other tissues, the epidermis of the skin contains a high population of Langerhans cells, which are very potent immature dendritic cells. Thus, targeting antigens to the skin epidermis should be able to efficiently induce strong immune responses. However, the forbidden barrier posed by the stratum corneum layer of the epidermis prevents effective entrance of antigens into the epidermis. Nevertheless, non-invasive immunization onto the skin has proven in the last several years to be a viable immunization modality. DNA vaccine is a vaccine made of bacterial plasmid DNA encoding an antigen of interest. Upon uptake of the plasmid, host express and process the encoding antigen, and then mount immune responses against it. DNA vaccine is advantageous over many other types of vaccines. The feasibility of non-invasive immunization onto the skin with DNA vaccine has been confirmed. Although the potency of the immune response has proven to be weak, many skin stratum corneum disrupting chemical and physical approaches and DNA vaccine carriers/adjuvants that significantly enhance the resulting immune response have been reported. In addition, research on elucidating the mechanism of immune induction from non-invasively, topically applied DNA vaccine has also been carried out. With further improvement and optimization, non-invasive immunization onto the skin with DNA vaccine should be able to elicit reliable and efficacious immune response to a variety of antigens.

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.
