Abstract
The long term goal of immunological therapy for transplantation is to induce antigen specific unresponsiveness. One approach of significant current interest is the induction of T regulatory (Treg) cells that downregulate immune responses in an antigen specific manner. In this study, we examined the nature of the immunological regulation initiated by oral exposure to alloantigen. We previously demonstrated that feeding of allogeneic donor splenocytes significantly prolongs kidney allograft survival in rats. Purified CD8+ graft infiltrating cells (GIC), but not CD4+ GIC transfer graft prolongation to naïve animals demonstrating the presence of a CD8+ Treg population in the graft. In this study, we provide evidence that is consistent with a hypothesis that the CD8+ Treg generated by oral exposure to alloantigen is an IL-10 secreting, gammadelta TCR+ T cell.

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
