Abstract
Dendritic cells are among the most potent antigen-presenting cells and are important in the development of both immunity and tolerance. Tolerogenic dendritic cell (Tol-DC) is a key factor in the induction and maintenance of tolerance during transplantation. However, the precise mechanism and direct evidence of in vivo immune modulation remain unclear. In the present study, we identified critical roles of immune modulation on transplant tolerance through interactions between Tol-DCs and regulatory T (Treg) cells. Tol-DCs remained in an immature state and were insensitive to maturation stimuli. Tol-DCs in tolerant recipients heightened the expression of indoleamine 2,3-dioxygenase (IDO) that induced allogeneic T-cell apoptosis. Adoptive transfer of Tol-DCs isolated from primary tolerant recipients resulted in augmentation of CD4(+)CD25(+)CTLA4(+) Treg cells and prolonged graft survival in secondary allogeneic heart transplantation and synergized with Treg cells to induce tolerance in secondary recipients. This study indicates that Tol-DC offers two functions during the process of tolerogenesis: suppression of anti-donor T-cell responses through production of IDO and interaction with Treg cells, which provides a framework for future research into tolerance induction.

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
