Abstract
Retinoic acid (RA) is produced by a number of cell types, including macrophages and dendritic cells, which express retinal dehydrogenases that convert vitamin A to its main biologically active metabolite, all-trans RA. All-trans RA binds to its nuclear retinoic acid receptors that are expressed in lymphoid cells and act as transcription factors to regulate cell homing and differentiation. RA production by CD103(+) dendritic cells and alveolar macrophages functions with TGF-β to promote conversion of naive T cells into Foxp3(+) regulatory T cells and, thereby, maintain mucosal tolerance. Furthermore, RA inhibits the differentiation of naive T cells into Th17 cells. However, Th1 and Th17 responses are constrained during vitamin A deficiency and in nuclear RA receptor α-defective mice. Furthermore, RA promotes effector T cell responses during infection or autoimmune diseases. Thus, RA plays a role in immune homeostasis in the steady-state but activates pathogenic T cells in conditions of inflammation.

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
