Abstract
Expression of the Jagged Notch ligands by dendritic cells (DCs) has been suggested to play a role in instructing Th2 responses. Supporting this hypothesis, we found that Jagged2 but not Jagged1 expression, correlates with the ability of DCs to induce Th2 responses. Jagged2 expression is up-regulated in response to the helminth soluble Schistosoma mansoni egg Ag, which conditions DCs to induce Th2 responses, and is markedly down-regulated following exposure to TLR agonists that generally promote Th1 responses. Conversely, Jagged1 expression is markedly induced by TLR ligation. Despite these correlations, suppression of expression of Jagged2 using retrovirally delivered small interfering RNA failed to affect the ability of DCs to induce Th2 cell differentiation either in vitro or in vivo. Moreover, retrovirally induced expression of Jagged2 did not enhance the ability of DCs to induce Th2 cell responses. Our data indicate that Jagged2 expression by DCs is not sufficient or required for Th2 cell differentiation.

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
