Abstract
Dilated cardiomyopathy, resulting from myocarditis, is the most common cause of heart failure in young patients. We here show that interleukin (IL)-1 receptor type 1-deficient (IL-1R1(-/-)) mice are protected from development of autoimmune myocarditis after immunization with alpha-myosin-peptide(614-629). CD4(+) T cells from immunized IL-1R1(-/-) mice proliferated poorly and failed to transfer disease after injection into naive severe combined immunodeficiency (SCID) mice. In vitro stimulation experiments suggested that the function of IL-1R1(-/-)CD4(+) T cells was not intrinsically defect, but their activation by dendritic cells was impaired in IL-1R1(-/-) mice. Accordingly, production of tumor necrosis factor (TNF)-alpha, IL-1, IL-6, and IL-12p70 was reduced in dendritic cells lacking the IL-1 receptor type 1. In fact, injection of immature, antigen-loaded IL-1R1(+/+) but not IL-1R1(-/-) dendritic cells into IL-1R1(-/-) mice fully restored disease susceptibility by rendering IL-1R1(-/-) CD4(+) T cells pathogenic. Thus, IL-1R1 triggering is required for efficient activation of dendritic cells, which is in turn a prerequisite for induction of autoreactive CD4(+) T cells and autoimmunity.

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
