Abstract
Monocytes are central to the physiopathology of arthritis, but their roles in progression and resolution of the disease remain to be clarified. Using NR4A1 −/− mice, which lack patrolling lymphocyte antigen 6C (Ly6C low ) monocytes, we found that inflammatory Ly6C high monocytes contribute to rapid development of arthritis in a serum transfer‐induced arthritis (STIA) model. Our experiments suggest that patrolling monocytes do not promote the initiation and progression of arthritis in mice, as severity of symptoms was amplified in NR4A1 −/− mice. Moreover, we show that treatment of arthritic wild type (WT) mice with cytosporone B (Csn‐B), a NR4A1‐specific agonist, significantly reduces severity of disease. Effects of Csn‐B were absent in monocyte‐depleted mice treated with clodronate until Ly6C low monocytes were restored. Adoptive transfer of Ly6C low monocytes in arthritic NR4A1 −/− mice treated with Csn‐B reduces joint inflammation, supporting the regulatory role of Ly6C low subset on disease development. Our results also reveal that administration of Csn‐B to arthritic mice enhances levels of circulating CD4 + CD25 + FoxP3 + Treg cells, a process requiring the presence of Ly6C low monocytes. Together, these data indicate that Ly6C high monocytes are involved in the initiation and progression of arthritis and Ly6C low monocytes contribute to reduce joint inflammation through the mobilization of Treg cells.

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
