Abstract
There is growing interest in the fundamental roles that B cells may play in regulating immune responses. Emerging animal studies point to an important contribution of B cell effector cytokines to immune modulation, yet little is known about the factors regulating such cytokine production. We report that the profile of human B cell cytokine production is context dependent, being critically influenced by the balance of signals through the B cell receptor and CD40. B cells appropriately stimulated by sequential B cell receptor and CD40 stimulation proliferate and secrete TNF-alpha, lymphotoxin, and IL-6, which can act not only as autocrine growth and differentiation factors, but also serve to amplify the ongoing immune response. In contrast, CD40 stimulation alone, a mimic of a B cell receiving bystander T cell help in the absence of specific Ag recognition, induces negligible proinflammatory cytokines, but significant production of IL-10 that serves to suppress inappropriate immune responses. We thus describe a novel paradigm of reciprocal regulation of B cell effector cytokines, and ascribe active roles for human B cells in either promoting or suppressing local immune responses through context-dependent cytokine production.

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
