Abstract
Activation of naive T cells by antigen requires signaling via the T-cell receptor (TCR) and co-stimulatory receptors. However, in response to homeostatic pressure, T lymphocytes undergo cytokine-driven proliferation without overt antigen stimulation. Homeostatic expansion is more pronounced in the CD8+ T-cell compartment, with memory CD8+ T cells showing intense proliferation resulting from increased responsiveness to IL-15. On the other hand, naive CD8+ T cells require IL-7 and MHC-I to undergo homeostatic expansion, implying the requirement for a basal level of TCR signaling. Probably because of this strict requirement for MHC, earlier reports on antigen-independent stimulation of naive human CD8+ T cells by inflammatory cytokines did not receive much attention. Recently, we and others have shown that naive murine CD8+ T cells undergo proliferation following synergistic simulation by inflammatory cytokines. Such cytokine-driven, antigen-independent activation also "sensitizes" or "primes" naive CD8+ T cells, enabling them to respond robustly to limiting concentrations of cognate antigens, produce effector cytokines abundantly, and display potent cytolytic activity. We propose that cytokine synergy, which induces antigen-independent activation and priming of naive CD8+ T cells, may significantly contribute to the transition from innate to adaptive immune response and to inadvertent activation of autoreactive CD8+ T 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
