Abstract
Lymphoid differentiation and activation critically depend on cytokine stimulation and the interleukin-7 (IL-7) signaling in particular. Although it has been demonstrated that IL-7 may play a role in natural killer (NK) cell maturation, the effect of IL-7 stimulation on mature human NK cells has not been studied. We, therefore, investigated the expression and functional activity of IL-7Ralpha on mature NK populations from adult blood. In this article, we demonstrate that IL-7Ralpha is specifically expressed in the CD56bright noncytotoxic cytokine-producing NK subset. Importantly, this expression is thymus independent, contrary to what is observed in mice. In addition, we show that IL-7Ralpha is expressed at higher levels on NKG2A+CD56bright NK cells. In contrast to IL-15 stimulation, IL-7 does not increase NK cell cytotoxicity, interferon-gamma production, or the expression of activation markers, indicating that these cytokines play different functions in NK homeostasis and activation. However, IL-7 promotes the survival of the CD56bright NK subset and inhibits apoptosis by increasing BCL2 expression. These data should be taken into account when considering the clinical use of IL-7, particularly after stem cell transplantation.

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
