Cutaneous GVHD is associated with the expansion of tissue-localized Th1 and not Th17 cells
Bibliographic record
Abstract
Studies in mice have shown that proinflammatory Th17 cells can cause acute graft-versus-host disease (aGVHD) related tissue damage; however, whether they play a role in human aGVHD remains unclear. In a prospective study, we measured the proportion of Th17 cells in the blood and skin of patients at the onset of aGVHD. We found no difference in the proportion or amount of IL-17 produced by T cells in the blood of patients with aGVHD (n = 20) compared with time-matched patients without GVHD (n = 14). Moreover, Th17 cells were not increased in the skin of patients with cutaneous aGVHD (n = 7) compared with healthy controls (n = 10). In contrast, we found significantly more interferon-γ-producing T cells in the skin of patients with aGVHD compared with controls. These data support the long-standing paradigm that tissue localized interferon-γ-producing cells are the perpetrators of aGVHD.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
