Cultured <scp>CD71</scp><sup>+</sup> erythroid cells modulate the host immune response
Bibliographic record
Abstract
Abstract Objective The study aimed to determine the impact of Red Blood Cells (RBCs) generated from peripheral blood mononuclear cells (PBMCs) on T cell proliferation and host response following whole blood stimulation. Background Culturing RBCs is a potential solution for donor shortage. The impact of immature cultured RBCs which express CD71 + on host immune response is not known. Methods/Materials PBMCs were seeded in an erythroid expansion medium. CD71 + cells were isolated at days 14 and 21 of culture and incubated with either purified T cells or with LPS‐stimulated whole blood. Controls were incubated with medium. Results At day 9, the percentage of cells that expressed CD45 and CD71 reached to the highest level (32.9%, IQR; 26.2–39.05) while the percentage of cells that expressed CD71 and CD235a reached to the highest level on day 17 (70.2%, IQR; 66.1–72.8). Incubation of T cells with days 14 CD71 + cells and day 21 CD71 + cells increased T cell proliferation. In a whole blood stimulation assay, day 21 CD71 + cells, but not day 14 CD71 + cells, inhibited the production of IL‐6 and TNFα. Conclusion Cultured erythroid cells can modulate the immune response by promoting T cell proliferation and inhibiting cytokine secretions following whole blood stimulation.

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; both teacher heads agree on what is shown here.
