Cellular Interactions in Vitro: Psoriatic Keratinocytes Enhance T Lymphocyte Survival
Bibliographic record
Abstract
Background The pathogenesis of psoriasis vulgaris is attributed to an immune dysregulation of T lymphocytes, and psoriatic plaques result from interactions between keratinocytes and T lymphocytes. Objective To decipher the impact of keratinocyte-T lymphocyte interactions on cell survival during active cutaneous psoriasis by using a new in vitro model of psoriasis. Methods Cocultures of psoriatic or healthy keratinocytes were performed with normal human blood T lymphocytes. Apoptosis was detected by flow cytometry after labeling cells with annexin V and propidium iodide. Results Psoriatic keratinocytes were significantly more efficient than healthy keratinocytes in enhancing T lymphocyte survival. Conclusion Our in vitro model is pertinent to understanding the immunopathogenesis of psoriasis and to discovering new pharmacological targets.

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.
