CD2 costimulation strength: A key regulator of T cell function and anti-tumor immunity that is epigenetically regulated
Bibliographic record
Abstract
tumor-infiltrating T cells from human brain tumors. To identify factors sustaining CD2 expression, we performed a genome-wide CRISPR-Cas9 screen in Jurkat T cells and discovered BAP1 and SUZ12 as regulators. Loss of BAP1 caused downregulation of CD2, TRAC, and other costimulatory receptors, with CD2 and TRAC expression remaining impaired even after activation. Transcriptomic analysis linked BAP1 deficiency to the disruption of programs controlling T cell identity and differentiation, while histone deacetylase inhibition partially restored CD2. In primary human T cells, reduced CD2 costimulation impaired the magnitude of proliferation and IFN-γ production. These findings identify BAP1 as a central regulator of receptor expression and highlight CD2 as a tunable modulator of human T cell responses.

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.
