CD2 and its ligands are involved in development and activation of MAIT cells
Bibliographic record
Abstract
MAIT cells are innate-like T cells known for their semi-invariant TCR that recognizes vitamin B metabolites presented by MR1. While the involvement of TCR and cytokines in development and activation of MAIT cells is well documented, the contribution of co-receptors, including SLAM family receptors, remains poorly understood. This study revealed that CD2 and its ligands, CD48 in mice and CD58 in humans, were crucial for MAIT cell maturation and antigen-driven activation, but not for their responses to cytokines. Cis interactions of CD2 with its ligands on the same cell were essential for activation, with trans interactions contributing in some contexts. A natural subset of human MAIT cells lacking CD2 displayed reduced activation responses to antigen. Human CD48 recognized 2B4 rather than CD2, dampening TCR signal strength and activation of human MAIT cells. Thus, the interplay between CD2 and its ligands is pivotal for MAIT cell development and activation, highlighting potential approaches for treating human diseases implicating MAIT cells.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
