Cutting Edge: Profound Defect in T Cell Responses in TNF Receptor-Associated Factor 2 Dominant Negative Mice
Bibliographic record
Abstract
TNFR-associated factor 2 (TRAF2) is an adapter protein that links several members of the TNFR family to downstream signaling pathways. Mice expressing a dominant negative form of TRAF2 in their lymphoid cells (TRAF2.DN mice) have a profound defect in T cell responses to allogeneic APC. In contrast, APC from wild-type or TRAF2.DN mice show an equivalent level of stimulation in a MLR. Ab production and class switch are unimpaired in TRAF2.DN mice. Thus, defects in the TRAF.DN mice appear to be limited to T cells. TRAF2.DN mice demonstrate an impaired T cell response to influenza virus, including decreased secondary expansion of IFN-gamma-secreting T cells as well as a decrease in CTL activity. CD4 T cell production of IL-2 was also dramatically impaired in TRAF2.DN mice. These studies suggest an essential role of TRAF2-linked receptors in secondary CD4 and CD8 T cell responses and have important implications for transplantation.

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.
