Toso regulates the balance between apoptotic and nonapoptotic death receptor signaling by facilitating RIP1 ubiquitination
Bibliographic record
Abstract
The regulation of cellular survival and apoptosis is of critical importance for the immune system to maintain immune homeostasis and to establish tolerance. Here, we demonstrate that the immune specific cell surface molecule Toso exhibits antiapoptotic effects on death receptor signaling by a novel regulatory mechanism involving the adaptor kinase RIP1. The antiapoptotic function of Toso depends on RIP1 ubiquitination and involves the recruitment of the death adaptor FADD to a Toso/RIP1 protein complex. In response to CD95L and TNFα, Toso promotes the activation of MAPK and NF-κB signaling pathways. Because of this relative augmentation of survival versus apoptotic signals, Toso raises the threshold for death receptor-mediated apoptosis. Our analysis of Toso-deficient mice revealed that Toso is essential for TNFα-mediated liver damage. Furthermore, the antiapoptotic function of Toso could be blocked by a Toso-specific monoclonal antibody, opening up new therapeutic prospects for the treatment of immune disorders and hematologic malignancies.

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.
