Abstract
Tumor necrosis factor a (TNFa) has been shown to trigger many signaling pathways.Following oligomerization by TNFa, the receptors TNF-RI and TNF-RI1 associate with adapter molecules via specific protein-protein interactions.The subsequent recruitment of downstream molecules to the receptor complex enables propagation of the TNFa signal.l k o cellular responses to TNFa have been well documented, the induction of cell death and the activation of gene transcription for cell survival.TNFa-induced apoptosis involves the activation of caspase cascades, which culminate in the cleavage of specific cellular substrates to effect cell death.TNFa has also been implicated in various caspase-independent cell death processes.Two transcription factors activated by TNFa are nuclear factor K B (NFKB) and activating protein 1 (AP-1).Pathways that promote the activation of these transcription factors involve signaling molecules such as kinases, phospholipases, and sphingomyelinases.In addition to increased survival (anti-apoptotic) gene expression, NFKB and AP-1 also induce the expression of genes involved in inflammation, cell growth, and signal regulation.The past decade has witnessed the identification of numerous signaling intermediates implicated in T N F a cellular responses.This article reviews the molecular mechanisms of TNFa signal transduction.In particular, pathways involved in cell death and transcription factor activation are discussed.

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 it
