The Porcine Cyclic GMP-AMP Synthase-STING Pathway Exerts an Unusual Antiviral Function Independent of Interferon and Autophagy
Bibliographic record
Abstract
The IFN-independent antiviral function of the cGAS-STING pathway has attracted great attention in recent years; however, the nature of this IFN-independent antiviral function is unknown, although STING-induced autophagy has been shown to mediate the STING antiviral activity. First, we analyzed the antiviral activity through the porcine cGAS-pSTING pathway and established that pSTING signaling exerts an IFN-independent antiviral function. Second, we found that pSTING-induced IFN-independent autophagy and the antiviral activity of pSTING are independent of both IFN and autophagy. Finally, pSTING signaling activates cell apoptosis independently of IFN and autophagy, and the apoptosis is associated with antiviral activity. Our results suggest that pSTING-activated apoptosis at least partially mediates the antiviral activity or multiple pSTING-activated signals, including IFN production, nuclear factor κ light chain enhancer of activated B cells (NF-κB) expression, autophagy, and apoptosis, exert a redundant antiviral role. Thus, the work reveals a new layer of complexity in STING antiviral activity.

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.
