Restriction of Viral Replication, Rather than T Cell Immunopathology, Drives Lethality in Murine Norovirus CR6-Infected STAT1-Deficient Mice
Bibliographic record
Abstract
The intestinal microbiota is a collection of bacteria, archaea, fungi, and viruses that colonize the mammalian gut. Coevolution of the host and microbiota has required development of immunological tolerance to prevent ongoing inflammatory responses against intestinal microbes. Breakdown of tolerance to bacterial components of the microbiota can contribute to immune activation and inflammatory disease. However, the mechanisms that are necessary to maintain tolerance to viral components of the microbiome, and the consequences of loss of tolerance, are less well understood. Here, we show that STAT1 is integral for preventing escape of a commensal-like virus, murine norovirus CR6 (MNV CR6), from the gut and that in the absence of STAT1, mice succumb to infection-induced disease. In contrast to the case with other systemic viral infections, mortality of STAT1-deficient mice is not driven by immune-mediated pathology. Our data demonstrate the importance of host-mediated geographical restriction of commensal-like viruses.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
