Vagal TRPV1 <sup>+</sup> sensory neurons protect against influenza virus infection by regulating lung myeloid cell dynamics
Bibliographic record
Abstract
Influenza viruses are a major global cause of morbidity and mortality. Although vagal TRPV1 + nociceptive sensory neurons are known to mediate defenses against harmful agents, including pathogens, their function in lung antiviral defenses remains unclear. Our study demonstrates that both systemic and vagal-specific ablation of TRPV1 + nociceptors reduce survival in mice infected with influenza A virus (IAV). Despite no difference in viral load, mice lacking TRPV1 + neurons exhibited increased viral spread, exacerbated lung pathology, and elevated levels of proinflammatory cytokines. Loss of TRPV1 + neurons altered the lung immune landscape, including an expansion of neutrophils and monocyte-derived macrophages. Transcriptional analysis revealed impaired interferon signaling in myeloid cells and an imbalance in distinct neutrophil subpopulations in the absence of nociceptors. Furthermore, antibody-mediated depletion of myeloid cells during IAV infection substantially improved survival after nociceptor ablation, underscoring the role of TRPV1 + neurons in preventing pathogenic myeloid cell states that contribute to IAV-induced mortality.

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.
