Abstract
INTRODUCTION: Polymorphisms in the type III interferon IFN-λ3 and the killer cell immunoglobulin-like receptor (KIR) genes controlling the activity of natural killer (NK) cells can predict spontaneous resolution of acute hepatitis C virus (HCV) infection. We hypothesized that IFN-λ3 polymorphism may modulate NK cell function during acute HCV. METHODS: We monitored the plasma levels of type III IFNs in relation to the phenotype and the function of NK cells in a cohort of people who inject drugs (PWID) during acute HCV infection with different outcomes. RESULTS: Early acute HCV was associated with high variability in type III IFNs plasma levels and the favorable IFN-λ3 CC genotype was associated with higher viral loads. Reduced expression of Natural Killer Group Protein 2A (NKG2A) was associated with lower IFN-λ3 plasma levels and the CC genotype. IFN-γ production by NK cells was higher in individuals with the CC genotype during acute infection but this did not prevent viral persistence. IFN-λ3 plasma levels did not correlate with function of NK cells and IFN-λ3 prestimulation did not affect NK cell activation and function. CONCLUSIONS: These results suggest that IFN-λ3 polymorphism indirectly influences NK cell phenotype and function during acute HCV but other factors may act in concert to determine the outcome of the infection.

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
