Intriguingly, a positive correlation between type 1 inflammatory mediators (e.g., IFNγ and CXCL10) and eosinophil activation was observed, suggesting that, particularly in moderately affected patients, part of the granulocyte compartment could be actively participating in the efficient viral clearance, similarly to what can occur upon influenza infection. This evidence concerns the gene CXCL10 and influenza.
