In addition, inactivation of influenza by UV did not abolish the influenza viruses-stimulated CXCL10 secretion by AM (Figures 3 and 4), which is different from studies with human monocyte-derived macrophages [21], [51] and with human alveolar type II epithelial cells isolated from the same donors ([34] and data not shown). This evidence concerns the gene CXCL10 and influenza.
