By contrast, at 7 days post infection, the levels of CCL2, CCL3, CXCL2, IFN-γ and the anti-inflammatory cytokine IL-10 were significantly lower in influenza A virus-infected Nox1−/y lung compared to WT control, whereas IL-β, IL-6, TNF-α, and GM-CSF were similar between the two strains of mice (Figure 2). Here, CCL3 is linked to infection.
