Cytokine levels in lungs of SLPI KO and WT^KO mice. The bars represent the mean ± SEM (n = 6 per group). *p < 0.001, for IL-4, IL-5, IL-6, IL-2, and MCP-1 in KO-PBS mice versus KO-OVA mice and for WT^KO-PBS mice versus WT^KO-OVA; **p < 0.05, for IFN-γ, RANTES, and TNF-γ in KO-PBS mice versus KO-OVA mice and WT^KO-PBS mice versus WT^KO-OVA mice.
