Evaluation of lung cytokines. qRT-pCR for mRNA relative expression of IL12p40, IFNγ, TNFα, Fpr2, CXCL10, and Fpr2 by mouse right lungs homogenized on day 7, 24 h after receiving either no treatment or 2 treatments of soluble CpG or PRINT-CpG. Data are normalized to Gapdh mRNA and graphed as fold change over non-tumor-bearing lungs. Statistics performed by 1-way ANOVA with Tukey’s multiple comparisons test, *p < 0.05, **p < 0.001, ***p < 0.0005.
