Relative mRNA expression of CXCL9, CXCL10, CXCL13, CXCL16, CCL2, and CCL5 3 weeks after infection in the livers of WT (A) and WT versus IFN-γ−/− (B) mice. RT-PCR results (mean ± SEM) are from 2 experiments (A) (8 mice per group) and from 1 experiment (B) (4 mice per group). In panel A, P was <0.05 for all results for expression in the livers of infected WT mice versus expression in the livers of 8 naive (uninfected) WT mice, and the + symbols for uninfected mice for CXCL13 and CCL2 indicate values of 3.6 ± 1.6 and 0.33 ± 0.9 units, respectively. In panel B, P was <0.05 for all results for infected WT mice versus infected IFN-γ−/− mice, and the + symbols for IFN-γ−/− mice indicate values for CXCL13 and CCL2 of 1.5 ± 0.6 and 1.3 ± 0.3 units, respectively.
