FIG. 4.

Enhanced macrophage activation in livers of infected memTNF mice. WT (black bars) and memTNF (gray bars) mice were infected with 2,000 CFU of Listeria intravenously. mRNA expression in the livers from uninfected mice and infected mice was measured by RTQ-PCR to determine the relative (rel.) expression of LRG-47 and iNOS. The data are the means and standard errors for five mice per group from one of two representative experiments. Significance was determined by ANOVA. An asterisk indicates that the P value was <0.05 for a comparison of memTNF and WT mice.
