Cytokine and chemokine gene expression in spleens and lungs of MAPV-infected deer mice. Fourteen days post infection, spleens and lungs of 5 deer mice were examined for the expression of 10 genes by real-time PCR. Ccl2, Ccl3 and Tgfb were elevated in spleens of infected deer mice (dark gray) compared to uninfected deer mice (light gray), whereas Il23 expression was repressed. Error bars represent 95% confidence intervals and those denoted by * are statistically different from the uninfected control. Heat map indicates fold-change of individual deer mice used in generating the graph of infected deer mice (DM17–DM22) and uninfected controls (DM.C1, DM.C2) (a). In lungs, only Ccl3 and Cxcl2 were elevated.
