Figure 4. M45mutRHIM virus attenuation in vivo is reversed in DAI−/− mice.
(A) Footpad swelling induced by parental WT or M45mutRHIM MCMV infection. Footpad thickness of C57BL/6 control (top) and DAI−/− (bottom) mice inoculated with 106 pfu was measured with a digital caliper, and mean values plotted at the indicated times over a 14 day time course (n=7–9 animals/group). (B–D) Viral titers from spleen (B), liver (C), and SGs (D) of control (C57BL/6), RIP3−/−, and DAI−/− mice infected via intraperitoneal inoculation with 106 pfu of indicated virus and harvested at the indicated time (n= 5–10 animals/group). Error bars, SEM. See also related Figure S4.
