FIG. 4.
ΔM36 growth is not rescued in TNFRp55−/− mice. TNFRp55−/− mice and mice of their parental strain C57BL/6 were i.v. infected with 106 PFU of either ΔM36 (○) or WT-MCMV (•). Virus in lung homogenates was quantified on days 3 by virus plaque assay. Circles represent individual mice. Differences between median values are highlighted by shading. DL, detection limit of the assay.
