Figure 6. Increased viral load in mice lacking GzmB.

The indicated mouse strains were infected with 2×10⁴ pfu of MCMV Δm157. At days 4 and 6 post-infection viral loads in the (A) spleen, (B) liver and (C) lungs were quantified by plaque assay. Data are pooled from 3 independent experiments, mean ± SEM are plotted, where n≥6. *P<0.05.**P<0.005.
