Sex-matched 8–12-wk-old mice of the indicated genotype (129Sv/Ev background, H-2b) were infected i.v. with LCMV-WE (2 × 106 PFU per mouse; four mice per group). Blood was collected from the retrobulbar plexus of individual mice at the indicated timepoints. Cellular blood values were quantified in hemocytometer and differential blood counts were determined microscopically from blood smears.
RBC, total erythrocytes (×109/ml); WBC, total leucocytes (×106/ml); reticulocytes, platelets, neutrophils, eosinophils, lymphocytes, and monocytes (×106/ml).
Data represent means ± SD. Student's t-tests for differences between LCMV-WE–infected IFN-α/β R0/0 vs IFN-γ R0/0 mice on day 3 after infection:
P <0.0001;
P <0.0001;
P <0.01.
