Figure 8.
Influence of IDEs on the course of infection in HCT recipients. Following regimen “B” of Figure 6, virus replication in HCT recipients infected with mCMV-Δ4IDE, lacking IDEs (open circles), or mCMV-Δ4IDE-rev, expressing IDEs (filled circles), was quantitated over a period of 20 weeks in the spleen (top), lungs (center), and liver (bottom) during hematopoietic reconstitution. Symbols represent data from individual mice, dashes represent the median values. Virus titers in spleen and lungs refer to the whole organ, the numbers of IHC-detected, infected (IE1+) liver cells (mostly hepatocytes) refer to representative 10-mm2 areas of liver tissue sections. P-values compare data for mutant virus (open circles) and revertant virus (filled circles) cumulated for the time points that precede the reconstitution of CD8+ T cells.
