FIG 5.

Immunization with EHV-1 KyA increases the number of genes with changed expression in the lungs of CBA mice upon RacL11 challenge. The numbers of genes from the total microarray data sets that showed a >2.0-fold increase (red) or a >2.0-fold reduction (blue) in expression (P ≤ 0.05) are given. Data for KyA and RacL11 were obtained at 8 h postinfection. Data for KyA- or heat-inactivated KyA-immunized mice challenged with RacL11 (KyA → RacL11 or HI-KyA → RacL11, respectively) were obtained at 8 h post-RacL11 challenge.
