Infection with the UL88-Rev-mCh virus did not alter NF-κB p65 staining in infected cells and restored nuclear NF-κB staining in uninfected cells to the WT levels, indicating that this effect is specific to UL88 and not to any potential point mutants generated during the construction of the UL88-STOP-mCh virus. This evidence concerns the gene NFKB1 and infection.
