Enhanced pathogenesis of an attenuated herpes simplex virus for mice lacking Stat1.
Mice lacking the Stat1 interferon signaling gene were infected with herpes simplex virus type 1 (HSV-1) or an attenuated recombinant lacking virion host shutoff (Delta vhs). Delta vhs virus-infected Stat1(-/-) mice showed levels of replication equivalent to that of the wild-type virus-infected control mice but reduced relative to wild-type virus-infected Stat1(-/-) mice. Stat1 deficiency relieves the immunomodulatory deficiency of Delta vhs virus, but not its inherent growth defect. Also Vhs is dispensable for reactivation.
