title: B7 costimulation plays an important role in protection from herpes simplex virus type 2-mediated pathology.
abstract: We have used mice lacking both B7-1 and B7-2 costimulation molecules (B7KO) to investigate the effects of B7 costimulation on herpes simplex virus type 2 (HSV-2) pathogenesis. B7KO mice infected intravaginally with virulent HSV-2 showed more severe genital and neurologic disease and higher mortality rates than their wild-type counterparts. These results suggest that B7 costimulation molecules play an important role in the development of primary immune responses protective against HSV-2.
