Attachment but Not Penetration of Bovine Herpesvirus 1 Is Necessary To Induce Apoptosis in Target Cells

Abstract

Bovine herpesvirus 1 (BHV-1) induces apoptotic cell death in bovine peripheral blood mononuclear cells and B-lymphoma cells. Using a BHV-1 glycoprotein H null mutant, we have demonstrated that although penetration of BHV-1 is not required, attachment of BHV-1 viral particles is essential for the induction of apoptosis.
