Passive Immunization of Mice with Monoclonal Antibodies to Glycoprotein gB of Herpes Simplex Virus

Abstract
To investigate the protective ability of monoclonal antibodies (MCA) to viral glycoprotein in herpes simplex virus (HSV) infection, athymic nude mice were inoculated intracutaneously with HSV type-1 (HSV-1) in the midflank. Three hours after inoculation, 1 group of mice was passively immunized with 1 of a series of MCA to glycoprotein gB of HSV-1, and a control group of mice was given phosphate buffered saline alone. The control mice died within 16 days after infection; the mice passively immunized with any of the MCA showed suppressed development of skin lesions. Three of 6 mice given MCA failed to develop any visible lesions and no HSV could be isolated from the lumbar dorsal root ganglia of these mice 60 days after the challenge. BALB/c mice were also protected from infection with HSV type 2 by passive immunization with MCA to HSV-1 gB.
