Seven monoclonal antibodies (mAb) specific for defined discontinuous and continuous epitopes on glycoprotein D of herpes simplex virus type 1 (HSV-1) were surveyed for their capacity to protect against virus-induced corneal disease in a murine ocular infection model. A known amount of purified mAb was transferred passively to BALB/c mice 24 hr after topical infection with HSV-1 on their scarified corneas. At high doses (50-136 micrograms), all seven mAbs protected against the development of persistent necrotizing stromal keratitis. Significant protection was also observed at low doses (20 micrograms) with two mAbs to discontinuous epitopes and two mAbs to continuous epitopes. Selected high-dose mAbs also were able to reduce the severity of blepharitis. These results indicated that at least seven different antigenic sites on glycoprotein D can serve as targets for effective antibody therapy in the murine model of HSV-1 ocular infection.
