title: Protection from retinal necrosis by passive transfer of monoclonal antibody specific for herpes simplex virus glycoprotein D.
abstract: Passive administration of antibody against herpes simplex virus type 1 (HSV-1) has been shown to protect against stromal keratitis and death from encephalitis. Although the exact mechanism by which passively-transferred antibody protects is not known, one of the features of protection by passively-transferred antibody is interference with the ability of the virus to spread within the nervous system. In the experiments reported herein, studies were performed to determine if 8D2, a monoclonal antibody against a type-common epitope of glycoprotein D, could protect mice from retinal necrosis following uniocular anterior chamber inoculation of HSV-1. Mice were protected from retinal necrosis when the antibody was administered 2 hours before virus inoculation or 24 hours after virus inoculation. When antibody was injected 2 hours before virus inoculation, the titer of virus at day 1 p.i. in the injected eyes of antibody-treated and control mice was the same, but by 3 days p.i., the titer of virus in the antibody-treated mice was significantly lower than that recovered from control mice. The titers of virus in the brains and in the uninoculated eyes of antibody-treated mice were also significantly lower than in control mice. The results of these studies suggest that passively-transferred antibody protects against retinal necrosis by limiting spread of virus to the CNS or replication of virus within the CNS.
