Glycoprotein D protects mice against lethal challenge with herpes simplex virus types 1 and 2.

摘要

Glycoprotein D is a virion envelope component of herpes simplex virus types 1 and 2. Sets of mice were immunized with purified gD-1 or gD-2 and were challenged with a lethal dose of herpes simple virus, either type 1 or type 2. All or virtually all of the immunized mice survived challenge with either agent, whereas challenge of sham-immunized mice was almost always fatal. Serum samples taken before challenge contained gD-specific antibodies which had 50% neutralization titers ranging from 1:16 to 1:512 against homologous and heterologous virus types. We conclude that either gD-1 or gD-2 is a potential candidate for a subunit vaccine against herpetic infections.
