Abstract: | A protein related to glycoprotein B of herpes simplex virus type 1 (HSV-1) produced in yeast (ygB-1) was purified with an immunoadsorbent. The molecular weight of the purified ygB-1 as determined by sodium dodecyl sulphate polyacrylamide gel electrophoresis was 96,000. Mice injected twice with ygB-1 adsorbed to alum developed ELISA antibody to ygB-1, neutralizing antibody to HSV-1 and a lymphoproliferative response to ygB-1 and HSV-1. The immunized mice were protected against intraperitoneal and corneal challenge with HSV-1. Latent infection in the trigeminal ganglia after corneal challenge was also inhibited by immunization with ygB-1. Guinea-pigs pigs immunized with ygB-1 adsorbed to alum also developed ELISA antibody to to ygB-1 and neutralizing antibody to both types of HSV. After the second dose, strong lymphoproliferative responses were seen upon stimulation with HSV-2. Animals were protected against intravaginal challenge with HSV type 2. |
