PG - 145-59 AB - Immunization studies with HSV-1 and HSV-2 envelope proteins expressed in Escherichia coli were performed. After active immunization of mice with a gD-1 antigen (Leu53-Ala312) expressed as a fusion protein, the animals were protected from a lethal challenge with HSV-1 and HSV-2. In addition, antisera from rabbits immunized with the same gD-1 antigen also conferred passive immunity to mice against a challenge infection with either HSV-1 or HSV-2. In contrast to these successful gD-1 protection experiments, various gC-1 and gC-2 fusion proteins from E. coli failed to induce protective immunity. Moreover, the mice sera from immunized animals were not able to react with the authentic, glycosylated gC-1 and gC-2 envelope proteins, whereas sera raised against authentic gC-1 and gC-2 glycoproteins do recognize the gC fusion proteins from E. coli. These results indicate, that E. coli might represent an ideal system for expressing gD antigens as a possible component of a HSV vaccine, whereas gC antigen cannot be produced in an immunocompetent form in E. coli.
