Regulation of expression of herpes simplex virus (HSV) glycoprotein D in vaccinia recombinants affects their ability to protect from cutaneous HSV-2 disease

J Infect Dis. 1989 Apr;159(4):625-34. doi: 10.1093/infdis/159.4.625.

Abstract

The effect of regulation of herpes simplex virus (HSV) type 1 glycoprotein D (gD-1) gene expression on HSV-specific immune response and protection from cutaneous HSV-2 disease was studied using vaccinia virus recombinants containing gD-1 under the control of early (VP176) or late (VP254) vaccinia virus promoters. Expression of gD-1 in VP176-infected cells was first observed at 2 h after infection. It did not depend on viral DNA replication. In VP254-infected cells, gD-1 was first observed at 24 h after infection and its expression depended on DNA replication. Immunized guinea pigs had similar titers of HSV-specific neutralizing antibody. However, HSV-specific T cell responses were significantly higher in VP176- than in VP254-immunized animals as determined by lymphoproliferation (P less than .005) and delayed type hypersensitivity (P less than .01). The reduced T cell responses of VP254-immunized guinea pigs correlated with poor gD-1 expression in VP254-infected antigen presenting cells (splenic adherent and epidermal cells). Immunization with VP176, but not with VP254, protected guinea pigs from primary (P less than .0005) and recurrent (P less than .0005) cutaneous HSV-2 lesions.
