Insertion mutants of herpes simplex virus have a duplication of the glycoprotein D gene and express two different forms of glycoprotein D.

Expression of the Herpes Simplex Virus Type 2 Glycoprotein D in Baculovirus Expression System and Evaluation of Its Immunogenicity in Guinea Pigs

Background: Herpes simplex virus type 2 (HSV-2) is highly prevalent and major cause of genital herpes in humans. The life-long nature of infection and the increasing prevalence of genital herpes imply that vaccination is the best strategy for controlling the spread of infection and limiting HSV disease. HSV glycoprotein D (gD) is one of the most important viral immunogen which has an essential ...

Construction of an Eukaryotic Expression Vector Encoding Herpes Simplex Virus Type 2 Glycoprotein D and In Vitro Expression of the Desired Protein

To construct of an eukaryotic expression vector encoding herpes simplex virus type 2 (HSV-2) glycoprotein D (gD2), an Iranian isolate of HSV-2 was propagated in HeLa cell line and its DNA was extracted and used as template in polymerase chain reactions (PCR), to amplify gD2 gene. Primers were designed and the restriction enzyme sites for EcoRI and XhoI were considered at their 5′ ends respectiv...

Immunogenicity and Efficacy of Baculovirus Derived Glycoprotein D of Herpes Simplex Virus Type-I in Mice

Detection of Herpes Simplex Virus Antibodies Using the Whole Virus and Recombinant gD

Background and Aims: Herpes simplex virus type 1 (HSV1) remains a potentially serious health problem world wide. All infected people, including asymptomatic ones, are potential sources for virus transmission. Virus envelope contains at least 13 glycoproteins, which glycoprotein D is the major target of immune responses. The aim of this study was development of a specific method that is a more...

Replication Characteristics of Herpes Simplex Virus Type-1 (HSV-1) Recombinants in 3 Types of Tissue Cultures

A complication in the analysis of the role of ICP34.5 gene in the herpes simplex virus type-1 (HSV-1) lifecycle is the presence of overlapping antisense gene, open reading frame P (ORF P), which is also deleted in HSV-1 ICP34.5 negative mutants. A HSV-1 wild type strain (17+) ICP34.5/ORF P deletion mutant (1716) is totally avirulent in animal models and impaired in a number of in vitro function...
