Random linker-insertion mutagenesis to identify functional domains of herpes simplex virus type 1 glycoprotein B.

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

Insertion mutations in herpes simplex virus 1 glycoprotein H reduce cell surface expression, slow the rate of cell fusion, or abrogate functions in cell fusion and viral entry.

Of the four required herpes simplex virus (HSV) entry glycoproteins, the precise role of gH-gL in fusion remains the most elusive. The heterodimer gH-gL has been proposed to mediate hemifusion after the interaction of another required glycoprotein, gD, with a receptor. To identify functional domains of HSV-1 gH, we generated 22 randomized linker-insertion mutants. Analyses of 22 gH mutants reve...

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...

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 ...

Polymeric display of immunogenic epitopes from herpes simplex virus and transmissible gastroenteritis virus surface proteins on an enteroadherent fimbria.

The strong immunogenicity of bacterial fimbriae results from their polymeric and proteinaceous nature, and the protective role of these immunogens in experimental or commercial vaccines is associated with their capacity to induce antiadhesive antibodies. Fimbria-mediated intestinal colonization by enteropathogens typically leads to similar antibody responses. The possibility of taking advantage...
