In Vivo Role of Complement-Interacting Domains of Herpes Simplex Virus Type 1 Glycoprotein Gc

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

Blocking immune evasion as a novel approach for prevention and treatment of herpes simplex virus infection.

Many microorganisms encode immune evasion molecules to escape host defenses. Herpes simplex virus type 1 glycoprotein gC is an immunoevasin that inhibits complement activation by binding complement C3b. gC is expressed on the virus envelope and infected cell surface, which makes gC potentially accessible to blocking antibodies. Mice passively immunized with gC monoclonal antibodies prior to inf...

Herpes simplex virus type 1 glycoprotein gC mediates immune evasion in vivo.

Many microorganisms encode proteins that interact with molecules involved in host immunity; however, few of these molecules have been proven to promote immune evasion in vivo. Herpes simplex virus type 1 (HSV-1) glycoprotein C (gC) binds complement component C3 and inhibits complement-mediated virus neutralization and lysis of infected cells in vitro. To investigate the importance of the intera...

Herpes simplex virus type 1 evades the effects of antibody and complement in vivo.

Herpes simplex virus type 1 (HSV-1) encodes a complement-interacting glycoprotein, gC, and an immunoglobulin G (IgG) Fc binding glycoprotein, gE, that mediate immune evasion by affecting multiple aspects of innate and acquired immunity, including interfering with complement components C1q, C3, C5, and properdin and blocking antibody-dependent cellular cytotoxicity. Previous studies evaluated th...

Implications for herpes simplex virus vaccine strategies based on antibodies produced to herpes simplex virus type 1 glycoprotein gC immune evasion domains.

Herpes simplex virus type I (HSV-1) glycoprotein gC (gC-1) is an immune evasion molecule that inhibits complement activation by binding C3b. Three assays were used to assess whether IgG antibodies produced by HSV-1 infection in humans block the interaction between C3b and gC-1. In two assays human IgG had no effect, while in one assay IgG partially inhibited C3b binding, which occurred at IgG c...
