T-cell recognition of the secreted and membrane-bound portions of the herpes simplex virus type 2 (HSV-2) glycoprotein G (sgG-2 and mgG-2, respectively) was compared in symptomatic and asymptomatic HSV-2-infected individuals and in HSV-2-seronegative controls and the responses with HSV-1 glycoproteins C and E (gC-1 and gE-1) were compared. CD4+ T cells from HSV-2-infected individuals specifically recognized both sgG-2 and mgG-2, whereas HSV-1-infected and HSV-seronegative controls did not respond to these glycoproteins. The responses to gC-1 and gE-1, on the other hand, were not type specific, as blood mononuclear cells from both HSV-1- and HSV-2-infected individuals responded in vitro. There was an association between the status of the infection (symptomatic versus asymptomatic) and the CD4+ T-cell responsiveness. Symptomatic HSV-2-seropositive individuals responded with significantly lower Th1 cytokine production to sgG-2 and mgG-2 than did asymptomatic HSV-2-infected carriers, especially within the HSV-1-negative cohort. No differences in T-cell proliferation were observed between asymptomatic and symptomatic individuals. The results have implications for studies of HSV-2-specific CD4+ T-cell reactivity in general and for analysis of immunological differences between asymptomatic and symptomatic individuals in particular.

The contribution of virus components to liberation of herpes simplex virus type 2 (HSV-2) progeny virions from the surface of infected cells is poorly understood. We report that the HSV-2 mutant deficient in the expression of a mucin-like membrane-associated glycoprotein G (mgG) exhibited defect in the release of progeny virions from infected cells manifested by ~2 orders of magnitude decreased amount of infectious virus in a culture medium as compared to native HSV-2. Electron microscopy revealed that the mgG deficient virions were produced in infected cells and present at the cell surface. These virions could be forcibly liberated to a nearly native HSV-2 level by the treatment of cells with glycosaminoglycan (GAG)-mimicking oligosaccharides. Comparative assessment of the interaction of mutant and native virions with surface-immobilized chondroitin sulfate GAG chains revealed that while the mutant virions associated with GAGs ~fourfold more extensively, the lateral mobility of bound virions was much poorer than that of native virions. These data indicate that the mgG of HSV-2 balances the virus interaction with GAG chains, a feature critical to prevent trapping of the progeny virions at the surface of infected cells.
