Thymidine kinase negative (TK−) mutants of HSV-1 were used to attempt to rescue HSV-2 genes from cells biochemically transformed with HSV-2 DNA. The results indicate that the occurrence of a rescue event was less than 7 × 10−7 in this system.

Human cells in culture (HEp-2) were infected with herpes simplex virus type 2 (HSV-2) at multiplicities of infection varying from 0.2 to 10, and fixed 6, 12, 18 and 24 hr after infection. Infection-related antigens were detected by an indirect double antibody (peroxidase conjugated goat anti-rabbit to rabbit anti-herpes simplex virus type 2) immunoenzymatic staining reaction that rendered infection-related antigens visible by light microscopy. A corresponding series of laser flow cytophotometric experiments yielded reproducible large-angle (1-19 degrees) laser-light scattering distributions that depended upon multiplicities of infection and the location of the infection-related antigens in the infected cells.

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.
