Humoral immune response to herpes simplex virus type 2 glycoproteins in patients receiving a glycoprotein subunit vaccine.

Abstract：

:Serial serum specimens from 22 herpes simplex virus (HSV)-seronegative recipients of an HSV type 2 (HSV-2) glycoprotein subunit vaccine were analyzed by radioimmunoprecipitation and polyacrylamide gel electrophoresis for the development of antibodies to HSV-2 gB, gD, and g80, a complex of gC and gE. Volunteers received 50 (n = 12) or 100 micrograms (n = 10) of vaccine at days 0, 28, and 140; sera were drawn weekly for 8 weeks and again at days 140, 147, and 365. Among seronegative volunteers, antibody to gB was detected 2 weeks after the first dose, while antibodies to g80 and gD were detected after the second dose (day 35). Antibodies to nonglycosylated HSV-specific proteins were not detected. A dose-response effect between recipients of 50- and 100-micrograms doses was observed in the proportion of vaccine recipients seroconverting to g80 and in the proportion of recipients retaining antibodies to both gD and g80 over time. Diminishing complement-independent neutralizing antibody titers occurred after the second dose and were associated with loss or reduction of detectable antibody to gD. Volunteers who were seropositive for HSV-1-specific antibody (n = 11) were also enrolled in the trial and received 50-micrograms doses of vaccine. Vaccination resulted in conversion to HSV-2 complement-independent neutralizing antibody specificity or indeterminant specificity in 10 of 11 volunteers. These shifts were accompanied by changes in the radioimmunoprecipitation and polyacrylamide gel electrophoresis profile. These changes, which were apparent by 14 days after the first vaccine dose, included de novo appearance or increased levels of antibody to g80 and increased levels of antibody to gD and gB. These studies document the immunogenicity of solubilized glycoproteins gB, gD, gC, and, possibly, gE in humans.
