The serological response to the ICP-35 group of herpes simplex virus type 2 (HSV-2) proteins was examined 30 d after vaginal challenge with HSV-2 of guinea pigs previously immunized with HSV glycoproteins. Detection of antibodies to ICP-35 proteins correlated best with the magnitude of vaginal viral replication. Animals that developed antibody to ICP-35 proteins had more-frequent recurrences (P less than .0002) that were of longer duration (P less than .005) than animals that did not. By covariate analysis the number of recurrences appeared to be related to the severity of the acute disease, inversely related to the enzyme-linked immunosorbent assay titer of antibody to HSV glycoproteins, and related to the detection of antibody to ICP-35 proteins. The duration of recurrent disease, however, could only be correlated with the presence of antibody to ICP-35 proteins. Detection of antibody to ICP-35 proteins is thus a useful prognostic indicator for identifying animals that developed more-severe recurrent disease.

The members of this family were identified and studied with the aid of a panel of monoclonal antibodies exemplified by H745. This monoclonal antibody reacted with six bands (ICP35a to 35f) formed by ICPs contained in either HEp-2 or Vero cell lysates electrophoretically separated in denaturing gels and transferred to nitrocellulose sheets.

Infected cell proteins (ICPs) synthesized in the presence of the nucleoside analogues were compared by sodium dodecyl sulphate (SDS) polyacrylamide gel electrophoresis to ICPs from non-drug-treated cells and it was found that there was no effect on HSV-1-induced alpha proteins but beta and gamma proteins were reduced as much as 60%. There were three exceptions: ICP 35 (Mr = 46,000) and ICP 39 (Mr = 36,000) were not reduced and ICP 36 (Mr = 42,000) was increased during drug treatment.
