Soluble glycoprotein D blocks herpes simplex virus type 1 infection of rat eyes.

ABSTRACT

Herpes simplex virus type 1 (HSV-1) ocular infection in rats was blocked by treating the eyes with UV-inactivated virions containing glycoprotein D (gD) prior to ocular challenge. In contrast, rats treated with UV-inactivated virions lacking gD were not protected. A soluble, truncated form of HSV-2 gD (gD-2t) also protected against ocular infection. Treatment with gD-2t not only reduced mortality but also restricted progression of pathology and reduced the amount of viral antigen in the cornea. Host antibody or alpha/beta interferon responses to the gD-2t treatment were not detected. These results are similar to those observed in cell culture (D. C. Johnson, R. L. Burke, and T. Gregory, J. Virol. 64:2569-2576, 1990). The in vivo effect of exogenous gD is consistent with blocking of a cell surface gD receptor or with an inhibitory interaction of gD with virions.
