Immune response to herpes simplex virus infections: virus-specific antibodies in sera from patients with recurrent facial infections.

AUTOR(ES)
RESUMO

Radioimmunoprecipitation assays were used to identify antibodies against a number of herpes simplex virus type 1-specific antigens in serum samples from individuals with recurrent facial herpes virus infections and from seropositive individuals without recurrent infections. Individuals with recurrent infections contributed three sequential serum samples each: immediately after the appearance of lesions, 3 weeks later, and 3 months later. Antibodies against at least 18 viral polypeptides were present in all positive sera: these included antibodies against the major nucleocapsid polypeptide (approximate molecular weight, 150,000) and against two glycopolypeptides with molecular weights of 115,000 to 130,000. No significant differences were observed between the serum samples in regard to their virus-specific antibody composition. The high-molecular-weight glycopolypeptides were partially purified and used in quantitative titration experiments. All sera tested were equally reactive with this material. It was concluded that under the experimental conditions an individual's susceptibility to recurrent herpetic infections could not be correlated with quantitative or qualitative changes in the levels of virus-specific antibodies.
