IgG subclass of anti-HSV antibodies following neonatal HSV infections

摘要

Ten survivors of neonatal HSV encephalitis had IgG1 and IgG3 antibodies to HSV 6 or more months after their infection. Six had IgG4 antibodies but only one had IgG2 antibodies. Titers of anti-HSV antibodies were similar following neonatal and later HSV infections. Antibody deficiency is thus not part of the selective deficiency of HSV-specific immunity following neonatal infection.
