title: Immune evasion by gamma-herpesviruses.
abstract: Persistent viruses, such as herpesviruses, transmit infection by evading cytotoxic T cells during lytic replication. The gamma-herpesviruses additionally evade T cells during the proliferation of latently infected lymphocytes to establish a persistent viral reservoir. Lytic gene expression in sites of lymphoproliferation appears to make a vital contribution to this latent immune evasion. Lytic antigens may therefore be a key immune target. Investigations into a murine gamma-herpesvirus have now provided evidence that vaccination with apathogenic, latency-deficient mutants can largely protect against subsequent wild-type gamma-herpesvirus latency establishment.
