Phenotypic and functional consequences of herpesvirus saimiri infection of human CD8+ cytotoxic T lymphocytes

Abstract

Herpesvirus saimiri (HVS) was used to infect and transform human CD8+ cytotoxic T lymphocytes (CTL), and the phenotypic and functional consequences of HVS infection of CD8+ T lymphocytes were investigated. HVS-transformed CTL no longer require antigen restimulation yet maintain their phenotype and HLA-restricted cytolytic function and specificity. The ability of HVS to transform CTL may have an important role in the functional analysis of human antigen-specific CTL.
