Abstract
Immune responses in vitro of some species of marmosets to herpesvirus-associated antigens expressed on virus-transformed lymphoblastoid cell lines (LCL) were studied by determining lymphocyte proliferation, interferon production, and the induction of cytotoxic effector cells in mixed lymphocyte-LCL cultures (MLLC). Autologous Epstein-Barr virus (EBV)-transformed B-cell lines induced neither lymphocyte proliferation nor interferon production in MLLC, while autologous Herpesvirus ateles (HVA)-transformed T-cell lines stimulated responder cell DNA synthesis and interferon production. Both EBV-LCL and HVA-LCL failed to induce cytotoxic effector cells in autologous MLLC responder cells. These findings differ markedly from the human immune response to autologous EBV-LCL in vitro and may have implications for the unusual susceptibility of marmosets to the induction of lymphoproliferative disease following inoculation with oncogenic herpesviruses.
