Human cytotoxic T cell clones directed at autologous virus-transformed targets: further evidence for linkage of genetic restriction to T4 and T8 surface glycoproteins.

Type: article
Abstract: Human cytotoxic T cell clones were generated against autologous EBV-transformed B lymphocytes. Whereas the majority of the clones expressed the T8 surface glycoproteins and showed a specificity for class I MHC gene products on the target cell, a minority expressed the T4 surface glycoprotein and demonstrated a class II specificity. Monoclonal antibodies to T4 and T8 inhibited cytotoxic effector function of reactive clones in a fashion analogous to their effect on alloreactive CTL clones. Each autoreactive T cell clone was cytotoxic for EBV-transformed B lymphocytes but not pokeweed mitogen-activated or resting autologous lymphocytes, suggesting a dual specificity for an MHC gene product as well as an antigen induced and/or encoded by virus. Taken together, the present findings provide further support for the notion that T4 and T8 serve as associative recognition elements on T lymphocytes for MHC gene products.
