CT hybridomas: tumor cells capable of lysing virally infected target cells

CT hybridomas: tumor cells capable of lysing virally infected target cells

Journal of Immunology 129(2): 900-903

By fusing primed murine lymphocytes with a syngeneic T cell lymphoma, we have been able to select for H-2-restricted, virus-specific cytotoxic T cell hybridomas (CTH). These T cell hybrids, which replicate in ordinary tissue culture medium or in ascites, are capable of lysing virally infected target cells, and their activity is facilitated by the presence of lectins in the assay medium. Unlike cells mediating lectin nonspecific lysis, these hybridomas are H-2 restricted and specific for single viral proteins. The ability to maintain these cells in culture for over 18 mo and to pass them in vivo without loss of activity or specificity indicates that they will provide sufficient material for the analysis of surface proteins and genetic information required for the recognition and lysis of virally infected cells by killer T cells.
