Abstract

We have successfully isolated continuous T cell lines from murine spleen which have been induced to proliferate after in vitro exposure to the murine leukemia virus RadLV. Cell lines isolated from several strains of mice have an "immature" phenotype and are immortalized CD4- CD8- CD3+ cell lines. Cell lines of similar phenotype have now been derived from many individual mice, after spleens have been infected with two different RadLV viruses, a leukemogenic and a nonleukemogenic isolate. Among cell lines induced with RadLV/C6VL, an unusually high proportion of cells was found to bind the 124-40 anticlonotypic antibody specific for the alpha beta TCR expressed by C6VL/1 cells which produces RadLV/C6VL. This was not reflected in cell lines induced with the RadLV/V13 isolate nor in various lymphocyte subsets freshly isolated from normal mice, or induced to proliferate in culture. Cells expressing a common TCR structure would appear to be appropriate targets for in vitro proliferation and transformation induced by RadLV.
