Previous transgenic work demonstrated transforming activity of the human T-cell leukemia virus type I Tax protein in fibroblasts. In the present study, a Thy-1-based vector was used to express Tax in thymocytes. These mice developed no functional or neoplastic abnormalities of T cells but developed fibroblastic tumors with a longer latency than in the previous model.
