Human T cell leukemia/lymphoma virus type-1 (HTLV-1) is recognized as the etiological agent of adult T cell leukemia (ATL). Although HTLV-1 can immortalize human lymphocytes in culture, identification of molecular events leading to tumorigenesis after HTLV-1 infection remain elusive. SCID/bg and NOD/SCID mice have reduced natural killer (NK) cell activity and were inoculated intraperitoneally with HTLV-1 transformed cells to refine and characterize the SCID mouse as a small animal model for investigation of HTLV-1 tumorigenesis. HTLV-1 transformed cell lines originally derived by cocultivation of uninfected peripheral blood mononuclear cells (PBMC) with lethally irradiated leukemic cells from patient samples (SLB-1, MT-2 and HT-1-RV) were lymphomagenic when inoculated into NOD/SCID mice. In contrast, immortalized cell lines generated by transfection PBMC with an infectious molecular clone of HTLV-1 (ACH or ACH.p12) were not tumorigenic. The differing behaviors of HTLV-1 infected cell lines in NOD/SCID mice indicates that viral infection and immortalization of human PBMC for growth in culture is not sufficient for induction of a tumorigenic phenotype. The higher level of engraftment of HTLV-1 transformed cell lines in NOD/SCID mice suggests that this is an effective animal model to investigate molecular determinants of HTLV-1 lymphomagenesis.
