New mouse model of acute adult T-cell leukemia generated by transplantation of AKT, BCLxL, and HBZ-transduced T cells.

ABSTRACT: Adult T-cell leukemia/lymphoma (ATL) develops in human T-cell leukemia virus type 1 (HTLV-1) carriers. Although the HTLV-1-encoded HBZ gene is critically involved, HBZ alone is insufficient and additional, cooperative "hits" are required for the development of ATL. Candidate cooperative hits are being defined, but methods to rapidly explore their roles in ATL development in collaboration with HBZ are lacking. Here, we present a new mouse model of acute type ATL that can be generated rapidly by transplanting in vitro-induced T cells that have been retrovirally transduced with HBZ and two cooperative genes, BCLxL and AKT, into mice. Co-transduction of HBZ and BCLxL/AKT allowed these T cells to grow in vitro in the absence of cytokines (Flt3-ligand and interleukin-7), which did not occur with
