Research summary

Myeloid leukemia occurs in two forms, the rapidly progressing acute myeloid leukemia (AML) and chronic myeloid leukemia (CML), in which leukemic cells expand slowly in bone-marrow and other blood-forming organs. AML and CML cells are frequently sensitive to the anti-leukemic functions of natural killer (NK) cells and T cells, and therapies aiming to boost the function of these cells may be useful in eradicating the leukemic clone.

A major aim of our research is to define, utilizing a translational approach, the role of cytotoxic lymphocytes in AML and CML with focus on mechanisms of immunosuppression (oxygen radical production by leukemic cells, myeloid-derived suppressor cells) that may stifle the immune-mediated clearance of leukemic cells. The studies are, in part, based on our finding of a novel mechanism of immunosuppression in leukemia, in which myeloid leukemic cells produce reactive oxygen species (ROS) that kill adjacent NK cells and T cells by inducing apoptosis (Aurelius et al., Blood, 2012; Aurelius et al., J Leukocyte Biol, 2013).

A parallel and related aim is to define mechanisms of differentiation of myeloid leukemic cells to form the basis for treatments that promote the maturation of leukemic cells into functional leukocytes.

A close collaboration with clinical units allow the recovery of primary leukemic cells, to be used for in vitro and in vivo studies. Furthermore, several leukemic animal models, including genetic leukemia models, transplantation models, and xenograft models, are being utilized in the studies.
