NSG mice grafted with thymus/oncogenic HSC develop human immune system and leukemia.
Leukemia transfer to mice with autologous immunity suffices to model immunotherapy.
Lymphopenia enhances RLI-mediated HVGR and anti-leukemia activity in mixed chimeras.
This study establishes a humanized mouse model with human immunity and autologous leukemia. Using this model, the authors demonstrate that lymphopenia promotes the rejection of donor hematopoietic chimerism and the associated anti-leukemia response by recipient leukocyte infusion in mixed allogeneic chimeras.
