Abstract: An object of the present invention is to provide an immunodeficient mouse which is capable of eliminating effects of immune cells from the immunodeficient mouse against human antibodies and in which human cells are engrafted at high level. Deletion of a mouse FcgR gene from an NOG mouse results in a mouse that does not exhibit antibody-dependent cellular cytotoxic activity on tumors, and in the mouse, human cells can be engrafted at significantly higher level than that in the NOG mouse. Furthermore, by introducing the human IL-15 gene into the mouse and engrafting a human NK cell in the mouse, only human NK cells become effector cells to enable evaluation of ADCC activity.
