Title:
IMMUNODEFICIENT MOUSE
Document Type and Number:
WIPO Patent Application WO/2020/067199
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an immunodeficient mouse that is capable of excluding the influence of immunodeficient mouse-derived immune cells on human antibodies and has high engraftment of human cells. When a mouse FcgR gene is additionally deleted from a NOG mouse, the mouse does not express antibody-dependent cytotoxicity activity to tumors, and human cells are engrafted at a significantly higher rate compared to a NOG mouse. Furthermore, by engrafting human NK cells to the mouse that is introduced with a human IL-15 gene, only the human NK cells become effector cells, and ADCC activity can be evaluated.
