Abstract:

Genetically modified non-human animals expressing human SIRP.alpha. and human IL-15 from the non-human animal genome are provided. Also provided are methods for making non-human animals expressing human SIRP.alpha. and human IL-15 from the non-human animal genome, and methods for using non-human animals expressing human SIRP.alpha. and human IL-15 from the non-human animal genome. These animals and methods find many uses in the art, including, for example, in modeling human T cell and/or natural killer (NK) cell development and function, in modeling human pathogen infection of human T cells and/or NK cells, and in various in vivo screens.
