Abstract

The “R2G2” (B6;129-Rag2tm1FwaIL2rgtm1Rsky/DwlHsd) knockout mouse is the latest advancement to provide an alternative option in the highly immunodeficient mouse model category for oncology, immunology and other biomedical research communities. This model was generated by backcrossing an IL2rg (common gamma) knockout model to a RAG2 (recombinase activating gene) knockout model. The resulting mouse lacks various cytokines including IL-2, IL-4, IL-7, IL-9 and IL-15. In addition, this model lacks B cells, T cells, NK cells and has a deficiency in lymphocyte development. The R2G2 mouse model is not only ultra immunodeficient, but provides a model that is less leaky and more tolerant to gamma radiation than traditional SCID models. Herein we describe the development and characterization of the R2G2 mouse model, which includes breeding history, growth curve, complete blood count and serum chemistry, flow cytometry, tumor growth and radiosensitivity.
