Generation of immunodeficient rats with Rag1 and Il2rg gene deletions and human tissue grafting models (original) (raw)

Transplantation, 2018

Abstract

Immunodeficient mice are invaluable tools to analyze the long-term effects of potentially immunogenic molecules in the absence of adaptive immune responses. Nevertheless, there are models and experimental situations that would beneficiate of larger immunodeficient recipients. Rats are ideally suited to perform experiments in which larger size is needed and are still a small animal model suitable for rodent facilities. Additionally, rats reproduce certain human diseases better than mice, such as ankylosing spondylitis and Duchenne disease and these disease models would greatly benefit of immunodeficient rats to test different immunogenic treatments. We describe the generation of Il2rg-deficient rats and their crossing with previously described Rag1-deficient rats to generate double-mutant RRG animals. As compared to Rag1-deficient rats, Il2rg-deficient rats were more immunodeficient since partially lacked not only T and B cells but also NK cells. RRG animals showed a more profound im...
