Interleukin-2 Receptor Gamma Deficient Mice, Widely Used Research Tools
In 1995, Dr. Warren J. Leonard of the National Heart, Lung, and Blood Institute (NHLBI), National Institutes of Health (NIH), reported the creation of an interleukin-2 receptor gamma chain (IL-2Rg) deficient mouse. His lab also demonstrated earlier that mutations in the gene encoding IL-2Rg result in X-linked severe combined immunodeficiency (XSCID) and that IL-2Rg is a subunit common to multiple cytokine receptors. The IL-2Rgdeficient mice created by Dr. Leonard provide a unique animal model, the first of its kind, to study XSCID and other immune deficiencies.
