abstractText | The nonobese diabetic (NOD) mouse strain has a genetic deficiency in natural killer (NK) cells. This defect underlies this strain's utility in several experimental settings; in particular, it promotes engraftment of human tissue in NOD hosts during the generation of 'humanized' mouse models. We have mapped the major NK-cell defect in the NOD vs. C57BL/6 (B6) strain to an inadequately expressed Il15 allele. Treatment of NOD mice with a reagent that specifically enhances interleukin (IL)-15 bioavailability normalized NK-cell numbers and activity in the absence of nonspecific stimulation. These findings raise the possibility of exploiting reagents that impact the IL-15 receptor pathway to facilitate construction of humanized mouse models on non-NOD genetic backgrounds. |
