• the hypergammaglobulinemia, autoantibody production, reduced frequencies of marginal zone B cells and monocytosis, renal disease, and premature morbidity that are found in Yaa bearing mice with at least one wildtype copy of the interleukin 21 receptor are ameliorated or prevented by the disruption of the interleukin 21 receptor (J:144484)
• unlike IL21R heterozygous B2M null controls, these double homozygotes do not develop the Lupus-like autoimmune syndrome caused by Yaa and generally survive beyond 40 weeks of age (J:179430)
