Detailed Description

The Ifngr2 allele was made in W9.5 ES cells (129S1/Sv-p⁺ Tyr⁺ Kitl^Sl-J/+ background) and was imported into The Jackson Laboratory from Paul Rothman on a B6,129 segregating background. It was backcrossed onto NOD/Lt and a genome scan was run to select for NOD/Lt markers at Idd1 through Idd15 (performed as described in Serreze et al., J Exp Med, 1996). This strain was then fixed homozygous at N8. It is maintained by sibling breeding homozygotes. (Serreze et al., 2000, Lu et al., 1998.)

abnormal diapedesis
- CD8+ T cells injected into Ifngr2-deficient NOD mice are less able to cause diabetes, due to impaired homing ability and impaired diapedesis

abnormal T-helper 2 physiology
- enhanced Th2 responses

immune system phenotype

- enhanced Th2 responses

abnormal cytotoxic T cell physiology
- CD8+ T cells injected into Ifngr2-deficient NOD mice are less able to cause diabetes, due to impaired homing ability and impaired diapedesis

decreased susceptibility to autoimmune diabetes
- when diabetogenic splenocytes are injected into Ifngr2-deficient NOD mice, diabetes development is delayed compared to wild-type NOD mice

abnormal diapedesis
- CD8+ T cells injected into Ifngr2-deficient NOD mice are less able to cause diabetes, due to impaired homing ability and impaired diapedesis

mammalian phenotype

homeostasis/metabolism phenotype
- Normal - unexpectedly, incidence of type 1 diabetes in females was unchanged
