cellular
abnormal diapedesis ( J:72818 )
• CD8+ T cells injected into Ifngr2-deficient NOD mice are less able to cause diabetes, due to impaired homing ability and impaired diapedesis

immune system
abnormal diapedesis ( J:72818 )
• 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 ( J:65986 )
• enhanced Th2 responses
abnormal cytotoxic T cell physiology ( J:72818 )
• 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 ( J:72818 )
• when diabetogenic splenocytes are injected into Ifngr2-deficient NOD mice, diabetes development is delayed compared to wild-type NOD mice

homeostasis/metabolism
homeostasis/metabolism phenotype ( J:65986 )

• unexpectedly, incidence of type 1 diabetes in females was unchanged

hematopoietic system
abnormal diapedesis ( J:72818 )
