|
| ♀ | phenotype observed in females |
| ♂ | phenotype observed in males |
| N | normal phenotype |
|
• mice are diabetic; diabetes assessed by blood glucose measures >250 mg/dl on two consectutive measurements
|
|
• diabetic mice have nearly complete destruction of insulin producing cells
|
|
• thymus weight is variable, with some being normal and others having very low weight
• transgene expression in Rag1-deficient mice increases thymus cellularity and thymus weight almost to levels seen in NOD controls
|
|
• thymus weight is variable, with some being normal and others having very low weight
• transgene expression in Rag1-deficient mice increases thymus cellularity and thymus weight almost to levels seen in NOD controls
|
|
• mice have greater percentage of double-positive T cells (93%) in the thymus compared to other genotypes
|
|
• mice are lymphopenic compared to Rag1-sufficient transgenic mice and control NOD animals; number of lymphocytes in peripheral blood is lower than in transgenic Rag1-sufficient mice both in percentage of total white blood cell count and absolute lymphocyte count
|
|
• mice have lower percentage of single positive CD4+ T cells (3%) in the thymus compared to other genotypes
|
|
• mice develop spontaneous diabetes aged 4-32 weeks; diabetes develops only in mice with at least 1 copy of H-2g7 (incidence is 50% with homozygosity, 15% in heterozygotes); both sexes of transgenic mice are equally affected
|
|
• thymus weight is variable, with some being normal and others having very low weight
• transgene expression in Rag1-deficient mice increases thymus cellularity and thymus weight almost to levels seen in NOD controls
|
|
• mice have greater percentage of double-positive T cells (93%) in the thymus compared to other genotypes
|
|
• mice are lymphopenic compared to Rag1-sufficient transgenic mice and control NOD animals; number of lymphocytes in peripheral blood is lower than in transgenic Rag1-sufficient mice both in percentage of total white blood cell count and absolute lymphocyte count
|
|
• mice have lower percentage of single positive CD4+ T cells (3%) in the thymus compared to other genotypes
