endocrine/exocrine glands
insulitis ( J:91865 )

immune system
insulitis ( J:91865 )
• by 40 weeks, pancreata of transgenic mice show extensive infiltrates
abnormal B cell number ( J:91865 )
• V125 transgene-carrying mice have more B220+ cells that bind insulin compared to NOD controls or V281 transgene-carrying mice
increased susceptibility to autoimmune diabetes ( J:91865 )
• transgenic females develop diabetes (2 consecutive blood glucose measurements >200 mg/dl) at an accelerated rate; 95% develop diabetes by 40 weeks

hematopoietic system
abnormal B cell number ( J:91865 )
• V125 transgene-carrying mice have more B220+ cells that bind insulin compared to NOD controls or V281 transgene-carrying mice

homeostasis/metabolism
increased circulating glucose level ( J:91865 )
• mice are diabetic if 2 consecutive blood glucose measurements are >200 mg/dl

insulitis ( J:91865 )
• the percentage of islets infiltrated is slightly increased in Igh-6-heterozygous transgenic mice
increased susceptibility to autoimmune diabetes ( J:91865 )
• transgenic females heterozygous for Igh-6 develop diabetes (2 consecutive blood glucose measurements >200 mg/dl) at a slightly earlier time (12 weeks) than homozygous transgenic females but the incidence is the same by 17 weeks
