immune system
salivary gland inflammation ( J:68641 )
• transgenic mice develop sialadenitis and severity is associated with diabetes development
abnormal CD4-positive, alpha beta T cell morphology ( J:68641 )
• coexpression of DR4 and DQ8 transgenes increases CD4+ T cell numbers 2-fold compared to either DR4 or DQ8 single transgenic line
abnormal CD8-positive, alpha beta T cell morphology ( J:68641 )
• there are fewer CD8+ T cells in pancreatic infiltrates than in MHC class II-deficient mice expressing only DQ8
decreased susceptibility to autoimmune diabetes ( J:68641 )
• incidence of diabetes (blood glucose >250 mg/dl; 5/22, 23%) is lowered from incidence in MHC class II-deficient mice expressing the DQ8 transgene (73%) and similar to deficient mice transgenic for DR4

endocrine/exocrine glands
salivary gland inflammation ( J:68641 )
• transgenic mice develop sialadenitis and severity is associated with diabetes development

hematopoietic system
abnormal CD4-positive, alpha beta T cell morphology ( J:68641 )
• coexpression of DR4 and DQ8 transgenes increases CD4+ T cell numbers 2-fold compared to either DR4 or DQ8 single transgenic line
abnormal CD8-positive, alpha beta T cell morphology ( J:68641 )
• there are fewer CD8+ T cells in pancreatic infiltrates than in MHC class II-deficient mice expressing only DQ8

digestive/alimentary system
salivary gland inflammation ( J:68641 )
