Abstract english

Studies on the pathogenic process in type 1 diabetes are often performed in animal models. Low-dose administration of streptozotocin has been used to induce diabetes with pathological alterations similar to human type 1 diabetes in the animals. Rodent models are frequently used but there is a need of developing new models including larger animals. In this study we wanted to investigate to what extent a minipig was sensitive to low-dose streptozotocin for induction of diabetes with features of human Type I diabetes. A female Göttingen minipig received two low-doses (40 mg/kg) of streptozotocin with an 11-day interval. Serum was analysed for the presence of the enzyme glutamic acid decarboxylase, isoform 65, (GAD65) and autoantibodies against glutamic acid decarboxylase, isoform 65 (GAD65A), isoform 67 (GAD67A), insulinoma antigen 2 (IA-2) and insulin (IAA). Pancreas tissue was fixated in formaldehyde and was sent for pathoanatomical examination. The minipig became hyperglycaemic after t
