Introduction: Type 1 diabetes mellitus is a chronic metabolic disease caused by autoimmune destruction of pancreatic beta cells. The theory of the disease onset is derived from study of a disease course in non-obese diabetic (NOD) mice, in which the diabetes occurs due to a dysregulation of the immune system. Experimental and clinical studies showed that the autoimmunity may be abrogated by immune intervention, which if initiated early enough may at least slow down the ongoing beta cells lost and preserve residual insulin secretion. But immune intervention alone is not sufficient to restore normoglycemia in the majority of cases. Several interventional studies showed that stimulation of proliferation and/or regeneration of beta cells are necessary to restore normoglycemia in animal models. Aim of the study: To find out, if the combination of a potent immunosuppression (murine anti-thymocyte globulin (mATG), gusperimus) together with stimulation of islet regeneration (sitagliptin) will be able to slow down or reverse the course of the disease. Another aim is to identify the mechanism by which the substances act. Material and methods: All experiments were performed in female NODShiLtJ (H2g7 ) mice. The following parameters were examined at day 0, 7, 14 and 28: blood glucose, subpopulations of...
