Research focuses:

  • Cell and molecular biology of the islets of Langerhans
  • Mechanisms of glucose-induced insulin secretion and signal recognition in pancreatic beta cells
  • Molecular biology of glucose transport (GLUT2 glucose transporter) and glucose phosphorylation (glucokinase) in beta cells and liver
  • Mechanisms of selective beta cell dysfunction and death by necrosis and apoptosis through cytokines (T1DM) and lipotoxicity (T2DM)
  • Importance of cytoprotective enzymes for protection against beta cell death
  • Mechanisms of diabetogenic action of alloxan and streptozotocin
  • Bioengineering of insulin-producing surrogate cells through differentiation of stem cells
  • Mechanisms of action of antihyperglycemic drugs
  • Gene therapy of insulin-dependent diabetes mellitus (IDDM)
  • Type 1 and type 2 diabetes animal models
  • The LEW.1AR1.-iddm rat (IDDM rat) as an animal model of human T1DM and the characterisation of the underlying pathomechanisms of beta cell death in autoimmune diabetes
  • Immunomodulatory therapies for prevention and cure of T1DM
