21. Cellular responses to amyloid-beta protofibrils : Focus on astrocytes, extracellular vesicles and antibody treatment
Abstract : Knowledge about the cellular mechanisms behind the initiation and propagation of Alzheimer’s disease (AD) is limited. Decades of research have focused on neuronal abnormalities in AD, but recently more attention has been given to the glial cells. READ MORE

22. Effects of Antioxidants and Pro-oxidants on Oxidative Stress and DNA Damage using the Comet Assay : Studies on Blood Cells from Type 2 Diabetes Subjects and Mouse Lymphoma Cells
Abstract : Diet and oral supplements comprise two distinct sources of antioxidants known to prevent oxidative stress. Beneficial effects from antioxidants have been seen for patients at risk for type 2 diabetes.The aim of this thesis was to evaluate the positive effects of antioxidants against oxidative stress and DNA damage in type 2 diabetes subjects.

23. Maf transcription factors in beta cell function
Abstract : Diabetes mellitus is metabolic disorder caused by a defect or lack of beta cell-produced insulin that controls blood glucose homeostasis. In addition to glucose, insulin secretion is regulated by the autonomic nervous system (ANS); the neurotransmitter acetylcholine as well as monoamines, such as dopamine, serotonin, melatonin and norepinephrine.

24. Exocytosis in insulin secreting cells - role of SNARE-proteins
Abstract : Type 2 diabetes is marked by deterioration in pancreatic β-cell function. SNARE-proteins are crucial for the fusion of insulin granules with the plasma membrane, a prerequisite for insulin secretion. READ MORE

25. Palmitate-induced Apoptosis in Insulin-producing β-cells
Abstract : Type 2 diabetes is a disease characterized by the inability of pancreatic β-cells to secrete sufficient amounts of insulin to maintain normoglycemia. Increased levels of saturated fatty acids such as palmitate are believed to contribute to β-cell failure and the development of the disease. READ MORE
