1. Glucotoxicity in Insulin-Producing β-Cells
Sammanfattning : Background and aims: Type 2 diabetes mellitus is connected with elevated glucose levels, which cause impaired glucose-stimulated insulin secretion (GSIS) and degeneration of β-cells. Mechanisms for such glucotoxic effects were explored in the present study.Materials and methods: INS-1E cells were cultured for 5 days in 5. LÄS MER
2. Protein tyrosine kinases in insulin producing cells : Expression and putative importance for beta-cell function
Sammanfattning : Protein tyrosine kinases are of importance for cell replication and differentiation in manysystems. The mechanisms controlling the replication and differentiation of insulin producingcells are unknown. LÄS MER
3. Regulation of cytokine-induced nitric oxide production in insulin-producing cells
Sammanfattning : Cytokine-induced expression of the inducible form of nitric oxide synthase (iNOS) and production of nitric oxide (NO) may contribute to pancreatic β-cell damage during the development of type 1 diabetes. iNOS catalyses the conversion of arginine into citrulline and NO, a reaction regulated by the amount of expressed iNOS enzyme and by the cellular availability of arginine.

4. Insulin-Producing Cells, Iron, Oxidative Stress, and Lysosomal Pathology
Sammanfattning : Accumulating evidence suggests that injnries caused by oxygen-derived radicals contribute to the destruction of pancreatic islet ß-cells in autoinnnune diabetes mellitus (diabetes type I, or IDDM). Oxidative stress may be caused by an enhanced production of oxygen-derived radicals, or by a decreased scavenging of such molecules. LÄS MER
5. Embryonic Stem Cells: Differentiation into Insulin Producing Cells and Elimination of Damaged Proteins
Sammanfattning : This thesis includes two different parts: One focusing on how to induce human embryonic stem cells (hESCs) to differentiate into insulin producing cells by following the normal pancreatic development pathway. These cells have then the potential to be an unlimited source for diabetes regenerative medicine. LÄS MER
