1. Beta Cell Function: from Human Genetics to Animal Models
Sammanfattning : Beta cell function is an important factor in the development of both Type 1 (T1D) and Type 2 (T2D) diabetes mellitus. T1D is characterized by a primary defect in insulin secretion due to the immune-mediated beta cell destruction, however, the more common T2D beside insulin resistance also include impaired beta cell function as a consequence to abnormal glucose homeostasis.

2. 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
3. Glucose, Palmitate and Apolipoprotein CIII-induced Effects on Insulin-Producing β-cells
Sammanfattning : Background and aims: Type 2 diabetes mellitus results from complex interplay between genetic predisposition and environmental factors that together promote impairment of insulin-producing β-cells. Elevated levels of glucose, fatty acid palmitate and apolipoprotein CIII (apoCIII) are implicated in this process. LÄS MER
4. Roles of the transient receptor potential channels and the intracellular Ca2+ channels in Ca2+ signaling in the beta-cells
Sammanfattning : Previous studies from our group reported that pancreatic β-cells express ryanodine receptors (RyRs) that can mediate Ca2+-induced Ca2+ release (CICR). The full consequences of the activation of RyRs on Ca2+ signaling in these cells, however, remained unclear. LÄS MER
5. The impact of glucotoxicity on pancreatic β-cell function
Sammanfattning : Type 2 diabetes mellitus is connected with elevated plasma glucose levels which negatively influence β-cells and cause impaired glucose-stimulated insulin secretion (GSIS). The aim of present thesis was to investigate the impact of long-term hyperglycemia on the pancreatic islet β-cell function. LÄS MER
