1. Nature of Large Vesicle Exocytosis in Pancreatic β-cells: Release of ATP and GABA
Sammanfattning : Several high resolution electrophysiological techniques such as measurements of cell membrane capacitance and amperometry are used to detect exocytotic events. A novel method was developed in this study based on the expression of P2X2 receptor channel in secreting cells. LÄS MER
2. Mechanisms of insulin exocytosis and release
Sammanfattning : Endocrine cells as well as neurons release their hormones and transmitters by regulated exocytosis. In the pancreatic B-cell, stimuli like glucose initiate biochemical and electrical processes that culminate in influx of Ca2+, which then triggers exocytosis of insulin-containing granules. LÄS MER
3. New Electrochemical Tools to Study Exocytosis
Sammanfattning : The work described in this thesis has the focus on the development of new analytical tools to study processes related to cellular secretion (exocytosis) in cell models. Four novel techniques were developed, allowing new ways to study processes related to exocytosis, and gain previously unattainable knowledge. LÄS MER
4. Exocytosis in insulin secreting cells - role of SNARE-proteins
Sammanfattning : 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. LÄS MER
5. Molecular and physiological regulation of adiponectin exocytosis in white adipocytes
Sammanfattning : .... LÄS MER
