New Electrochemical Tools to Study Exocytosis
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. The methods were applied to single cells as well as to populations of cells in culture...
متن کاملExocytosis, Endocytosis, and Their Coupling in Excitable Cells
Evoked exocytosis in excitable cells is fast and spatially confined and must be followed by coupled endocytosis to enable sustained exocytosis while maintaining the balance of the vesicle pool and the plasma membrane. Various types of exocytosis and endocytosis exist in these excitable cells, as those has been found from different types of experiments conducted in different cell types. Correlat...
متن کامل4-Аminopyridine sequesters intracellular Ca2+ which triggers exocytosis in excitable and non-excitable cells
4-aminopyridine is commonly used to stimulate neurotransmitter release resulting from sustained plasma membrane depolarization and Ca2+-influx from the extracellular space. This paper elucidated unconventional mechanism of 4-aminopyridine-stimulated glutamate release from neurons and non-neuronal cells which proceeds in the absence of external Ca2+. In brain nerve terminals, primary neurons and...
متن کاملThe Mechanisms of Exocytosis Studied in Cells and Models with Amperometry
Cover picture: Schematic of amperometric detection of exocytosis at a neuroendocrine cell. iii To Mike and Julia iv v ABSTRACT Exocytosis is the universal basis for neuronal communication, allowing the controlled release of neurotransmitter molecules from the presynaptic cell. Exocytosis has been widely studied in many systems. However, the details of this vital process are not fully understood...
