11. Ion channels in drug discovery : focus on biological assays
Sammanfattning : Ion channels are well characterised drug targets. However, the techniques used to study ion channel pharmacology have not been particularly applicable to modern drug discovery. LÄS MER
12. K+ channels and the regulation of synaptic transmission
Sammanfattning : Neuronal excitability is highly regulated by K+ channels that are activated by a voltage change across the plasma membrane or by a rise in intracellular Na+ or Ca2+ concentration. The main focus of this thesis has been to characterize the Na+-activated K+ (KNa) and the Ca2+-activated K+ (KCa) channels and to determine their role in regulating synaptic transmission in the lamprey spinal cord.

13. Effects of imidazoline compounds on intracellular CA2+ and apoptosis
Sammanfattning : Cytoplasmic free Ca2+ concentration ([Ca2+]i) plays a pivotal role in the regulation of insulin release from the pancreatic beta-cell. [Ca2+]i is also important in the control of apoptosis. LÄS MER
14. Regulation of glucagon secretion from pancreatic alpha cells
Sammanfattning : Glucagon secreted by pancreatic α-cells plays an important role in the regulation of blood glucose. In this thesis, different techniques such as electrophysiology, immunohistochemistry and hormone secretion assay were combined to explore the mechanisms by which glucagon secretion is regulated.

15. Investigation on Pre- and Postsynaptic Ca2+ Signaling in Neuronal Model Systems
Sammanfattning : Communication between neuronal and non-neuronal is called volume transmission when the released neurotransmitter (NT) acts via diffusion and affects several target cells. Both the neurosecretory and postsynaptic cell responses are linked to [Ca2+]i elevations. LÄS MER
