11. Lipid Signalling Dynamics in Insulin-secreting β-cells
Sammanfattning : Certain membrane lipids are involved in intracellular signalling processes, among them phosphoinositides and diacylglycerol (DAG). They mediate a variety of functions, including the effects of nutrients and neurohormonal stimuli on insulin secretion from pancreatic β-cells. LÄS MER
12. β-adrenergic regulation of glucose transporters
Sammanfattning : The transport of glucose across the plasma membrane is a fundamental mechanism to provide cells with its basic requirements for energy yielding processes. It is also vital for clearing glucose from blood into tissues, a process normally stimulated by the hormone insulin in mammals. LÄS MER
13. Calcium and Phospholipases in Orexin Receptor Signaling
Sammanfattning : The neuropeptides orexin-A and -B act as endogenous ligands for G-protein-coupled receptors (GPCRs) called OX1 and OX2 receptors. Previous observations have established that orexin receptors have an ability to couple to different G-proteins and signaling pathways and induce Ca2+ elevations via both receptor-operated Ca2+ channels (ROCs) and store-operated Ca2+ channels (SOCs).

14. Structural and Functional Aspects of β1 Integrin Signalling
Sammanfattning : Integrins are transmembrane glycoproteins primarily mediating interactions of cells with the extracellular matrix. Each receptor is a complex of one α- and one β-subunit with affinity for a diverse set of ligands. LÄS MER
15. Regulation of neutrophil apoptosis
Sammanfattning : The human neutrophil is the most abundant granulocyte and the major type of cell involved in an acute inflammatory response. Neutrophils are armed with various systems of enzymes, that can find and kill pathogens, but unfortunately, these "weapons" cannot distinguish between the host tissues and the "invaders. LÄS MER
