11. Aspects of proteinase-activated receptor-2: A sensor of enzymatic activity at the cell surface
Sammanfattning : Information about extracellular proteolytic activity is transduced to the cell by a transmembrane G-protein coupled receptor subfamily. These receptors are activated by proteolytic cleavage in the extracellular amino-terminal domain and are thus termed proteinase-activated receptors (PARs). LÄS MER
12. Growth factor receptor signalling in thyrocytes of normal and neoplastic origin
Sammanfattning : Cellular growth and function are controlled by stimulatory and inhibitory factors actingthrough specific receptors. The present thesis focuses on the role of growth factors, theirreceptors and signalling pathways in normal and neoplastic thyroid epithelial cell biology. LÄS MER
13. Injury-induced activation of vascular smooth muscle cells. Role of specific gene expression and intracellular signalling pathways
Sammanfattning : Migration and proliferation of smooth muscle cells (SMC) are important events in the development of atherosclerosis and restenosis following angioplastic surgery. It is important to gain further knowledge about the mechanisms regulating SMC form and function in order to understand the underlying disease process. LÄS MER
14. Alzheimer's disease mutations and cellular signalling
Sammanfattning : Alzheimer's disease is the most frequent cause of dementia in elderly and is characterised neuropathologically by the extracellular deposition of amyloid plaques (containing the 39-43 amino acid Abeta peptide), as well as intracellular neurofibrillary tangles (NFTs) composed primarily of an abnormally hyperphosphorylated form of the microtubule-associated protein tau. A proportion (10- 15%) of Alzheimer's disease cases is familial, the remainder being sporadic. LÄS MER
15. Nephrin : intracellular trafficking and podocyte maturation
Sammanfattning : Congenital nephrotic syndrome of the Finnish type, CNF, is an autossomal recessive disorder caused by mutations in the NPHS1 gene and, consequently, in its product nephrin, a 180 kDa transmembrane protein belonging to the immunoglobulin superfamily of adhesion molecules. In kidneys, nephrin is located exclusively to the podocyte slit diaphragm and it has a key role in organising amd maintaining the renal ultrafiltation barrier. LÄS MER
