21. Collagenous Colitis : A Study of Inflammatory Mediators and Growth Factors Based on Segmental Colorectal Perfusion and Immunohistochemistry
Sammanfattning : Collagenous colitis (CC) is an inflammatory bowel disease of unknown etiology. It is characterized by watery diarrhoea without blood, normal endoscopic findings but microscopically colonic mucosal inflammation and increased thickness of the subepithelial collagen band, the latter being a pathognomonic sign.

22. Molecular mechanisms of VEGF-mediated angiogenesis and vascular permeability
Sammanfattning : Angiogenesis, sprouting of new capillaries from pre-existing blood vessels, is a tightly regulated multi-step process. One of the key mediators in this process is the Vascular Endothelial Growth Factor (VEGF). Many tumors express high levels of VEGF and pathological angiogenesis is considered a hallmark of malignant tumor growth. LÄS MER
23. Role of extracellular retention of platelet-derived growth factor-B. Functions in development and disease
Sammanfattning : During development, the cell secretes growth and differentiation factors (GDFs) to the surrounding microenvironment. These factors are often key regulators of organogenesis and embryogenesis. Several GDFs carry sequences that mediate specific interaction with molecules of the extracellular matrix (ECM) that surrounds the cell. LÄS MER
24. Effects of Ischaemia on the Neuroretina and Retinal Blood Vessels
Sammanfattning : Identification of the intracellular signal transduction pathways activated in retinal ischaemia may be important in revealing novel pharmacological targets. The retinal blood vessels are key organs in circulatory failure, and in this work the retinal vasculature was therefore examined separately from the neuroretina. LÄS MER
25. New Roles of Filamins in Cell Signaling, Transcription and Organ Development
Sammanfattning : Filamins are large actin-binding proteins that stabilize delicate three-dimensional actin networks and link them to cellular membranes. They integrate cell architectural and signaling functions and are essential for cell locomotion and development. LÄS MER
