Master´s Project

Hemostasis and thrombosis
Medical University of Vienna


Thrombospondin-1 (TSP-1) is a protein which is secreted by activated platelets and endothelial cells and promotes blood clotting by various mechanisms: TSP-1 supports platelet adhesion, it functions as a bridging molecule in platelet aggregation, and it protects platelet strings from degradation. Inflammatory cells such as neutrophilic granulocytes can process thrombospondin-1 to a smaller protein variant which has more potent hemostatic properties.

This Master´s project is designed to characterize the cellular interactions and molecule turnover of these TSP-1 isoforms in more detail: Fusion variants of TSP-1 and fluorescent proteins will be constructed, recombinantly produced and purified. Platelets deficient in TSP-1 will be isolated from TSP-1 k.o. mice and exposed to co-culture with neutrophils. The cell binding, internalization and degradation of fluorescent TSP-1 fusion proteins will be monitored by confocal laser scanning microscopy.

This project is conducted in the context of an FWF-funded research consortium (FWF SFB-54; https://inthro.meduniwien.ac.at/) which addresses the link between inflammation and thrombosis. It is designed to determine whether proteolytic processing of TSP-1 is a mechanism by which inflammatory reactions can alter the function of TSP-1 thereby promoting blood clotting and the tendency for thrombotic events.
